If needed i would upload btsnooping log.

Please get the BS444 closer to your BT receiver and try again. I mean very close for testing like less than 1 meter.
done. But with no changes. same error:

You're missing handles that's why I thought about distance but it might be a bug in an outdated dependency.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 peplin/pygatt#152, peplin/pygatt#161 and peplin/pygatt#166
works.
sudo apt-get install python-dev (for coverage.py)
sudo pip install "pygatt[GATTTOOL]==3.1.1"
thank you
Great! Will add a comment in the readme for the time being.
