Please get the BS444 closer to your BT receiver and try again. I mean very close for testing like less than 1 meter.

You're missing handles that's why I thought about distance but it might be a bug in an outdated dependency. The log should include information about that. Can you check your system and dependencies versions?

@mod25 What version of Pygatt do you use? I've seen people having trouble reading characteristics using Pygatt 3.2 (where 3.1.1 was working fine). See https://github.com/peplin/pygatt/issues/152, https://github.com/peplin/pygatt/issues/161 and https://github.com/peplin/pygatt/issues/166

mod25 commented 6 years ago

works. sudo apt-get install python-dev (for coverage.py) sudo pip install "pygatt[GATTTOOL]==3.1.1" thank you

keptenkurk commented 6 years ago

Great! Will add a comment in the readme for the time being.
