Estoy creando una aplicación con Android Studio que puede leer el valor de un dispositivo BLE. Este dispositivo, tiene 4 servicios. Los cuartos servicios tienen 3 características. Quiero leer todas las características de este cuarto servicio.

Este dispositivo puede enviar más información, por lo que quiero que la aplicación pueda almacenar toda la información que llega del dispositivo BLE.

Entonces este es mi código:

@TargetApi(21)
public class BLEActivity extends BaseActivity {

    private BluetoothAdapter mBluetoothAdapter;
    private int REQUEST_ENABLE_BT = 1;
    private Handler mHandler;
    private static final long SCAN_PERIOD = 10000;
    private BluetoothLeScanner mLEScanner;
    private ScanSettings settings;
    private List<ScanFilter> filters;
    private BluetoothGatt mGatt;
    String mCurrentService;
    TextView tvBLE;
    ImageButton ibDownload;
    BluetoothDevice currDevice;
    private int id = 1000;
    public SensorDataAdapter adapter;
    final BLEActivity classe = this;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_ble);
        mHandler = new Handler();

        //mSensors = db.getAllSensorTypes();
        //BLUETOOTH LOW ENERGY NON SUPPORTATO
        if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) {
            Toast.makeText(this, "BLE Not Supported",
                    Toast.LENGTH_SHORT).show();
            finish();
        }
        final BluetoothManager bluetoothManager =
                (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
        mBluetoothAdapter = bluetoothManager.getAdapter();
        //VERIFICO SE IL BLUETOOTH DEL DISPOSITIVO E' ABILITATO
        //OPPURE NO. SE NON è ABILITATO DEVO CHIEDERE ALL'UTENTE DI ATTIVARLO
        // Ensures Bluetooth is available on the device and it is enabled. If not,
        if (mBluetoothAdapter == null || !mBluetoothAdapter.isEnabled()) {
            Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
        }

        ibDownload.setOnClickListener(new View.OnClickListener() {

                    scanLeDevice(false);// will stop after first device detection
                }

    }

                    db.insertSensorData(mSenData);


        }




    };
}

con este código, puedo leer una de las primeras características de mi servicio y solo un valor de la primera característica.

Quiero leer todos los valores de todas las características automáticamente de mi dispositivo BLE. ¿Cómo puedo cambiar mi código para hacer esto?
