Nuimo does not correctly reconnect following a loss of bluetooth connection

[pouldam]

If the Nuimo controller looses the bluetooth connection it tries to reconnect. It looks like it is succesful (checkmark icon on Nuimo controller), but the controller does not respond afterwards and the display remains black.

To Reproduce Steps to reproduce the behavior: 0. Make sure the Nuimo is connected to the Raspberry Pi and everything is working as it should

1. Move the Nuimo out of bluetooth range from the Raspberry Pi
2. The Nuimo flashes the bluetooth logo to signal that connection is lost
3. Move the Nuimo back into bluetooth range from the Raspberry Pi
4. After a short while the Nuimo flashes the checkmark signaling that the connection is restored
5. Using the Nuimo afterwards nothing happens and the Nuimo display remains black.
6. Restarting the nuimo-openhab service on the Raspberry Pi fixes the issue

Expected behavior After moving the Nuimo back into bluetooth range and seeing that is displays the checkmark, I would expect it to be working normally.
