@aromo Similar issue, couldn't connect UE Boom speaker was just getting
'Unable to register GATT service with handle 0x0001'. Found it strange
that even when the speaker was powered down bluetoothd kept trying to
connect (and disconnect seconds later)
What I found was, UE Boom speakers can be powered on remotely using the
mobile application - which is done through Bluetooth LE. This is why the
speaker was connected even when powered-down because of it was connected
via LE. I could be wrong but I believe the GATT service manages the
messages from LE devices - So I tried disabling Bluetooth Low Energy on
the laptop bluetooth adaptor through this command:
sudo btmgmt le off
Unpaired the speaker, restarted the laptop and afterwards I had no more
"Unable to Register GATT" or "Device is already marked connected
messages" and I was able to connect the speaker through Audio Sink.
Haven't had any issues with it since (except for having to run a2dp.py -
but that is a separate issue)
Perhaps you could try disabling le and see if it works for you too?
