I am having problem connecting via Bluetooth LE MID to my VOX Adio Air GT guitar amplifier. I was not able to debug the connection problem yet, but there was a bigger problem on hand: due to constant connecting/disconnecting ALSA seq resources were leaking until bluetoothd hung and ALSA backend crashed. I have described a bit more in the github issue: https://github.com/bluez/bluez/issues/225 I was able to fix the leak with the following patch. I am not sure if that is the right way to do this, though. As the relation between midi_disconnect() and midi_device_remove() functions is not clear to me, I have just copied some of the cleanup code from one to the other.
