How to get the UHK80 to broadcast on BT

I connected my UHK80 via BT then had my Mac disconnect from it as I wanted to go back to using the cable connection.

Now I cannot see the UHK80 to reconnect via BT. Forgetting the device does not make it show up again either. Is there something that needs to be done to get the UHK80 to make itself visible? To repair?

After flashing the firmware again I can see it. However, now if I disconnect I cannot reconnect. Just a spinner and then nothing.
Me thinks the BT connectivity is a tad flaky.
