# Or with sudo if permission denied:
sudo pip install bridgelink

# Windows (run terminal as Administrator)
pip install bridgelink

After installation, run setup:

bridgelink setup

This automatically installs required tools:

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

🚀 Quick Start

After installation, follow these steps:

1. Set API Key

Get your API key from NativeBridge Dashboard:

macOS / Linux:

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

Windows (Command Prompt):

set NB_API_KEY=Nb-kNGB.your-api-key-here

Windows (PowerShell):

$env:NB_API_KEY="Nb-kNGB.your-api-key-here"

2. Connect Your Device

Option A: USB Connection (Default) Connect your Android device via USB and enable USB debugging.

Option B: WiFi Connection (Wireless)

1. Connect your Android device via USB first
2. Ensure both device and computer are on the same WiFi network
3. Use the --wifi flag when adding the device (see below)

3. Add Device

USB Connection:

bridgelink devices add <device-serial>

WiFi Connection:

bridgelink devices add <device-serial> --wifi

After WiFi setup completes, you can disconnect the USB cable. The device will remain accessible via WiFi!

4. Access Remotely

Option A: Via ADB Command Line

adb connect bridgelink.nativebridge.io:15750

Option B: Via NativeBridge Dashboard Visit the BridgeLink Dashboard to:

• 📊 View all your registered devices

bridgelink setup

# Install both bore and ADB (non-interactive)
bridgelink install

# Install only bore
bridgelink install --bore-only

# Install only ADB

📡 WiFi Connection (Wireless ADB)

BridgeLink supports wireless ADB connections via WiFi, allowing you to use your devices without USB cables!

How It Works

1. Initial Setup (USB Required):

   • Connect device via USB
   • Run: bridgelink devices add <serial> --wifi
   • BridgeLink will:
     • Enable TCP/IP mode on the device (port 5555)
     • Get the device's WiFi IP address
     • Connect via WiFi (adb connect <ip>:5555)
     • Create tunnel using WiFi connection

2. After Setup:

   • Disconnect the USB cable
   • Device remains connected via WiFi
   • Tunnel continues working wirelessly
   • Access remotely via BridgeLink URL

Requirements

• Device and computer must be on the same WiFi network
• WiFi must be enabled on the Android device
• USB connection required only for initial setup

Example Usage

# Initial setup (USB connected)
bridgelink devices add 1d752b81 --wifi

# Output:
# 📡 Setting up WiFi connection...
#    Step 1/3: Enabling TCP/IP mode on device...
#    ✓ TCP/IP mode enabled on port 5555
#    Step 2/3: Getting device IP address...
#    ✓ Device IP address: 192.168.1.15
#    Step 3/3: Connecting to device via WiFi...
#    ✓ Connected via WiFi: 192.168.1.15:5555
#
# 💡 You can now disconnect the USB cable!

# Now disconnect USB - device stays connected via WiFi!
# Tunnel URL: bridgelink.nativebridge.io:15750

Multiple WiFi Devices

You can connect multiple devices via WiFi simultaneously:

# Add first device via WiFi
bridgelink devices add device1_serial --wifi

# Add second device via WiFi
bridgelink devices add device2_serial --wifi

# List all devices
bridgelink devices list
# Shows both devices with WiFi connections (IP:5555 format)

WiFi + Auto-Activation

Combine WiFi with auto-activation for ultimate convenience:

bridgelink devices add <serial> --wifi --auto-activate

Now your device will:

• ✅ Connect wirelessly via WiFi
• ✅ Auto-deactivate when disconnected from WiFi
• ✅ Auto-activate when reconnected to WiFi
• ✅ No USB cable needed after initial setup

Limitations & Notes

• Reboot: If you restart the device, it will reset to USB mode. You'll need to run the WiFi setup again (USB cable + --wifi flag).
• Network: Device and computer must remain on the same WiFi network
• Battery: WiFi ADB consumes more battery than USB ADB
• Performance: WiFi connection may have slightly higher latency than USB

Troubleshooting WiFi

Device not connecting?

# Check device IP manually
adb shell ip route | grep src

# Try manual connection
adb connect <device-ip>:5555

# Verify connection
adb devices

Connection lost?

• Ensure device hasn't gone to sleep (keep screen on during setup)
• Check both devices are on same WiFi network
• Try reconnecting: adb connect <ip>:5555

🔍 Automatic Health Monitoring & Auto-Activation

BridgeLink includes two automatic background monitors that work together to provide a fully automated device lifecycle:

1. Health Monitor (Auto-Deactivation)

Watches for disconnections and automatically deactivates devices

1. Auto-Start: When you add the first device, a background daemon automatically starts
2. Continuous Monitoring: Checks device connectivity every 1 second (fast!)
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

2. Connection Monitor (Auto-Activation) 🆕

Watches for reconnections and automatically activates devices with auto-activation enabled

1. Auto-Start: When you enable auto-activation for a device, the connection monitor starts
2. Continuous Watching: Checks for newly connected devices every 1 second (fast!)
3. Smart Activation: When a device reconnects:
   • Checks if device has auto_activate enabled in backend
   • Verifies device is currently inactive
   • Automatically creates tunnel and activates device
4. Zero Manual Intervention: Once enabled, devices reconnect automatically when plugged back in

What This Means for You

✅ No Manual Monitoring - Everything happens automatically ✅ Lightning Fast Detection - Disconnects/reconnects detected within 1 second! ✅ Clean State - No stale tunnels or active states ✅ Zero Maintenance - Daemons manage themselves ✅ Opt-in Auto-Reconnect - Enable per device as needed

Example Flow (With Auto-Activation)

# 1. Add a device with auto-activation enabled
$ bridgelink devices add emulator-5554 --auto-activate
🔍 Starting background health monitor...
   ✅ Health monitor started
🔌 Starting auto-activation connection monitor...
   ✅ Connection monitor started
💡 Health monitoring is active - disconnected devices will be auto-deactivated
🔄 Auto-activation ENABLED - device will auto-reconnect when plugged back in

# 2. Device gets physically disconnected
#    (Health monitor 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. Device gets reconnected (USB plugged back in)
#    (Connection monitor automatically detects and activates)
#    Logs to ~/.bridgelink/connection_monitor.log:
#    🔌 Detected 1 newly connected device(s)
#    🔄 Auto-activating device: emulator-5554
#       Setting up ADB TCP mode...
#       Creating bore tunnel...
#       Tunnel URL: bridgelink.nativebridge.io:15751
#    ✅ Device emulator-5554 auto-activated successfully
#
#    ← No manual intervention needed!
