android – BluetoothGattCallback为Beacon返回129 – > GATT_INTERNAL_ERROR,但为手机返回0

我打电话给我的蓝牙适配器mBluetoothAdapter.startDiscovery();然后返回一个BluetoothDevices列表.当我按下其中一个设备时,我这样做：

mBluetoothGatt = bluetoothDevice.connectGatt(MainActivity.this,false,mGattCallback);

我的回调是：

private final BluetoothGattCallback mGattCallback =
        new BluetoothGattCallback() {
            @Override
            public void onConnectionStateChange(BluetoothGatt gatt,int status,int newState) {
                if (newState == BluetoothProfile.STATE_CONNECTED) {
                    mConnectionState = STATE_CONNECTED;
                    Log.i(TAG,"Connected to GATT server.");
                    Log.i(TAG,"Attempting to start service discovery:" +
                            mBluetoothGatt.discoverServices());
                    List<BluetoothGattService> listBGS = mBluetoothGatt.getServices();
                    Log.i("","list size: " + listBGS.size());

                } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
                    mConnectionState = STATE_DISCONNECTED;
                    Log.i(TAG,"Disconnected from GATT server.");
                }
            }

            @Override
            // New services discovered
            public void onServicesDiscovered(BluetoothGatt gatt,int status) {
                if (status == BluetoothGatt.GATT_SUCCESS) {
                    Log.w(TAG,"onServicesDiscovered GATT_SUCCESS: " + status);
                    List<BluetoothGattService> listBGS = mBluetoothGatt.getServices();
                    Log.i("","list size: " + listBGS.size());
                } else {
                    Log.w(TAG,"onServicesDiscovered received: " + status);
                }
            }

            @Override
            // Result of a characteristic read operation
            public void onCharacteristicRead(BluetoothGatt gatt,BluetoothGattCharacteristic characteristic,"onCharacteristicRead GATT_SUCCESS: " + status + " / char: " + characteristic);
                }
            }
        };

现在,当我在手机上试用它时,我在onConnectionStateChange上获得了STATE_CONNECTED,然后我调用了discoverServices,然后我返回了一个GATT_SUCCESS onServicesDiscoveres.所以我可以从我的服务中取出uuids.
但是当我在信标上尝试它时,我回到STATE_CONNECTED,当我调用discoverServices时,我得到一个状态代码：129 – > GATT_INTERNAL_ERROR
为什么我的信标会发生这种情况？还有另外一种方法,我怎么能拿设备uuid？
对于beaconManager,我只需要UUID能够执行此操作：

try {
        beaconManager.startMonitoringBeaconsInRegion(new Region("myMonitoringUniqueId",null,null));
    } catch (RemoteException e) {    }

编辑

我知道灯塔应该问我配对的代码,但事实并非如此.为什么？
我尝试添加此代码：

final IntentFilter pairingRequestFilter = new IntentFilter(BluetoothDevice.ACTION_PAIRING_REQUEST);
    pairingRequestFilter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY - 1);
    registerReceiver(mPairingRequestRecevier,pairingRequestFilter);

但我仍然没有得到配对和输入密码的请求

这是我的pairingRequestReceiver：

private final BroadcastReceiver mPairingRequestRecevier = new BroadcastReceiver()
{
    @Override
    public void onReceive(Context context,Intent intent)
    {
        if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(intent.getAction()))
        {
            final BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
            int type = intent.getIntExtra(BluetoothDevice.EXTRA_PAIRING_VARIANT,BluetoothDevice.ERROR);

            if (type == BluetoothDevice.PAIRING_VARIANT_PIN)
            {
                device.setPin(intToByteArray(123456));
                abortBroadcast();
            }
            else
            {
                Log.e("","Unexpected pairing type: " + type);
            }
        }
    }
};

解决方法

经过几个小时的试验和错误,我确实设法找到一种方法让它像这样工作：
1.我开始发现相同,但当我选择蓝牙设备时,我要求与它绑定(配对)：

private void pairDevice(BluetoothDevice device) {
    try {
        Method method = device.getClass().getMethod("createBond",(Class[]) null);
        method.invoke(device,(Object[]) null);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

我有一个ACTION_BOND_STATE_CHANGED接收器：

private final BroadcastReceiver mPairReceiver = new BroadcastReceiver() {
    public void onReceive(Context context,Intent intent) {
        String action = intent.getAction();

        if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) {
            final int state        = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE,BluetoothDevice.ERROR);
            final int prevState    = intent.getIntExtra(BluetoothDevice.EXTRA_PREVIoUS_BOND_STATE,BluetoothDevice.ERROR);

            if (state == BluetoothDevice.BOND_BONDED && prevState == BluetoothDevice.BOND_BONDING) {
                Log.i("","Paired");
                mBluetoothGatt = btDevice.connectGatt(MainActivity.this,mGattCallback);
            } else if (state == BluetoothDevice.BOND_NONE && prevState == BluetoothDevice.BOND_BONDED){
                Log.i("","Unpaired");
            }

        }
    }
};

我注册的是这样的：

IntentFilter intent = new IntentFilter(BluetoothDevice.ACTION_BOND_STATE_CHANGED);
    registerReceiver(mPairReceiver,intent);

只有在此之后,我才尝试连接我的BluetoothGattCallback.因此,我可以发现服务,等等
