RxAndroidBle BleAlreadyConnectedException

Question

I´m trying to establish a connection that will auto connect again if the connection was once lost. With the start of a commissioning when connection is established again.

So the first connection works perfect, and I can set up notifications from the rxBleConnection. But when I turn off my ble board I get the BleAlreadyConnectedException and I´m not able to connect unless I close the app again.

fun connect(address: String) {
    if (mRxBleClient == null || address == null) {
        Log.e(TAG, "mRxBleClient not initialized or unspecified address.")
    }

    mRxDevice = mRxBleClient?.getBleDevice(address)
    mRxDevice!!.observeConnectionStateChanges() // Observe changes to the ble connection
            .subscribe(
                    { connectionState ->
                        when (connectionState!!) {
                            RxBleConnection.RxBleConnectionState.CONNECTED -> {
                                Log.e(TAG, "Device connected")
                                broadcastUpdate(ACTION_GATT_CONNECTED)
                            }
                            RxBleConnection.RxBleConnectionState.CONNECTING -> {
                                Log.e(TAG, "Device connecting")
                                broadcastUpdate(ACTION_GATT_CONNECTING)
                            }
                            RxBleConnection.RxBleConnectionState.DISCONNECTING -> {
                                Log.e(TAG, "Device disconnecting")
                                broadcastUpdate(ACTION_GATT_DISCONNECTING)
                            }
                            RxBleConnection.RxBleConnectionState.DISCONNECTED -> {
                                Log.e(TAG, "Device disconnected")
                                broadcastUpdate(ACTION_GATT_DISCONNECTED)
                            }
                        }
                    },
                    { throwable ->
                        // Handle an error here.
                        Log.e(TAG, "Connection state throwable " + throwable)
                    }
            )

    mDeviceAddress = address

    createConnection()

}

fun createConnection() {
    connectionSubscription = mRxDevice!!
            .establishConnection(true)
            .observeOn(AndroidSchedulers.mainThread())
            .doOnUnsubscribe(this::clearSubscription)
            .subscribe(
                    {
                        rxBleConnection ->
                        Log.e(TAG, "Connected")
                        mRxBleConnection = rxBleConnection

                        isCommissioning = true

                        setUpNotification() // When connected try to set up the notifications
                    },
                    {
                        throwable ->
                        Log.e(TAG, "Something went wrong when connecting " + throwable)
                    }
            )
}

And the notifications

    fun setUpNotification() {
Log.e(TAG, "setUpNotification")

    mRxBleConnection!!.discoverServices().subscribe({ service ->
        service.getService(Data_Message_UUID).forEach({ layer ->
            for (character in layer.characteristics) {
                setCharacteristicNotification(character)
            }
        })
    })
}

So the first connection works just fine. But after a restart of my board the connectionObservable gives me the error BleAlreadyConnectedException status 8

I want the app to connect again and set up the notifications once again for the new connection.
