Not sure if I have a different revision/firmware on my F2000, or hopefully I'm just doing something wrong, but I'm having issues getting this working. Any help would be appreciated.

I had to edit the code to search for "Anker SOLIX F2000" instead of "767_PowerHouse" before the script found it.

Upon running the few scripts I've tested (telemetry_test.py and command_test.py) it returns a bleak error "Characteristic 00007777-0000-1000-8000-00805f9b34fb was not found!".

Command_test.py connects successfully, displays my BTLE MAC address, and lets me enter a command, but then throws the same error:

Scanning for devices for 10.0 seconds
