Simple example code, big problem. Any ideas?
Android.Bluetooth.BluetoothSocket _socket = null;
Java.Util.UUID uuid =
Java.Util.UUID.FromString("00001101-0000-1000-8000-00805F9B34FB");
foreach (Android.Bluetooth.BluetoothDevice dev in
bluetoothAdapter.BondedDevices)
{
if (dev.Name.ToLower() == "root") //Device exists
{
_socket = dev.CreateRfcommSocketToServiceRecord(uuid);
break;
}
}
try
{
_socket.Connect();
}
catch (Exception ex)
{
throw ex;
}
