Cómo resolver el error onClientConnectionState()-status=22 clientIf=7 en BLE (0)

Tengo una aplicación de Android que usa para conectar Bluetooth Low Energy (BLE) con mi teléfono. La aplicación funcionó bien en el teléfono casi como Galaxy S5 (Android 5.0.1), Galaxy S6 (Android 6.0). Sin embargo, tiene un problema crítico en Galaxy Note 3 (Android 5.0.1).

Cuando llamo a la función connect() , y luego llamo a readCharacteristic() , devuelve el error:

onClientConnectionState () - status = 22 clientIf = 7

El error ocurre después de que llamo a la función de connect aproximadamente 2 segundos. Busco alguna solución, como hacer un retraso antes de llamar a readCharacteristic() , pero no puede resolver.

¿Podrías tener alguna forma de resolver mi problema?

Gracias a todos.

Este es mi código:

private final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() { @Override public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) { if (newState == BluetoothProfile.STATE_CONNECTED) { mBluetoothGatt.discoverServices(); } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {} } @Override public void onServicesDiscovered(BluetoothGatt gatt, int status) { if (status == BluetoothGatt.GATT_SUCCESS) { try { Thread.sleep(500); readCharacteristic(); } catch (InterruptedException e) { e.printStackTrace(); } } else { Log.w(TAG, "onServicesDiscovered received: " + status); } } @Override public void onCharacteristicRead(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status) { } @Override public void onCharacteristicChanged(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic) { } }; public void readCharacteristic() { /*check if the service is available on the device*/ BluetoothGattService mCustomService = mBluetoothGatt.getService(UUID.fromString("00001c00-d102-11e1-9b23-00025b00123")); /*get the read characteristic from the service*/ BluetoothGattCharacteristic mReadCharacteristic = mCustomService.getCharacteristic(UUID.fromString("00001233-d102-11e1-9b23-00025b00a5a5")); mBluetoothGatt.setCharacteristicNotification(mReadCharacteristic, true); BluetoothGattDescriptor descriptor = mReadCharacteristic.getDescriptor( UUID.fromString(SampleGattAttributes.CLIENT_CHARACTERISTIC_CONFIG)); descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE); mBluetoothGatt.writeDescriptor(descriptor); }

Este es mi archivo de función de servicio completo para conectar BLE

public class ConnectionService extends Service{ private BluetoothLeService mBluetoothLeService; public String mDeviceAddress="0A:1B:6C:22:11:3D"; private ServiceMonitor serviceMonitor = ServiceMonitor.getInstance(); private final ServiceConnection mServiceConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName componentName, IBinder service) { mBluetoothLeService = ((BluetoothLeService.LocalBinder) service).getService(); if (!mBluetoothLeService.initialize()) { Log.e(TAG, "Unable to initialize Bluetooth"); } mBluetoothLeService.connect(mDeviceAddress); } @Override public void onServiceDisconnected(ComponentName componentName) { mBluetoothLeService = null; } }; @Override public void onCreate() { super.onCreate(); } @Override public IBinder onBind(Intent intent) { return null; } @Override public void onDestroy() { if(mGattUpdateReceiver!=null) { unregisterReceiver(mGattUpdateReceiver); } if(mServiceConnection!=null) { unbindService(mServiceConnection); } } @Override public int onStartCommand(Intent intent, int flags, int startId) { //If some device is connecting to phone, let disconnect if(mConnected==true) { mBluetoothLeService.disconnect(); } //If bluetooth is enable if (BleUtils.getBluetoothAdapter(getApplicationContext()).enable()) { Intent gattServiceIntent = new Intent(this, BluetoothLeService.class); bindService(gattServiceIntent, mServiceConnection, BIND_AUTO_CREATE); registerReceiver(mGattUpdateReceiver, makeGattUpdateIntentFilter()); //Try to reconnect if the connect is not successful if (mBluetoothLeService != null) { new CountDownTimer(3000,1000) { public void onTick(long millisUntilFinished) {} public void onFinish() { final boolean result = mBluetoothLeService.connect(mDeviceAddress); Log.d(TAG, "Connect request result=" + result); } }.start(); } } return START_STICKY; }
