pôvodné:
try {
    btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) {
    Log.e(TAG, "connect: Socket creation failed.", e);
    throw e;
}

reflexia:
Method m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
btSocket = (BluetoothSocket) m.invoke(device, 6);
