的Android BLE的通知三星S4

我使用谷歌BLE SDK，我對三星S4（4.3），索尼Z1緊湊型（4.3），HTC新（4.4）但只有三星檢驗關於BLE應用工作S4剛異常的Android BLE的通知三星S4

問題調用時setCharacteristicNotification（布爾啓用）如果我得到onDescriptorWrite回撥，然後開始得到通知約5〜6秒我會得到GATT服務斷開回調的數據，以及我的日誌只輸出9倍，正常日誌會輸出42次，

對不起，我的英文很差，我只是用我的代碼和日誌幫助的人能理解我的問題

setCharacteristicNotification

public boolean setCharacteristicNotification(boolean enabled){ 


     if (mBluetoothAdapter == null || mBluetoothGatt == null) { 
      Log.w(TAG, "BluetoothAdapter not initialized"); 
       return false;  
     } 

     BluetoothGattService Service = 
       mBluetoothGatt.getService 
       (UUID.fromString(GattAttributes.SONOSTAR_SENSOR_UUID)); 
     if (Service == null) { 
      Log.e(TAG, "service not found!"); 
      return false; 
     } 

     BluetoothGattCharacteristic characteristic = 
       Service.getCharacteristic 
       (UUID.fromString(GattAttributes.SONOSTAR_NOTIFY_R)); 

     final int charaProp = characteristic.getProperties(); 

     if ((charaProp | BluetoothGattCharacteristic.PROPERTY_NOTIFY) > 0) { 
      mBluetoothGatt.setCharacteristicNotification(characteristic, enabled); 

      BluetoothGattDescriptor descriptor = characteristic.getDescriptor(
        UUID.fromString(GattAttributes.CLIENT_CHARACTERISTIC_CONFIG)); 
      descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE); 

      mBluetoothGatt.writeDescriptor(descriptor); 

      return true; 
     } 

    return false; 

}

onCharacteristicChanged

@Override 
    public void onCharacteristicChanged(BluetoothGatt gatt, 
      BluetoothGattCharacteristic characteristic) 
    { 

     Log.i(TAG, "on notify" +""); 
      NOTIFY_DATA_ARRAY.add(characteristic.getValue()); 
      Log.i(TAG, NOTIFY_DATA_ARRAY.size() + " "+characteristic.getValue()); 
    }

你有沒有解決過這個問題？我們可以在多個設備上重現它。 –

謝謝你的回覆，即時解決這個問題。問題發生在我的設備上固件設置變量是錯誤的 – BearrrXD

您在固件中更改了哪些設置以使其工作？ –

從你的日誌定義服務器斷開呼叫。所以可能會有一段時間無法連接服務器（有時在ble服務器中定義）。因此，如果三星設備需要時間閱讀通知數據設備斷開它自己。

是的，如果我使用寫/讀/通知，然後s4將在30秒後斷開，但是當我呼叫setCharacteristicNotification，數據傳輸沒有完成，那是我的問題。這很奇怪 – BearrrXD

啓用通知後，只需顯式讀取一次，如下面的代碼爲三星設備所示。

變通

  try { 
      Thread.sleep(2000); 
     } catch (InterruptedException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     mBluetoothGatt.readCharacteristic(characteristic);

通知將啓動。當通信正在進行時，Tt工作但不工作（客戶端到服務器和服務器到客戶端持續在同一個特徵上）。
