Подключение H C -05 к Android для получения данных от Arduino

Question

05 и arduino Uno для отправки строки в мое приложение android. Но я не могу получить данные. Я не уверен, что делаю неправильно. Я следил за учебником в Интернете. Единственное, что я отредактировал, - это функция отправки данных, поскольку я просто хочу слушать данные, поступающие в приложение android. Приложение работает без ошибок, но ничего не делает.

 TextView myLabel;
TextView temperatureData;
EditText myTextbox;
BluetoothAdapter mBluetoothAdapter;
BluetoothSocket mmSocket;
BluetoothDevice mmDevice;
OutputStream mmOutputStream;
InputStream mmInputStream;
Thread workerThread;
byte[] readBuffer;
int readBufferPosition;
int counter;
volatile boolean stopWorker;
String selectedBt;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bluetooth_test);

    selectedBt = getIntent().getStringExtra("btName");

    Button openButton = (Button)findViewById(R.id.open);
    Button closeButton = (Button)findViewById(R.id.close);
    myLabel = (TextView)findViewById(R.id.label);
    temperatureData = (TextView)findViewById(R.id.tempSensorDataLabel);


    try
    {
        findBT();
        openBT();
    }
    catch (IOException ex) { }

    //Open Button
    openButton.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View v)
        {
            try
            {
                findBT();
                openBT();
            }
            catch (IOException ex) { }
        }
    });

    //Send Button


    //Close button
    closeButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            try {
                closeBT();
            } catch (IOException ex) {
            }
        }
    });
}

void findBT()
{
    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    if(mBluetoothAdapter == null)
    {
        myLabel.setText("No bluetooth adapter available");
    }

    if(!mBluetoothAdapter.isEnabled())
    {
        Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
        startActivityForResult(enableBluetooth, 0);
    }

    Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
    mmDevice = mBluetoothAdapter.getRemoteDevice("E0:F8:47:43:68:E2");
    if (pairedDevices.contains(mmDevice))
    {

        Log.d("ArduinoBT","Bluetooth Device Found, address: " + mmDevice.getAddress() );
        Log.d("ArduinoBT", "BT is paired");
    }
    myLabel.setText("Bluetooth Device Found");
}
