First of all, thanks a lot for sharing this library. Great work.
When trying the clock.py, I'm getting following error.
Any idea how to proceed?

Thanks in advance

I believe that the bluetooth connection is ok?

The above was a connection problem which I could solve on bluetooth level.
Getting other error now

I think best option is actually ditch pygatt dependency. Other options include:
https://github.com/getsenic/gatt-python
https://bitbucket.org/OscarAcena/pygattlib

adding pip install pygatt==3.1.1 to the readme will solve a lot of people's problems :)

@IlyaSukhanov thanks a lot for the library! my daughter was super impressed we can use python on the dash
and my dog was extremely upset at it haha

@jackdoe Glad you find it useful. Was the problem that the later version of pygatt >4 does not work?

ah sorry i should've been more specific, with pygatt > 3.2 i couldnt connect at all
after following peplin/pygatt#161 and downgrading to 3.1.1 everything was fine
