  4. Select your device from the list.
  5. Accept the Bluetooth pairing prompt if shown.

💡 Tip: If your device doesn’t appear, check that Bluetooth and Location permissions are granted, and that the radio is not already connected to another device.

Troubleshooting Bluetooth

  • Device not found: Toggle Bluetooth off/on, ensure location is enabled.
  • Connection drops: Move closer to the radio; check for interference.
  • Pairing rejected: Forget the device in Android Bluetooth settings and retry.

USB Serial

USB connections provide a wired alternative, useful for desktop or when Bluetooth is unavailable.

Setup

  1. Connect your radio via USB cable to your device.
  2. The app will prompt for USB permission — tap Allow.
  3. The connection is established automatically.

⚠️ Note: USB connections require OTG support on Android devices.

TCP/IP (WiFi)

Some Meshtastic radios support WiFi connectivity, allowing TCP-based connections.

Nastavení

  1. Connect your radio to a WiFi network via the radio’s web interface or settings.
  2. In the app, go to Connect → TCP.
  3. Enter the radio’s IP address and port (default: 4403).
  4. Tap Connect.

WiFi scanning for devices

When a device is found, it appears in the connection list:

A successful connection is confirmed with a status indicator:

When to Use TCP

  • Radio is on the same local network
  • Testing with a simulated radio
  • Environments where Bluetooth has interference issues

Reconnection Behavior

The app reconnects to the last selected device on startup. You can switch transports from the Connect screen at any time.

To disconnect, tap the disconnect button on the Connect screen:

Disconnect from radio

On Desktop (Linux/macOS/Windows), the app supports:

  • Bluetooth (BLE) — via the Kable library; works on macOS, Linux, and Windows
  • USB Serial — primary wired connection method
  • TCP/IP — for network-connected radios
