RxAndroidBle: Failed to reconnect device after bluetooth disable

Summary

Failed to reconnect to a device after switch on the bluetooth. And on every device when bluetooth enable weird exception.

Library version

1.4.3

Preconditions

• Honor 8 or Gretel gt6000

Steps to reproduce actual result

1. Establish connection
2. Kill bluetooth
3. try to establish again connection

Minimum code snippet reproducing the issue

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)



        val rxBleClient = RxBleClient.create(this)

        val device = rxBleClient.getBleDevice("XX:XX:XX:XX:XX:XX")

        button.setOnClickListener {

            subscriptor = RxJavaInterop.toV2Observable(device?.establishConnection(false)?.doOnNext {
                Log.i(TAG, "connected RX")
            })?.subscribe({
                Log.w(TAG, "connected")
            }, {
                Log.e(TAG, "error",it)
            })

        }
    }

Logs from the application running with setting RxBleLog.setLogLevel(RxBleLog.VERBOSE)

Actual result

Impossible to reconnect to the device even when we close the application.

The weird things is when I try to click (first time) why the Bluetooth disable I get :

Not only on the Honor is that normal ?

Expected result

To be able to turn on bluetooth and connect to the device again. And an other exception like Bluetooth Adapter not available
