✨ Features

• 🚀 One-Command Setup - Install and configure in seconds
• 📱 Multi-Device Support - Manage multiple Android devices simultaneously
• 🔐 Secure Tunneling - API key-based authentication via NativeBridge
• 🌍 Remote Access - Access devices from anywhere in the world
• 🤖 Auto-Installation - Automatically installs bore tunnel and ADB
• 💻 Cross-Platform - Works on macOS, Linux, and Windows
• 🔄 Background Management - Tunnels run in the background as daemons
• 🔍 Automatic Health Monitoring - Auto-detects and deactivates disconnected devices (5s polling)
• 📊 Device Tracking - Track device state and connection URLs in real-time
• ✅ Input Validation - Validates device serials via ADB before backend calls

🚀 Quick Start

1. Install BridgeLink

pip install bridgelink

2. Install Dependencies

bridgelink install

This automatically installs:

• bore - Tunnel binary for your platform (macOS, Linux, Windows)
• ADB - Android Debug Bridge from Google

3. Set API Key

Get your API key from NativeBridge Dashboard:

export NB_API_KEY='Nb-kNGB.your-api-key-here'

4. Connect Your Device

Connect your Android device via USB and enable USB debugging.

5. Add Device

bridgelink devices add <device-serial>

6. Access Remotely

adb connect bridgelink.nativebridge.io:15750

📋 Commands

Device Management

# Add device(s)
bridgelink devices add <serial>
bridgelink devices add <serial1> <serial2>  # Multiple devices

# Activate existing device
bridgelink devices activate <serial>

# List all devices
bridgelink devices list

# Deactivate device (keeps registration)
bridgelink devices deactivate <serial>
bridgelink devices deactivate              # Deactivate ALL active devices (with confirmation)
bridgelink devices deactivate --all        # Deactivate ALL active devices

# Remove device completely
bridgelink devices remove <serial>

Daemon Management

# Check tunnel status
bridgelink daemon status

# View tunnel logs
bridgelink daemon logs <serial>

# Stop tunnel(s)
bridgelink daemon stop <serial>            # Stop specific tunnel
bridgelink daemon stop                     # Stop ALL tunnels (with confirmation)
bridgelink daemon stop --all               # Stop ALL tunnels

# Clean up dead tunnels
bridgelink daemon cleanup

Installation

# Install both bore and ADB
bridgelink install

# Install only bore
bridgelink install --bore-only

# Install only ADB
bridgelink install --adb-only

🔍 Automatic Health Monitoring

BridgeLink includes automatic background health monitoring that runs seamlessly without any manual intervention.

How It Works

1. Auto-Start: When you add the first device, a background daemon automatically starts
2. Continuous Monitoring: Checks device connectivity every 5 seconds
3. Smart Detection:
   • Physical Devices: Must be in "device" state (strict)
   • Emulators: Can be in "device" or "offline" state (lenient)
4. Auto-Cleanup: When devices disconnect, automatically:
   • Stops the tunnel
   • Updates backend state to "inactive"
   • No stale connections!
5. Auto-Stop: When all devices are deactivated, the daemon automatically stops

What This Means for You

✅ No Manual Monitoring - Everything happens automatically ✅ Fast Detection - Disconnects detected within 5 seconds ✅ Clean State - No stale tunnels or active states ✅ Zero Maintenance - Daemon manages itself

Example Flow

# 1. Add a device
$ bridgelink devices add emulator-5554
🔍 Starting background health monitor...
   ✅ Health monitor started
💡 Health monitoring is active - disconnected devices will be auto-deactivated

# 2. Device gets physically disconnected
#    (Background daemon automatically detects and deactivates)
#    Logs to ~/.bridgelink/monitor.log:
#    ⚠️  Device emulator-5554 is unhealthy: Device disconnected
#       Stopping tunnel...
#       Updating backend state to inactive...
#    ✅ Device emulator-5554 deactivated successfully

# 3. Deactivate last device
$ bridgelink devices deactivate emulator-5554
🔍 No active devices remaining, stopping health monitor...
   ✅ Health monitor stopped

Daemon Location

• PID File: ~/.bridgelink/monitor.pid
• Log File: ~/.bridgelink/monitor.log
• State File: ~/.bridgelink/health_monitor.json
