Method FromBluetooth

FromBluetooth(BluetoothDevice)

Creates a NMEA LocationDataSource based on a bluetooth device port.

Declaration

[RequiresPermission("android.permission.BLUETOOTH")]
public static NmeaLocationDataSource FromBluetooth(BluetoothDevice device)

Parameters

Type	Name	Description
Android.Bluetooth.BluetoothDevice	device	The Bluetooth Serial service.

Returns

Type	Description
NmeaLocationDataSource	A NMEA Location Datasource that reads from the specified bluetooth port

Remarks

The created datasource will automatically handle creating and opening the specified serial port when the datasource is started. Once the datasource has been started, the NmeaDataStream will be available.

To use this device, ensure you have the necessary permissions set in the AndroidManifest.xml file:

  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <uses-permission android:name="android.permission.BLUETOOTH" />

To get a list of serial devices, use the serial-over-bluetooth UUID 00001101-0000-1000-8000-00805F9B34FB to look for usable devices:

public static IEnumerable<BluetoothDevice> GetBluetoothSerialDevices()
{
    Java.Util.UUID serial_uuid = Java.Util.UUID.FromString("00001101-0000-1000-8000-00805F9B34FB"); // Guid for bluetooth serial devices
        var adapter = BluetoothAdapter.DefaultAdapter;
    if (adapter != null && adapter.IsEnabled)
    {
        foreach (var b in adapter.BondedDevices.Where(d => d.GetUuids().Any(t => serial_uuid.CompareTo(t.Uuid) == 0)))
            yield return b;
    }
}
