Python sample script to read sensor values
This script requires Python 3 and the bleak library (https://github.com/hbldh/bleak) and runs on PC or a Raspberry Pi. It listens to all available sensors and creates/appends a csv file for each sensor found. This is meant to be a sample program, it is not guaranteed to run properly and can be copied or changed for any purpose.
