Comment résoudre l'erreur onClientConnectionState () - status=22 clientIf=7 in BLE

j'ai une application Android qui utilise pour se connecter Bluetooth Basse Énergie (blable) avec mon téléphone. L'application a bien fonctionné dans le presque téléphone tels que Galaxy S5 (Android 5.0.1), Galaxy S6 (Android 6.0). Cependant, il a un problème critique dans Galaxy Note 3 (Android 5.0.1).

quand j'appelle le connect() fonction, et ensuite appeler le readCharacteristic(), elle renvoie l'erreur:

onClientConnectionState ()=22 clientIf=7

L'erreur se produit après j'appelle connect fonction environ 2 secondes. Je chercher une solution, comme la fabrication de retard avant d'appeler readCharacteristic(), mais il ne peut pas résoudre.

auriez-vous un moyen de résoudre mon problème?

Merci à tous.

voici mon code:

 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);
 }
