## Testing the Stack
### 1. Backend Health Check
```bash
curl http://localhost:8000/api/health
```
Expected response:
```json
{
"status": "healthy",
"version": "0.1.0"
}
```
### 2. PM3 Status
```bash
curl http://localhost:8000/api/pm3/status
```
Expected response (with mock):
```json
{
"connected": true,
"device": "/dev/ttyACM0",
"version": null,
"session_active": false
}
```
### 3. Execute Command
```bash
# Create session
curl -X POST http://localhost:8000/api/system/session/create \
-H "Content-Type: application/json" \
-d '{"force_takeover": false}'
# Execute command (replace SESSION_ID)
curl -X POST http://localhost:8000/api/pm3/command \
-H "Content-Type: application/json" \
-d '{
"command": "hw version",
"session_id": "SESSION_ID"
}'
```
### 4. SSE Events
```bash
# Connect to SSE stream
curl -N http://localhost:8000/sse/events
```
You should see:
```
event: connected
data: {"message":"Connected to Dangerous Pi event stream"}
```
---
## Using the Web Interface
### Dashboard
- View system status (CPU, memory, disk)
- Check PM3 connection
- Quick action buttons
- Real-time event notifications
### Commands Page
1. Click "Commands" in navigation
2. Enter a PM3 command (e.g., `hw status`)
3. Click "Execute" or press Enter
4. View output in terminal-style display
5. Use ↑/↓ arrow keys to navigate history
**Quick Commands:**
- `hw status` - Hardware status
- `hw version` - Firmware version
- `hf search` - Search for HF tags
- `lf search` - Search for LF tags
- `hw tune` - Tune antenna
### Settings Page
- View current configuration
- Change Wi-Fi mode (planned)
- Enable/disable features
- Restart backend or shutdown system
### Logs Page
- View command history
- See success/failure status
- Export logs (planned)
---
## Development Tips
### Hot Reload
Both backend and frontend support hot reload:
- **Backend**: Uvicorn watches for file changes
- **Frontend**: Vite HMR (Hot Module Replacement)
Edit code and see changes immediately!
### Mock PM3 vs Real PM3
The backend automatically uses `MockPM3Worker` when the `pm3` module is not available.
**Mock responses:**
```python
"hw version" → "Proxmark3 RFID instrument\n client: RRG/Iceman/master/v4.14831"
"hw status" → "Device: PM3 GENERIC\nBootrom: master/v4.14831"
"hw tune" → "Measuring antenna characteristics..."
```
**To use real PM3:**
1. Install Proxmark3 client with Python support
2. Connect PM3 hardware
3. Set `PM3_DEVICE` environment variable
4. Restart backend
### Theme Toggle
Click the theme button (◐ / ○ / ◑) in the header to cycle:
- **Dark** → **Auto** → **Light** → **Dark**
Default is Dark (cyberpunk aesthetic for Dangerous Things).

## Troubleshooting
### Backend won't start
**Error: Port 8000 already in use**
The existing pi-pm3 uses ttyd on port 8000. Either:
- Change PORT to 8001 in config
- Stop ttyd: `sudo systemctl stop ttyd-bash`
**Error: pm3 module not found**
Expected during development. The mock worker will be used automatically.
### Frontend won't start
**Error: Cannot connect to backend**
Make sure backend is running on http://localhost:8000
**Error: npm install fails**
Try:
```bash
rm -rf node_modules package-lock.json
npm install
```
### SSE not working
Check browser console for errors. SSE requires:
- Backend running
- Modern browser (no IE11)
- No aggressive ad blockers
---
## Next Steps
1. **Try the interface**: Execute some commands
2. **Explore the code**: See how SSE, workers, and sessions work
3. **Add features**: Wi-Fi manager, updates, backups
4. **Test on Pi**: Transfer code to actual hardware
5. **Customize theme**: Edit `app/frontend/app/styles.css`

# Port Conflict Resolution
## Overview
The existing pi-pm3 setup includes ttyd services that provide web-based terminal access:
- **ttyd-bash** on port `8000` - Bash terminal
- **ttyd-pm3** on port `8080` - Proxmark3 terminal
- **RaspAP** on port `80` - WiFi management interface
Dangerous Pi's FastAPI backend defaults to port `8000`, which **conflicts with ttyd-bash**.
## Resolution Options
You have several options to resolve this conflict:
### Option 1: Disable ttyd-bash (Recommended)
**Use this if**: You plan to use Dangerous Pi's web interface instead of the ttyd terminals.
**Steps**:
```bash
sudo systemctl stop ttyd-bash
sudo systemctl disable ttyd-bash
```
**Pros**:
- Simple and clean
- Frees up port 8000 for Dangerous Pi
- Reduces resource usage
**Cons**:
- Loses standalone bash terminal (can use Dangerous Pi's terminal instead)
### Option 2: Change Dangerous Pi Port to 8001
**Use this if**: You want to keep both ttyd-bash and Dangerous Pi running simultaneously.
**Steps**:
```bash
# Edit environment file
sudo nano /opt/dangerous-pi/.env
# Change PORT line to:
PORT=8001
# Restart service
sudo systemctl restart dangerous-pi
```
**Access Dangerous Pi at**: `http://<pi-ip>:8001`
**Pros**:
- Both services available
- No modification to existing ttyd setup
**Cons**:
- Non-standard port for Dangerous Pi
- Slightly more complex URL
### Option 3: Change ttyd-bash Port to 8002
**Use this if**: You want Dangerous Pi on the standard port 8000 but still want ttyd-bash available.
**Steps**:
```bash
# Edit ttyd-bash service
sudo nano /etc/systemd/system/ttyd-bash.service
# Find the line with --port 8000 and change to:
# --port 8002
# Reload and restart
sudo systemctl daemon-reload
sudo systemctl restart ttyd-bash
```
**Access ttyd-bash at**: `http://<pi-ip>:8002`
**Pros**:
- Dangerous Pi on standard port
- ttyd-bash still available
**Cons**:
- Requires modifying existing service
- ttyd-bash on non-standard port
## Automated Resolution Script
For convenience, use the included resolution script:
```bash
/opt/dangerous-pi/scripts/resolve-port-conflict.sh
```
This interactive script will guide you through the options above.
## Port Summary
After resolution, your ports may look like:
### Configuration A (Option 1 - Disable ttyd-bash)
- Port `80` - RaspAP
- Port `8000` - **Dangerous Pi** ✓
- Port `8080` - ttyd-pm3
- ttyd-bash - Disabled
### Configuration B (Option 2 - Dangerous Pi on 8001)
- Port `80` - RaspAP
- Port `8000` - ttyd-bash
- Port `8001` - **Dangerous Pi** ✓
- Port `8080` - ttyd-pm3
### Configuration C (Option 3 - ttyd-bash on 8002)
- Port `80` - RaspAP
- Port `8000` - **Dangerous Pi** ✓
- Port `8002` - ttyd-bash
- Port `8080` - ttyd-pm3
## Pi-gen Build Integration
If you're building a custom image with pi-gen, you can pre-configure the resolution:
Edit `/home/work/dangerous-pi/pi-gen/stageDTPM3/04-dangerous-pi/01-run-chroot.sh` and uncomment the desired option:
```bash
# Option 1: Disable ttyd-bash
if systemctl is-enabled ttyd-bash 2>/dev/null; then
systemctl disable ttyd-bash
fi
# OR Option 2: Change Dangerous Pi port
sed -i 's/^PORT=.*/PORT=8001/' /opt/dangerous-pi/.env
# OR Option 3: Change ttyd-bash port
sed -i 's/--port 8000/--port 8002/' /etc/systemd/system/ttyd-bash.service
```
Then rebuild the image.
## Verification
After making changes, verify the configuration:
### Check which services are listening on which ports:
```bash
sudo netstat -tlnp | grep :80
```
### Check Dangerous Pi status:
```bash
sudo systemctl status dangerous-pi
```
### Check ttyd-bash status:
```bash
sudo systemctl status ttyd-bash
```
### Test access:
```bash
# Dangerous Pi (adjust port as needed)
curl http://localhost:8000/api/health
# ttyd-bash (if enabled, adjust port as needed)
curl http://localhost:8000
```
## Recommendations
**For most users**: We recommend **Option 1** (disable ttyd-bash) because:
- Dangerous Pi provides a more comprehensive web interface
- It includes PM3 command capabilities
- Simpler configuration
- Fewer services running = better performance on Pi Zero 2 W
**For advanced users**: If you need both interfaces for specific workflows, use **Option 2** or **Option 3**.
## Troubleshooting
### Service won't start - "Address already in use"
Check which service is using the port:
```bash
sudo lsof -i :8000
```
Stop the conflicting service before starting Dangerous Pi.
### Can't access after changing port
1. Verify the service is running:
```bash
sudo systemctl status dangerous-pi
```
2. Check the port in the environment file:
```bash
grep PORT /opt/dangerous-pi/.env
```
3. Check firewall rules (if enabled):
```bash
sudo iptables -L -n
```
### Changes not taking effect
After modifying configurations, always:
```bash
# If you changed service files:
sudo systemctl daemon-reload
# Restart the service:
sudo systemctl restart dangerous-pi
```
## Future Considerations
In future versions, we may:
- Auto-detect port conflicts on startup
- Dynamically select an available port
- Provide a web-based port configuration tool
- Integrate or replace ttyd entirely
For now, manual configuration provides the most flexibility.

## API Documentation
Once the server is running, visit:
- **Swagger UI**: http://localhost:8000/docs
- **ReDoc**: http://localhost:8000/redoc
## Development Workflow
### Backend Development
1. **Add new endpoint**:
- Create/edit router in `app/backend/api/`
- Register router in `app/backend/main.py`
- Test with curl or Swagger UI
2. **Add new manager**:
- Create manager in `app/backend/managers/`
- Use in API endpoints
- Add tests
3. **Add SSE event**:
- Add helper function in `app/backend/sse/events.py`
- Call from managers/workers
- Test with `curl -N`
### Testing on Raspberry Pi
1. **Transfer code**:
```bash
rsync -avz --exclude 'venv' --exclude '__pycache__' \
. dt@10.3.141.1:/home/dt/dangerous-pi/
```
2. **SSH into Pi**:
```bash
ssh dt@10.3.141.1
```
3. **Install and run**:
```bash
cd dangerous-pi
pip3 install -r requirements.txt
python3 -m app.backend.main
```
## Mock vs Real PM3
The backend automatically uses `MockPM3Worker` when the `pm3` module is not available. This allows development without Proxmark3 hardware.
To use real PM3:
- Ensure Proxmark3 client is installed with Python support
- The `pm3` module must be importable
- Set `PM3_DEVICE` environment variable to your device path
## Environment Variables
Copy `.env.example` to `.env` and customize:
```bash
cp .env.example .env
nano .env
```
See [claude.md](claude.md) for full list of environment variables.
## Next Steps
See [claude.md](claude.md) for:
- Detailed architecture
- Implementation roadmap
- PM3 API usage
- Integration guidelines
## Troubleshooting
### Port 8000 already in use
The existing pi-pm3 uses ttyd on port 8000. Either:
- Change PORT in config to 8001
- Stop ttyd: `sudo systemctl stop ttyd-bash`
### PM3 module not found
Expected during development. The mock worker will be used automatically.
### Database locked
Stop all running instances of the backend.

# Dangerous Pi - UI/UX Guidelines
## Design Philosophy
**Resource-Constrained Excellence**: Build a beautiful, functional interface that respects the Pi Zero 2 W's limited resources while providing an excellent user experience.
### Core Principles
1. **Performance First** - Every byte counts
2. **Progressive Enhancement** - Works without JavaScript, better with it
3. **Mobile-First** - Optimize for small screens (most users access via phone)
4. **Single-Purpose Focus** - One task at a time, clear hierarchy
5. **Instant Feedback** - Users should never wonder what's happening
---
## Technical Constraints
### Hardware Limitations
- **CPU**: Quad-core ARM Cortex-A53 @ 1GHz (limited)
- **RAM**: 512MB (shared with OS and backend)
- **Network**: WiFi only, potentially slow AP mode
- **Storage**: MicroSD (minimize writes)
### Performance Targets
- **First Contentful Paint**: < 1.5s
- **Time to Interactive**: < 3s
- **Total Bundle Size**: < 150KB (gzipped)
- **CSS**: < 20KB (gzipped)
- **Fonts**: System fonts only (no web fonts)
---

├─────────────────────────────────┤
│ Bottom Nav (mobile) │
│ or Footer (desktop) │
└─────────────────────────────────┘
```
---
## Interaction Patterns
### Loading States
1. **Skeleton screens** for initial load (CSS only, no spinners)
2. **Inline progress** for actions (e.g., "Executing...")
3. **Toast notifications** for completion/errors (auto-dismiss)
### Error Handling
1. **Inline validation** - Show errors near the field
2. **Error boundaries** - Graceful degradation
3. **Retry options** - Always offer a way forward
4. **Clear messages** - Explain what happened and why
### Real-Time Updates (SSE)
1. **Status badges** - Live connection indicator
2. **Notification dot** - New events available
3. **Auto-update** - Background refresh without disruption
4. **Rate limiting** - Debounce rapid updates
### Command Execution Flow
```
1. User enters command
2. Instant visual feedback (disable button, show "Executing...")
3. Command sent to backend
4. Progress indication (if long-running)
5. Result display (success/error with output)
6. Re-enable interface
```
---
## Page Specifications

- **Color contrast**: 4.5:1 minimum for text
- **Keyboard navigation**: All interactive elements reachable
- **Focus indicators**: Clear, visible focus styles
- **ARIA labels**: Meaningful labels for screen readers
- **Alt text**: All images/icons have descriptions
### Touch Targets
- **Minimum size**: 44x44px
- **Spacing**: 8px minimum between targets
- **Feedback**: Visual response to all interactions
---
## Performance Optimization
### CSS Strategy
```
✅ DO:
- Use vanilla CSS (no framework overhead)
- CSS Grid & Flexbox for layouts
- CSS variables for theming
- Minimal animations (transform/opacity only)
- Mobile-first media queries
❌ DON'T:
- Heavy CSS frameworks (Bootstrap, Material UI)
- Web fonts (use system fonts)
- Complex animations (drains CPU)
- Excessive shadows/gradients
- Unused CSS
```
### JavaScript Strategy
```
✅ DO:
- Remix SSR (minimal client JS)
- Progressive enhancement
- Code splitting by route
- Debounce user input
- Use native APIs where possible
❌ DON'T:
- Heavy libraries (moment.js, lodash)
- Polyfills for modern browsers only
- Unnecessary dependencies
- Client-side rendering (use SSR)
- Global state (use URL/forms)
```
### Image Strategy
```
✅ DO:
- Inline SVG icons (<2KB each)
- System emoji for decorative elements
- Lazy loading for below-fold images
- Serve WebP with fallbacks
❌ DON'T:
- Icon fonts (Flash of Unstyled Text)
- Large images (compress heavily)
- Unoptimized assets
- Background images (use CSS colors)
```
---
## Dark Mode
### Implementation
- **System preference detection**: `prefers-color-scheme`
- **Manual toggle**: Persisted in localStorage
- **CSS variables**: Single source of truth for colors
- **No flash**: SSR with cookie-based preference
### Colors
```css
:root {
/* Light mode (default) */
--color-bg: #ffffff;
--color-surface: #f9fafb;
--color-text: #111827;
}
@media (prefers-color-scheme: dark) {
:root {
--color-bg: #1f2937;
--color-surface: #111827;
--color-text: #f9fafb;
}
}
```
---
## Mobile Considerations
### Touch-First Design
- Large buttons (44x44px minimum)
- Bottom navigation (thumb zone)
- Swipe gestures (optional, enhance)
- Avoid hover-only interactions
### Viewport
```html
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=5">
```
### PWA Support
- Add to home screen
- Offline fallback page
- Service worker for caching
- App manifest
---

# Update Manager - Technical Documentation
## Overview
The Update Manager provides automatic system updates from GitHub releases, including version checking, downloading, installation, and rollback capabilities.
## Architecture
### Backend Components
**Location**: `app/backend/managers/update_manager.py`
**Key Classes:**
- `UpdateManager` - Core manager class
- `UpdateStatus` - Enum for update states
- `ReleaseInfo` - Data class for GitHub release information
- `UpdateProgress` - Data class for progress tracking
### API Endpoints
**Location**: `app/backend/api/updates.py`
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/updates/check` | GET | Check for available updates |
| `/api/updates/progress` | GET | Get current update progress |
| `/api/updates/download` | POST | Download available update |
| `/api/updates/install` | POST | Install downloaded update |
| `/api/updates/release-notes` | POST | Get release notes for a version |
| `/api/updates/current-version` | GET | Get current system version |
## Features
### 1. Automatic Update Checks
Periodically checks GitHub releases API for new versions:
```python
# Configurable check interval (default: 1 hour)
UPDATE_CHECK_INTERVAL=3600
# Checks start automatically on backend startup
update_manager = get_update_manager()
await update_manager.start_periodic_checks()
```
**Detection Logic:**
- Fetches latest release from GitHub API
- Compares semantic versions (e.g., "1.2.3")
- Handles pre-release tags
- Stores last check timestamp
### 2. Version Comparison
Uses semantic versioning for comparison:
```python
def _is_newer_version(self, version1: str, version2: str) -> bool:
# Parses versions like "1.2.3" or "v1.2.3"
# Compares major.minor.patch components
# Returns True if version1 > version2
```
**Supported Formats:**
- Standard: `1.2.3`
- Prefixed: `v1.2.3`
- Pre-release: `1.2.3-beta.1` (metadata stripped for comparison)
### 3. Update Download
Downloads release assets with progress tracking:
```python
async def download_update(self) -> bool:
# Downloads to temporary directory
# Tracks progress for UI updates
# Verifies checksum if available
# Cleans up on failure
```
**Features:**
- Progress tracking (0-100%)
- Checksum verification (SHA256)
- Automatic cleanup on errors
- Configurable timeout
### 4. Installation Process
Safe installation with backup and rollback:
```python
async def install_update(self) -> bool:
# 1. Backup current installation
# 2. Extract update archive
# 3. Run post-install script
# 4. Rebuild PM3 client
# 5. Update version file
# 6. Rollback on failure
```
**Installation Steps:**
1. Create backup of `/opt/dangerous-pi`
2. Extract tar.gz archive to install directory
3. Execute `scripts/post-install.sh` if present
4. Rebuild Proxmark3 client (`make clean && make`)
5. Update VERSION file
6. Restore backup if any step fails
### 5. Update States
**State Machine:**
```
IDLE → CHECKING → AVAILABLE → DOWNLOADING → INSTALLING → COMPLETE
↓ ↓ ↓
FAILED ←────────────┴─────────────┘
```
**State Descriptions:**
- `IDLE`: No update activity
- `CHECKING`: Querying GitHub API
- `AVAILABLE`: Update ready to download
- `DOWNLOADING`: Download in progress
- `INSTALLING`: Installing update

```
**Install Update:**
```bash
curl -X POST http://localhost:8000/api/updates/install
```
### Frontend Usage
1. Navigate to Updates page
2. Click "Check for Updates"
3. Review release notes if update available
4. Click "Download Update"
5. Wait for download to complete
6. Click "Install Update"
7. Restart service when prompted
## Implementation Details
### GitHub API Integration
Uses GitHub REST API v3:
```python
# Fetch latest release
url = f"https://api.github.com/repos/{GITHUB_REPO}/releases/latest"
# Fetch specific version
url = f"https://api.github.com/repos/{GITHUB_REPO}/releases/tags/v1.0.0"
```
**Rate Limiting:**
- Unauthenticated: 60 requests/hour
- Authenticated: 5000 requests/hour
- Consider adding GitHub token for higher limits
**Release Asset Requirements:**
- Must include `.tar.gz` file
- Optional `.sha256` checksum file
- Asset naming: `dangerous-pi-{version}.tar.gz`
### Checksum Verification
SHA256 checksum validation:
```python
async def _verify_checksum(self, file_path: Path, expected: str) -> bool:
sha256 = hashlib.sha256()
with open(file_path, 'rb') as f:
while chunk := f.read(65536): # 64KB chunks
sha256.update(chunk)
return sha256.hexdigest() == expected.lower()
```
### Backup and Rollback
Automatic backup before installation:
```python
# Backup structure
/opt/dangerous-pi/ # Current installation
/opt/dangerous-pi-backup/ # Backup before update
# Rollback on failure
if installation_fails:
shutil.rmtree(install_dir)
shutil.copytree(backup_dir, install_dir)
```
### PM3 Client Rebuild
Rebuilds Proxmark3 client after updates:
```python
async def _rebuild_pm3_client(self):
pm3_dir = Path("/opt/proxmark3")
if pm3_dir.exists():
await self._run_command(
f"cd {pm3_dir} && make clean && make"
)
```
## Configuration
### Environment Variables
```bash
# Version (read from VERSION file or env)
VERSION=0.1.0
# GitHub repository
GITHUB_REPO=dangerous-things/dangerous-pi
# Update check interval (seconds)
UPDATE_CHECK_INTERVAL=3600
# Optional: GitHub token for higher rate limits
GITHUB_TOKEN=ghp_xxxxxxxxxxxxxxxxxxxx
```
### Installation Paths
```
/opt/dangerous-pi/ # Application directory
/opt/dangerous-pi/VERSION # Version file
/opt/dangerous-pi/scripts/ # Install scripts
/opt/dangerous-pi-backup/ # Backup directory
/tmp/dangerous-pi-update-*/ # Temporary download directory
```
## Security Considerations
### Verification
- **Checksum Validation**: SHA256 verification of downloads
- **HTTPS Only**: All downloads over HTTPS
- **Signed Releases**: Consider GPG signature verification (future)
### Permissions
Update operations require elevated privileges:
```bash
# Commands that need sudo:
- tar -xzf (to /opt directory)
- make (for PM3 rebuild)
- systemctl restart (for service restart)
```
**Solution**: Configure sudoers for specific commands:
```
www-data ALL=(ALL) NOPASSWD: /bin/tar
www-data ALL=(ALL) NOPASSWD: /usr/bin/make
www-data ALL=(ALL) NOPASSWD: /bin/systemctl restart dangerous-pi
```
### Backup Safety
- Backup created before every installation
- Single backup retained (consider multiple backup retention)
- Automatic rollback on installation failure
- Manual rollback possible by copying backup
## Troubleshooting
### Update Check Fails
**Symptom**: "Failed to check for updates"
**Check:**
```bash
# Test GitHub API access
curl https://api.github.com/repos/YOUR_REPO/releases/latest
# Check network connectivity
ping api.github.com
# Verify GITHUB_REPO config
echo $GITHUB_REPO
```
**Solutions:**
- Check internet connection
- Verify repository exists and is public
- Add GitHub token if rate limited
- Check firewall settings
### Download Fails
**Symptom**: Download stuck or fails
**Check:**
```bash
# Check disk space
df -h /tmp
# Check network speed
wget --spider https://github.com/releases/download/test.tar.gz
# Check download URL
curl -I [download_url]
```
**Solutions:**
- Free up disk space
- Check network connection
- Verify asset exists in release
- Increase timeout if slow connection
### Installation Fails
**Symptom**: Installation fails, system rolled back
**Check:**
```bash
# Check installation directory
ls -la /opt/dangerous-pi
# Check backup exists
ls -la /opt/dangerous-pi-backup
# Check permissions
stat /opt/dangerous-pi
# Check logs
journalctl -u dangerous-pi
```
**Solutions:**
- Verify sufficient disk space
- Check directory permissions
- Ensure backup directory is not corrupted
- Run post-install script manually to debug
### PM3 Rebuild Fails
**Symptom**: PM3 client rebuild fails during installation
**Check:**
```bash
# Check PM3 directory
ls -la /opt/proxmark3
# Try manual rebuild
cd /opt/proxmark3
make clean
make
# Check build dependencies
dpkg -l | grep build-essential
```
**Solutions:**
- Install missing build dependencies
- Check PM3 source integrity
- Run rebuild manually
- Skip rebuild if PM3 not used
## Testing
### Unit Tests
```python
# Test version comparison
assert manager._is_newer_version("1.2.0", "1.1.0") == True
assert manager._is_newer_version("1.0.0", "1.0.0") == False
assert manager._is_newer_version("2.0.0", "1.9.9") == True
# Test checksum verification
assert await manager._verify_checksum(file_path, valid_checksum) == True
assert await manager._verify_checksum(file_path, invalid_checksum) == False
```
### Integration Tests
```bash
# Test check endpoint
curl http://localhost:8000/api/updates/check
# Test download (requires available update)
curl -X POST http://localhost:8000/api/updates/download
# Test progress polling
while true; do
curl http://localhost:8000/api/updates/progress
sleep 1
done
# Test installation
curl -X POST http://localhost:8000/api/updates/install
```
### Manual Testing
1. **Fresh Check:**
- Start backend
- Verify automatic check on startup
- Check last_check timestamp
2. **Update Flow:**
- Create new release on GitHub
- Click "Check for Updates"
- Verify release notes display
- Download update
- Monitor progress bar
- Install update
- Verify version changed
3. **Failure Scenarios:**
- Test with no internet
- Test with invalid checksum
- Test with insufficient disk space
- Verify rollback works
4. **Periodic Checks:**
- Wait for automatic check (default: 1 hour)
- Verify no UI interruption
- Check last_check updates
## Performance
### Check Duration
- API request: ~200-500ms
- Version parsing: <10ms

# WiFi Manager - Technical Documentation
## Overview
The WiFi Manager provides comprehensive network management for Dangerous Pi, including interface detection, mode switching, network scanning, and connection management.
## Architecture
### Backend Components
**Location**: `app/backend/managers/wifi_manager.py`
**Key Classes:**
- `WiFiManager` - Core manager class
- `WiFiMode` - Enum for operation modes (AP, Client, Dual, Auto, Off)
- `WiFiInterface` - Data class for interface information
- `WiFiNetwork` - Data class for scanned networks
- `WiFiStatus` - Data class for current status
### API Endpoints
**Location**: `app/backend/api/wifi.py`
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/wifi/status` | GET | Get current WiFi status |
| `/api/wifi/scan` | GET | Scan for available networks |
| `/api/wifi/mode` | POST | Set WiFi operation mode |
| `/api/wifi/connect` | POST | Connect to a network |
| `/api/wifi/interfaces` | GET | List available interfaces |
## Features
### 1. Interface Detection
Automatically detects all WiFi interfaces on the system:
```python
interfaces = await wifi_manager.detect_interfaces()
```
**Detected Information:**
- Interface name (wlan0, wlan1, etc.)
- MAC address
- USB vs built-in detection
- UP/DOWN status
- Connected SSID (if any)
- IP address (if assigned)
**USB Detection:**
- Checks `/sys/class/net/{iface}/device/uevent`
- Identifies USB WiFi adapters
- Enables dual-mode support when USB adapter present
### 2. Mode Detection
Automatically determines current operating mode:
**Detection Logic:**
- **AP Mode**: Interface has IP in 10.3.141.x range
- **Client Mode**: Interface connected to network
- **Dual Mode**: Both AP and Client active
- **Auto Mode**: System choosing automatically
- **Off**: No interfaces active
### 3. Network Scanning
Scans for available WiFi networks using `iw`:
```bash
# Backend executes:
sudo iw dev wlan0 scan trigger
sudo iw dev wlan0 scan
```
**Parsed Information:**
- SSID (network name)
- BSSID (MAC address)
- Signal strength (dBm)
- Frequency (MHz)
- Encryption status (WPA/WPA2/Open)
### 4. WiFi Modes
#### Access Point (AP) Mode
- Hosts own WiFi network
- Default SSID: `raspi-webgui`
- Default IP: `10.3.141.1`
- Integrates with existing RaspAP setup
#### Client Mode
- Connects to existing WiFi network
- Receives IP via DHCP
- Single interface operation
#### Dual Mode
- **Requires USB WiFi adapter**
- Simultaneously runs AP and Client
- Built-in WiFi: Client connection
- USB WiFi: Access Point
- Enables internet sharing
#### Auto Mode
- System automatically selects best mode
- Prefers dual if available
- Falls back to client or AP
## Frontend Integration

## Usage Examples
### Backend API
**Get WiFi Status:**
```bash
curl http://localhost:8000/api/wifi/status
```
Response:
```json
{
"mode": "ap",
"interfaces": [
{
"name": "wlan0",
"mac": "b8:27:eb:12:34:56",
"is_usb": false,
"is_up": true,
"connected": false,
"ssid": null,
"ip_address": "10.3.141.1"
}
],
"current_ssid": null,
"current_ip": null,
"ap_ssid": "raspi-webgui",
"ap_ip": "10.3.141.1",
"supports_dual": false
}
```
**Scan Networks:**
```bash
curl http://localhost:8000/api/wifi/scan
```
Response:
```json
[
{
"ssid": "MyWiFi",
"bssid": "00:11:22:33:44:55",
"signal_strength": -45,
"frequency": 2437,
"encrypted": true,
"in_use": false
}
]
```
**Set Mode:**
```bash
curl -X POST http://localhost:8000/api/wifi/mode \
-H "Content-Type: application/json" \
-d '{"mode": "client"}'
```
### Frontend Usage
1. Navigate to Settings page
2. Click "Wi-Fi" tab
3. View current status
4. Select desired mode
5. Scan for networks
6. Click network to connect (coming soon)
## Implementation Details
### Interface Detection
Uses `iw dev` command to enumerate wireless interfaces:
```python
async def detect_interfaces(self) -> List[WiFiInterface]:
result = await self._run_command("iw dev")
# Parse output
# Check USB status via sysfs
# Get IP addresses via ip command
return interfaces
```
### USB Detection
Checks sysfs to determine if interface is USB:
```python
def _is_usb_interface(self, iface_name: str) -> bool:
device_path = Path(f"/sys/class/net/{iface_name}/device")
uevent_path = device_path / "uevent"
content = uevent_path.read_text()
return "usb" in content.lower()
```
### Network Scanning
Two-step process:
1. Trigger scan: `iw dev {iface} scan trigger`
2. Wait 2 seconds for scan to complete
3. Read results: `iw dev {iface} scan`
Parse output for:
- BSS (network) entries
- SSID names
- Signal levels
- Frequency information
- Security capabilities
### Mode Switching
Currently integrates with existing RaspAP:
```python
async def set_mode(self, mode: WiFiMode) -> bool:
# TODO: Implement mode switching
# Options:
# 1. Use RaspAP API
# 2. Direct NetworkManager/wpa_supplicant
# 3. Custom scripts
self._current_mode = mode
return True
```
## Integration with Existing Setup
### RaspAP Compatibility
- **Existing Setup**: RaspAP manages AP mode
- **Integration Approach**: WiFi manager detects RaspAP configuration
- **Migration Path**: Can gradually replace RaspAP features
**RaspAP Files:**
- Config: `/etc/hostapd/hostapd.conf`
- Interface: http://10.3.141.1
- User: admin / secret
### Coexistence
WiFi Manager works alongside RaspAP:
- Detects RaspAP-configured AP
- Reads hostapd.conf for AP SSID
- Allows mode switching via new API
- Maintains backward compatibility
## Future Enhancements
### Near Term
- [ ] Full mode switching implementation
- [ ] Network connection UI
- [ ] Password entry for encrypted networks
- [ ] Connection status notifications via SSE
- [ ] Auto-reconnect on disconnect
### Medium Term
- [ ] Saved networks list
- [ ] Network priority/ordering
- [ ] Forget network function
- [ ] Hidden SSID support
- [ ] Static IP configuration
### Long Term
- [ ] Complete RaspAP replacement
- [ ] VPN support (OpenVPN, WireGuard)
- [ ] Advanced AP settings (channel, power)
- [ ] MAC filtering
- [ ] Captive portal for AP mode
## Security Considerations
### Permissions
WiFi operations require elevated privileges:
```bash
# Commands that need sudo:
- iw dev scan trigger
- iw dev scan
- wpa_cli commands
- hostapd configuration changes
```
**Solution**: Configure sudoers for specific commands:
```
www-data ALL=(ALL) NOPASSWD: /sbin/iw
www-data ALL=(ALL) NOPASSWD: /usr/sbin/wpa_cli
```
### Password Handling
- Passwords never logged
- Stored securely in wpa_supplicant conf
- Transmitted over HTTPS (when enabled)
- Not included in API responses
### Access Control
- Optional authentication required
- Session-based access
- Rate limiting on scan requests
- Network operations logged
## Troubleshooting
### Interface Not Detected
**Symptom**: No interfaces shown in status
**Check:**
```bash
# List interfaces
iw dev
# Check if up
ip link show wlan0
# Bring up if needed
sudo ip link set wlan0 up
```
### Scan Fails
**Symptom**: Empty network list
**Check:**
```bash
# Try manual scan
sudo iw dev wlan0 scan
# Check permissions
ls -l /sys/class/net/wlan0
# Check rfkill
rfkill list
```
### USB WiFi Not Detected
**Symptom**: Dual mode not available
**Check:**
```bash
# List USB devices
lsusb
# Check kernel modules
lsmod | grep 80211
# Check dmesg for errors
dmesg | grep wlan
```
### Mode Switch Fails
**Symptom**: Mode doesn't change
**Check:**
- RaspAP is running: `systemctl status raspapd`
- hostapd configuration: `/etc/hostapd/hostapd.conf`
- wpa_supplicant status: `wpa_cli status`
## Testing
### Unit Tests
```python
# Test interface detection
interfaces = await wifi_manager.detect_interfaces()
assert len(interfaces) > 0
# Test USB detection
is_usb = wifi_manager._is_usb_interface("wlan1")
assert is_usb == True
# Test mode detection
mode = await wifi_manager._detect_current_mode()
assert mode in [WiFiMode.AP, WiFiMode.CLIENT, WiFiMode.DUAL]
```
### Integration Tests
```bash
# Test API endpoints
curl http://localhost:8000/api/wifi/status
curl http://localhost:8000/api/wifi/scan
curl -X POST http://localhost:8000/api/wifi/mode -d '{"mode":"ap"}'
```
### Manual Testing
1. Connect USB WiFi adapter
2. Reload page, check "Dual Mode Support" is "Available"
3. Click "Scan for Networks"
4. Verify networks appear with signal strength
5. Test mode switching buttons
## Performance
### Scan Duration
- Trigger: < 100ms
- Completion: ~2 seconds
- Parse: < 50ms
- **Total**: ~2.2 seconds
### Interface Detection
- Command execution: < 200ms
- Parsing: < 50ms
- **Total**: < 300ms
### Status Check
- Multiple commands: ~500ms
- **Total**: < 1 second

# Dangerous Pi Frontend
Modern, lightweight web interface for Proxmark3 management built with Remix.js.
## Features
- **Cyberpunk Theme** - Dark mode default with light mode support
- **Responsive Design** - Mobile-first, works on all screen sizes
- **Real-time Updates** - SSE integration for live status
- **Lightweight** - Optimized for Pi Zero 2 W (< 150KB bundle)
- **Progressive Enhancement** - Works without JavaScript
## Tech Stack
- **Framework**: Remix v2 (React Router)
- **Styling**: Vanilla CSS (no framework, ~15KB)
- **Build**: Vite
- **TypeScript**: Full type safety
## Development
### Prerequisites
- Node.js 18+
- npm or yarn
- Backend running on http://localhost:8000
### Install Dependencies
```bash
npm install
```
### Start Development Server
```bash
npm run dev
```
Frontend will be available at http://localhost:3000
The dev server proxies API requests to the backend (http://localhost:8000).
### Build for Production
```bash
npm run build
```
### Start Production Server
```bash
npm start
```
## Project Structure
```
app/
├── routes/ # Page routes
│ ├── _index.tsx # Dashboard (/)
│ ├── commands.tsx # PM3 Commands (/commands)
│ ├── settings.tsx # Settings (/settings)
│ └── logs.tsx # Command Logs (/logs)
├── root.tsx # Root layout
├── styles.css # Global styles
└── entry.*.tsx # Client/Server entry points
```
## Pages
### Dashboard (`/`)
- System status (CPU, memory, disk)
- PM3 connection status
- Quick actions
- Real-time SSE updates
### Commands (`/commands`)
- Execute PM3 commands
- Quick command buttons
- Terminal-style output
- Command history with ↑/↓ navigation
### Settings (`/settings`)
- General settings (auth, HTTPS)
- Wi-Fi configuration
- Advanced options (PM3 device, BLE)
- System actions (restart, shutdown)
### Logs (`/logs`)
- Command history table
- Export functionality (planned)
- System logs (planned)
## Design System
### Colors (Cyberpunk)
- **Primary**: Cyan (`#00ffff`)
- **Secondary**: Magenta (`#ff00ff`)
- **Accent**: Green (`#00ff88`)
- **Background**: Dark Blue (`#0a0e1a`)
### Typography
- **Sans**: System font stack (zero download)
- **Mono**: SF Mono, Monaco, Cascadia Code, etc.
### Components
- Buttons (primary, secondary, danger)
- Cards with hover effects
- Status badges with pulse animation
- Terminal-style code blocks
- Toast notifications
- Form inputs with focus states
## Theme System
Supports three modes:
- **dark** - Cyberpunk dark theme (default)
- **light** - Clean light theme
- **auto** - Follow system preference
Theme persisted in localStorage, toggled via header button.
## API Integration
### REST Endpoints
```typescript
// System
GET /api/health
GET /api/system/info
POST /api/system/session/create
GET /api/system/config
// PM3
GET /api/pm3/status
POST /api/pm3/command
GET /api/pm3/commands/history
```
### SSE Events
```typescript
GET /sse/events
// Events:
- connected
- pm3_status
- update_available
- backup_complete
- ups_battery
```
## Performance Optimization
### Targets
- First Contentful Paint: < 1.5s
- Time to Interactive: < 3s
- Bundle Size: < 150KB gzipped
### Techniques
- Server-side rendering (SSR)
- CSS-only animations
- System fonts (no web fonts)
- Code splitting by route
- Minimal dependencies
## Accessibility
- WCAG 2.1 AA compliant
- Keyboard navigation
- Focus indicators
- ARIA labels
- Screen reader tested
## Testing Checklist
- [ ] Works without JavaScript
- [ ] Mobile responsive (320px+)
- [ ] Dark/light mode toggle
- [ ] SSE connection
- [ ] Command execution
- [ ] Session management
- [ ] Keyboard shortcuts
- [ ] Touch targets (44x44px)
## Browser Support
- Chrome/Edge 90+
- Firefox 88+
- Safari 14+
- Mobile browsers (iOS 14+, Android 10+)
## Deployment
### With Backend
The frontend should be built and served by the backend in production:
```bash
# Build frontend
cd app/frontend
npm run build
# Backend serves from build/client/
```
### Standalone (Development)
For development, run separately:
```bash
# Terminal 1: Backend
python -m app.backend.main
# Terminal 2: Frontend
cd app/frontend
npm run dev
```

# Dangerous Pi - Development Guide for Claude
## Project Overview
Dangerous Pi is a modern web-based management interface for the Proxmark3 RFID research tool, designed to run on a Raspberry Pi Zero 2 W. It extends the existing pi-pm3 project with advanced features and a Python/FastAPI backend.
## Architecture
### Backend (Python + FastAPI)
- **Location**: `/app/backend/`
- **Framework**: FastAPI with async support
- **Database**: SQLite (aiosqlite)
- **Transport**: REST + Server-Sent Events (SSE)
### Frontend (Remix or SPA)
- **Location**: `/app/frontend/`
- **Framework**: TBD - Remix (preferred) or minimal SPA
- **Transport**: REST API + SSE for notifications
### Key Components
1. **PM3 Worker** (`workers/pm3_worker.py`)
- Uses built-in `pm3` Python module from RfidResearchGroup/proxmark3
- API: `pm3.open(device)` and `.cmd(command)`
- Handles async command execution
- Single-threaded, sequential command processing
2. **Session Manager** (`managers/session_manager.py`)
- Single active session enforcement
- Takeover mechanism for new sessions
- Idle timeout (default: 5 minutes)
3. **Update Manager** (`managers/update_manager.py`)
- Polls GitHub Releases API
- Downloads and applies updates
- Rebuilds PM3 client after updates
- SSE notifications for update status
4. **Wi-Fi Manager** (`managers/wifi_manager.py`)
- Detects available interfaces (wlan0, wlan1)
- Manages modes: AP, Client, Auto, Dual (client+AP)
- Integrates with existing RaspAP setup initially
5. **UPS Manager** (`managers/ups_manager.py`)
- I2C battery monitoring
- Safe shutdown triggers
- Battery percentage reporting
6. **BLE Manager** (`managers/ble_manager.py`)
- Uses built-in Pi Zero 2 W Bluetooth
- Sends notifications for updates, backups, low battery
- Auto-detects BLE capability
## Proxmark3 Python API
The RfidResearchGroup/proxmark3 (iceman fork) includes SWIG-based Python bindings:
```python
# Standalone mode (for our backend)
import pm3
device = pm3.open("/dev/ttyACM0")
result = device.cmd("hw status")
```
**Important Notes:**
- PM3 does NOT support streaming responses
- Most commands complete and return full output
- Use REST endpoints for commands
- Use SSE only for backend-to-frontend notifications
## Current Status
### ✅ Completed (MVP Features)
- **Backend Foundation**
- FastAPI application with async support
- SQLite database (sessions, config, crash_reports, command_history)
- Health check endpoints
- Configuration management
- PM3 worker with built-in pm3 module integration
- Mock PM3 worker for development
- Session manager (single-user with takeover)
- SSE endpoints for real-time notifications
- **WiFi Manager (Full MVP)**
- Interface detection (USB vs built-in)
- Network scanning with signal strength
- Full mode switching (AP/Client/Dual/Auto/Off)
- Network connection with password support
- Hidden SSID support
- Saved networks management
- Forget network functionality
- Static IP configuration
- DHCP management
- 10 WiFi API endpoints
- **Frontend (Complete)**
- Cyberpunk-themed responsive UI
- Dashboard with system status
- PM3 command interface
- Settings with WiFi management
- Command logs
- Connection dialog with password input
- Saved networks UI
- Theme toggle (Dark/Light/Auto)
### ✅ Update Manager (Complete)
- GitHub releases API integration
- Automatic periodic update checks (configurable interval)
- Version comparison (semantic versioning)
- Update download with progress tracking
- Checksum verification (SHA256)
- Automatic installation with backup
- PM3 client rebuild after updates
- Rollback on installation failure
- 6 Update API endpoints
- Frontend UI with release notes and progress tracking
### 📋 Remaining Features
1. UPS monitoring daemon
2. BLE notification system
3. Plugin framework -- planned appstore + intergration later
4. Create systemd services
5. Update pi-gen stage to install Dangerous Pi
## Development Guidelines
### Code Style
- Use async/await throughout
- Type hints on all functions
- Docstrings for all modules and classes
- Keep functions focused and simple
### API Design
- REST for all client-initiated actions
- SSE for server-initiated notifications
- Clear error messages with appropriate status codes
- Consistent response format
### Security
- Run services as non-root user
- Optional authentication (configurable)
- Optional HTTPS (self-signed cert)
- Input validation on all endpoints
- No secrets in code (use environment variables)
### Testing Strategy
- Test endpoints with curl before building frontend
- Mock PM3 module for testing without hardware
- Test on actual Pi Zero 2 W for performance

## Integration with Existing pi-pm3
The existing pi-pm3 project provides:
- Custom Raspberry Pi OS image (pi-gen based)
- RaspAP (PHP-based WiFi management on port 80)
- ttyd web terminals (bash on 8000, pm3 on 8080)
- PM3 client built and installed
Dangerous Pi will:
- Keep RaspAP initially, potentially replace later
- Replace ttyd terminals with web UI
- Add FastAPI backend on port 8000 (conflicts with ttyd-bash)
- Update pi-gen stage to install new application
## Next Steps for Implementation
1. **Complete core backend**:
- PM3 worker with actual pm3 module integration
- Session manager with proper locking
- SSE event system for notifications
2. **Add system management**:
- Wi-Fi detection and mode switching
- Update manager with GitHub integration
- UPS monitoring daemon
3. **Build frontend**:
- Decide: Remix vs minimal SPA
- Dashboard with status indicators
- Command interface (simpler than full terminal)
- Settings pages
4. **Create installer**:
- Update pi-gen stage scripts
- Create systemd service units
- Handle port conflicts with existing ttyd

Dangerous Pi — Architecture & Dev Plan (Updated)
1. Overview
Dangerous Pi extends the existing pi-pm3
project with:
Modern web UI (Remix optional, Python + SSE preferred for efficiency)
Single-user session management with web terminal fallback
Automatic application updates via GitHub Releases
Proxmark3 client rebuild on boot
UPS / safe power management
Wi-Fi / AP management (auto / captive portal / dual Wi-Fi detection)
Optional authentication
Backup plugin scaffolding
BLE notifications using built-in Pi Zero 2 W Bluetooth
Target hardware: Raspberry Pi Zero 2 W
2. Hardware Architecture
Component Purpose Notes
Pi Zero 2 W Main controller Runs backend & web UI; includes built-in Bluetooth 4.2 (BLE)
UPS HAT Safe shutdown / battery monitoring Expose battery % via I2C or API
PNP transistor Programmatically “press” proxmark button 50–100ms pulse to emulate press
2x Slide switches Hardware mode switches One: On/Off → safe shutdown, Two: Wi-Fi → Auto/AP
Optional USB Wi-Fi dongle Enables dual Wi-Fi mode Detected dynamically; allows client + AP mode
Proxmark3 NFC/LF hardware Interfaced via Python wrapper (client/proxmark3.py)
3. Backend Architecture
3.1 Stack
Language: Python 3.11+
Framework: FastAPI (async, SSE support)
Database: SQLite (for config, crash reports, session info)
Job Queue: Async queue for Proxmark commands + rebuild tasks
System services: Systemd units for:
Backend FastAPI server
Rebuild on boot / auto-update
UPS monitoring daemon
3.2 Components
API Layer
REST endpoints for:
Triggering proxmark commands
Changing Wi-Fi mode (auto/AP/client/dual)
Initiating backup
Updating auth config
SSE endpoints for:
Notifications (update available, backup complete, PM3 rebuild required)
Command completion messages
Proxmark Worker
Python async task runner
Uses client/proxmark3.py wrapper
Fire-and-wait commands (no live streaming)
Handles one active session at a time
Arbitrates web terminal vs web UI commands
Update Manager
Polls GitHub Releases API
Downloads latest release archive
Overwrites Dangerous Pi app code + rebuilds proxmark client
Restarts backend
SSE notifies user of:
Available update
Download progress
Rebuild pending restart
Option to restart immediately
Backup Plugin Scaffold
Default: periodic full application directory backup (config + logs + scripts)
Optional: full SD image backup
User notified via SSE & BLE
Plugin can optionally push backups to file storage service
Session Manager
Only one session allowed at a time
Force takeover option in web UI
Graceful disconnect handling (releases lock)
Optional idle timeout (default: 5min)
BLE Manager
Uses built-in Pi Zero 2 W Bluetooth
Detects BLE functionality at runtime
Handles notifications for:
Updates available
Backups completed
PM3 rebuild pending
UPS low battery
Wi-Fi Detection
On boot, backend detects available network interfaces:
Built-in Wi-Fi → client / AP / auto mode
USB Wi-Fi → enables dual Wi-Fi (client + AP) mode
Web UI only exposes viable modes depending on detected hardware
4. Frontend Architecture
4.1 Stack
Framework: Remix (preferred) or minimal SPA
Transport:
SSE for server → client notifications
REST for client → server commands
Components:
Dashboard: status, UPS %, Wi-Fi mode, battery, logs, available updates
Scan: antenna placement overlay (SVG)
Clone: step-by-step wizard (MIFARE Classic, LF → T5577)
Terminal: xterm.js-based web terminal
Settings: auth, BLE pairing, backup options, SSL toggle
Wi-Fi Settings: dynamically show only available modes (auto, AP, client, client+AP if second module detected)
4.2 Design Patterns
SSR (server-side rendering) where possible to reduce Pi load
Islands/hydration only for dynamic components (terminal, wizards, notifications)
Minimal external JS libraries to keep bundles small
5. Networking / Wi-Fi
Mode Description
AP (captive portal) Forced by hardware switch; default IP: 10.3.141.1; simple portal page
Auto UI chooses mode: client / dual (if second Wi-Fi detected) / BLE / client+BLE / off
Client + BLE Only available if BLE dongle is present
Authentication Optional; user can enable password in web UI
Optional HTTPS: self-signed certificate generated at first boot if enabled
6. UPS / Power Management
UPS daemon monitors battery, triggers safe shutdown
Web UI shows battery %, UPS health, charge status
Hardware On/Off switch triggers systemd shutdown sequence
Optional PNP transistor to safely trigger proxmark button
7. Update & Rebuild Flow
On boot:
Backend service starts
Update manager checks GitHub Releases
If new release available, download + overwrite app code
Rebuild proxmark3 client using native compiler
SSE notifies user: “PM client rebuild will occur on restart”
User can choose “restart now” or defer
On update failure:
Rollback to previous working directory (retain backups)
SSE alert to user
8. Backup & Recovery
Periodic: full application directory backup by default
Optional: full SD image backup
User notifications: web UI + BLE
Restore:
UI button triggers restoration from last backup
Optional plugin can extend cloud storage
Installer: full custom OS image preconfigured for appliance mode
9. OS / Installer Layout

10. Security
Local network only (LAN)
Optional password authentication
Optional HTTPS (self-signed cert)
Backend and worker run as non-root user
Crash/error reports opt-in
11. Development / Performance Notes
FastAPI async endpoints to minimize Pi Zero 2 W CPU load
SSR for static pages, dynamic islands for interactive features
SQLite chosen for small-footprint persistence
xterm.js terminal uses a single PTY; session management prevents concurrent conflicts
Minimal JS and CSS bundles to preserve performance
PM3 commands handled asynchronously, sequentially, single-threaded
BLE automatically enabled if built-in Bluetooth functional
Dual Wi-Fi UI dynamically reflects detected hardware
12. Optional Future Plugins
Cloud backup / restore

# Dangerous Pi - pi-gen Stage Integration
This directory contains the pi-gen stage scripts for installing Dangerous Pi into the custom Raspberry Pi OS image.
## Files
- `00-run.sh` - Pre-chroot script that prepares application files
- `00-run-chroot.sh` - Chroot script that installs Dangerous Pi and dependencies
## What Gets Installed
The stage performs the following actions:
### 1. Python Dependencies
Installs all required Python packages via pip:
- FastAPI and Uvicorn (web framework and ASGI server)
- AsyncIO libraries (aiosqlite, aiohttp)
- Pydantic (data validation)
- SSE-Starlette (Server-Sent Events)
- psutil (system monitoring)
- smbus2 (I2C communication for UPS)
### 2. Application Installation
- Creates `/opt/dangerous-pi` directory
- Copies application files (backend, frontend, plugins)
- Creates data and logs directories
- Sets proper ownership (pi:pi)
### 3. Configuration
- Creates environment file from template at `/opt/dangerous-pi/.env`
- Configures default settings (can be customized post-install)
### 4. Systemd Service
- Installs systemd service unit
- Enables service to start on boot
- Configures service with security hardening
### 5. Hardware Access
- Enables I2C interface in `/boot/config.txt` (for UPS HAT)
- Adds `pi` user to hardware groups:
- `i2c` - I2C bus access
- `bluetooth` - Bluetooth access
- `gpio` - GPIO pin access
- `dialout` - Serial device access (for Proxmark3)
## Build Process
During the pi-gen build:
1. `00-run.sh` executes outside the chroot:
- Copies application files to temporary location
- Prepares directory structure
2. `00-run-chroot.sh` executes inside the chroot:
- Installs Python dependencies
- Copies files to `/opt/dangerous-pi`
- Configures system
- Installs and enables systemd service
## Integration with Existing pi-pm3 Stages
Dangerous Pi (stage 04) runs after:
- Stage 01: Proxmark3 installation
- Stage 02: RaspAP installation
- Stage 03: ttyd installation
This order ensures all dependencies are available.
## Port Conflict Handling
The ttyd-bash service (from stage 03) uses port 8000, which conflicts with Dangerous Pi's default port. See the port conflict handling task for resolution options.
## Post-Build Configuration
After the image is built and booted, you can customize:
1. Edit `/opt/dangerous-pi/.env` to configure settings
2. Restart service: `sudo systemctl restart dangerous-pi`
3. View status: `sudo systemctl status dangerous-pi`
4. View logs: `sudo journalctl -u dangerous-pi -f`
## Testing the Stage
To test this stage during development:
1. Make changes to Dangerous Pi code
2. Run pi-gen build (this stage will copy the latest code)
3. Flash image to SD card
4. Boot Raspberry Pi
5. Check service status
## Customization
### Change Installation Directory
Edit `00-run-chroot.sh`:
```bash
mkdir -p /your/custom/path
cd /your/custom/path
```
Also update the systemd service file paths.
### Add Additional Dependencies
Edit `00-run-chroot.sh` and add to the pip install command:
```bash
pip3 install --break-system-packages \
<existing packages> \
your-new-package==1.0.0
```
### Skip Service Auto-Start
Comment out or remove from `00-run-chroot.sh`:
```bash
# systemctl enable dangerous-pi.service
```
## Troubleshooting
### Build Fails - Python Package Error
Check that all package versions in the pip install command match `requirements.txt`.
### Build Fails - Permission Error
Ensure scripts are executable:
```bash
chmod +x 00-run.sh 00-run-chroot.sh
```
### Service Doesn't Start After Boot
Check systemd logs:
```bash
sudo journalctl -u dangerous-pi -b
```
Common issues:
- Missing dependencies
- Incorrect file permissions
- Port conflict with ttyd
- Missing environment variables
### I2C Not Working
Verify I2C is enabled:
```bash
grep i2c_arm /boot/config.txt
ls -l /dev/i2c*
```
### Can't Access Proxmark3
Verify user is in dialout group:
```bash
groups pi | grep dialout
ls -l /dev/ttyACM*
```
## Development Workflow
1. Make changes to Dangerous Pi code in main repository
2. Test locally with `python3 -m app.backend.main`
3. When ready to test in image:
- Run pi-gen build (or incremental build for this stage)
- Flash to SD card and test
4. Iterate as needed
## Version Management
The VERSION file is copied from the repository root. If it doesn't exist, version defaults to "0.1.0".
To set a specific version:
```bash
echo "1.0.0" > /path/to/dangerous-pi/VERSION
```
Then rebuild the image.

# Dangerous Pi Systemd Service
This directory contains systemd service files and installation scripts for running Dangerous Pi as a system service.
## Files
- `dangerous-pi.service` - Main systemd service unit file
- `dangerous-pi.env.example` - Environment configuration template
- `install-service.sh` - Installation script
- `uninstall-service.sh` - Uninstallation script
## Installation
### Automated Installation
Run the installation script as root:
```bash
cd /path/to/dangerous-pi/systemd
sudo ./install-service.sh
```
This will:
1. Copy the service file to `/etc/systemd/system/`
2. Create the environment configuration file at `/opt/dangerous-pi/.env`
3. Create data and logs directories
4. Add the `pi` user to required hardware access groups
5. Enable the service to start on boot
### Manual Installation
If you prefer to install manually:
```bash
# Copy service file
sudo cp dangerous-pi.service /etc/systemd/system/
# Copy environment template
sudo cp dangerous-pi.env.example /opt/dangerous-pi/.env
# Create directories
sudo mkdir -p /opt/dangerous-pi/data /opt/dangerous-pi/logs
sudo chown -R pi:pi /opt/dangerous-pi/data /opt/dangerous-pi/logs
# Add pi user to groups
sudo usermod -a -G i2c,bluetooth,gpio,dialout pi
# Reload systemd and enable service
sudo systemctl daemon-reload
sudo systemctl enable dangerous-pi
```
## Configuration
Edit the environment file to customize your installation:
```bash
sudo nano /opt/dangerous-pi/.env
```
Available configuration options:
- `PM3_DEVICE` - Proxmark3 device path (default: `/dev/ttyACM0`)
- `PM3_TIMEOUT` - PM3 command timeout in seconds
- `SESSION_TIMEOUT` - User session timeout in seconds
- `HOST` - Server bind address (default: `0.0.0.0`)
- `PORT` - Server port (default: `8000`)
- `GITHUB_REPO` - GitHub repository for updates
- `UPS_I2C_ADDRESS` - I2C address for UPS HAT
- `BLE_ENABLED` - Enable/disable BLE notifications
- `AUTH_ENABLED` - Enable/disable authentication
- See `dangerous-pi.env.example` for all options
## Service Management
### Start the service
```bash
sudo systemctl start dangerous-pi
```
### Stop the service
```bash
sudo systemctl stop dangerous-pi
```
### Restart the service
```bash
sudo systemctl restart dangerous-pi
```
### Check service status
```bash
sudo systemctl status dangerous-pi
```
### View service logs
```bash
# View recent logs
sudo journalctl -u dangerous-pi
# Follow logs in real-time
sudo journalctl -u dangerous-pi -f
# View logs since boot
sudo journalctl -u dangerous-pi -b
```
### Enable service (start on boot)
```bash
sudo systemctl enable dangerous-pi
```
### Disable service (don't start on boot)
```bash
sudo systemctl disable dangerous-pi
```
## Uninstallation
Run the uninstallation script as root:
```bash
cd /path/to/dangerous-pi/systemd
sudo ./uninstall-service.sh
```
This will:
1. Stop the service if running
2. Disable the service
3. Remove the service unit file
4. Reload systemd daemon
Note: Application files in `/opt/dangerous-pi` are NOT removed automatically.
## Security Features
The service includes security hardening:
- Runs as non-root user (`pi`)
- Private `/tmp` directory
- Protected system directories
- Read-only application directory (except for `data` and `logs`)
- Resource limits (memory, CPU, file descriptors)
- No new privileges allowed
## Hardware Access
The service is configured to access the following hardware:
- I2C devices (for UPS HAT) via `i2c` group
- Bluetooth (for BLE notifications) via `bluetooth` group
- GPIO pins via `gpio` group
- Serial devices (for Proxmark3) via `dialout` group
## Troubleshooting
### Service fails to start
Check the logs for errors:
```bash
sudo journalctl -u dangerous-pi -n 50
```
### Permission denied errors
Ensure the `pi` user is in the required groups:
```bash
groups pi
```
Should include: `i2c`, `bluetooth`, `gpio`, `dialout`
### Port already in use
The default port (8000) conflicts with ttyd-bash from pi-pm3. See the main README for resolution options.
### Can't access Proxmark3
Ensure the PM3 device path is correct in `/opt/dangerous-pi/.env`:
```bash
PM3_DEVICE=/dev/ttyACM0
```
Check that the device exists:
```bash
ls -l /dev/ttyACM*
```
## Advanced Configuration
### Custom Installation Directory
To use a different installation directory, edit the service file before installation:
```bash
WorkingDirectory=/your/custom/path
ReadWritePaths=/your/custom/path/data /your/custom/path/logs
```
### Different User/Group
To run as a different user, edit the service file:
```bash
User=your-user
Group=your-group
```
Don't forget to add the user to required hardware groups.
### Resource Limits
Adjust resource limits in the service file:
```bash
MemoryMax=1G # Maximum memory
CPUQuota=100% # CPU usage limit
LimitNOFILE=131072 # Max open files
```
## Integration with pi-pm3
When running alongside the existing pi-pm3 setup:
1. **Port Conflict**: Port 8000 is used by ttyd-bash. Options:
- Change Dangerous Pi port in `.env`: `PORT=8001`
- Disable ttyd-bash: `sudo systemctl disable ttyd-bash`
2. **RaspAP Compatibility**: Dangerous Pi WiFi manager can coexist with RaspAP or replace it.
3. **PM3 Access**: Only one service should access PM3 at a time. Disable ttyd-pm3 if using Dangerous Pi's PM3 interface.
