Are you letting the driver auto-detect, or have you selected a specific driver? 
If you've selected a specific driver, which one?

The BP12 is interesting in that it uses protocols implemented by other drivers. 
Older BP12s need the Voyager driver whereas newer ones default to needing the 
Alva driver (although there's a way to switch them back to the Voyager 
protocol).

BRLTTY uses the device's Bluetooth device name to direct it to the correct 
driver. I don't yet know what the Bluetooth name of a Braille Pen looks like, 
so it isn't in brltty's Bluetooth device name table. Can you send me exactly 
what it's Bluetooth device name is. Note that things like case and where spaces 
are are important.

I can't see enough in your logs to know exactly what brltty was doing at the 
time. Could you please go into brltty's Advanced Settings screen and set the 
Log Level to Debug, as well as enable the log category named Bluetooth I/O?

One thing your log does contain is a lot more Android debug information for 
Bluetooth. I don't (yet) know how to get it to do that. Would you mind giving 
me a lesson (or more) on how to get Android to log this additional information?
