相关疑难解决方法(0)

我有一个Android应用程序,用于连接蓝牙低功耗(BLE)和我的手机.该应用程序在Galaxy S5(Android 5.0.1),Galaxy S6(Android 6.0)等近乎手机中运行良好.但是,它在Galaxy Note 3(Android 5.0.1)中存在一个关键问题.

当我调用该connect()函数,然后调用readCharacteristic()它时,它返回错误:

onClientConnectionState() - status = 22 clientIf = 7

我调用connect函数约2秒后发生错误.我查找了一些解决方案,比如在通话前做出延迟 readCharacteristic(),但是无法解决.

你能解决我的问题吗？

谢谢大家.

这是我的代码:

 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(); …

我有一个从IntentService调用的BluetoothLeService.BLEService工作正常,直到它连接.在与iBeacon建立连接后,它会调用;

public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
            String intentAction;
            if (newState == BluetoothProfile.STATE_CONNECTED) {
                intentAction = ACTION_GATT_CONNECTED;
                mConnectionState = STATE_CONNECTED;
                broadcastUpdate(intentAction);
                Log.i(TAG, "Connected to GATT server.");
                // Attempts to discover services after successful connection.
                Log.i(TAG, "Attempting to start service discovery:" +
                        mBluetoothGatt.discoverServices());
            } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
                intentAction = ACTION_GATT_DISCONNECTED;
                mConnectionState = STATE_DISCONNECTED;
                Log.i(TAG, "Disconnected from GATT server.");
                broadcastUpdate(intentAction);
            }
        }

到目前为止一切都还可以,但在此之后,尽管mBluetoothGatt.discoverServices()返回true,但从不调用onServicesDiscovered(BluetoothGatt gatt,int status).

--------------------- UPDATE ---------------------------- ------

在调试时它显示newState == BluetoothProfile.STATE_CONNECTED但它没有真正连接.对于属于未使用设备的假id,它显示相同的结果.

这是我的回调
