Android蓝牙GATT timetout with Nordic Thingy:52

Question

我有一个安卓应用程序，通过库(Thingylib)连接到thingy52后：

BluetoothDevice dev = scanResultList.get(nordicDeviceEntityList.get(pos).getAddress());
thingySdkManager.connectToThingy(getContext(), device, BaseTService.class);

我想要读取北欧thingy:52数据和RSSI值，因此在另一个活动中，当我想要收集数据时，我附加了一个新的蓝牙GATT：

private void startDataCollection() {
        for (BluetoothDevice dev : thingySdkManager.getConnectedDevices()){
            thingySdkManager.setConstantLedMode(dev, 1, 100, 1);
            ThingyListenerHelper.registerThingyListener(getApplicationContext(), mThingyListener, dev);
            //e vents
            thingySdkManager.enableMotionNotifications(dev, true);

            gatt = dev.connectGatt(getApplicationContext(), true, gattCallback);
        }
}

之后，在thingylib的Accellerometer事件回调中，我获取数据并调用GATT来检索RSSI值：

@Override
        public void onAccelerometerValueChangedEvent(BluetoothDevice bluetoothDevice, float x, float y, float z) {
            gatt.readRemoteRssi();
        }

我发现的问题是，几秒钟后(不确定，有时是5/10s)，设备断开连接，GATT上出现错误8(超时错误)。如果我在收集数据之前删除GATT链接，设备不会断开连接，并且工作正常。我想知道是否有一种方法可以防止连接的GATT超时或我做错了什么。

问题似乎出在设备的固件方面，就像github问题所指出的那样：https://github.com/NordicSemiconductor/Android-Nordic-Thingy/issues/22
