Pulls fit files from your cycplus M1 bicycle computer
This is largely based off of Kaiserdragon2 CycSync android app (https://github.com/Kaiserdragon2/CycSync), only re-purposed to download the FIT files directly to your computer. From here you can do what you wish with them, including upload them to strava. I personally view them locally with Fit File Viewer: https://github.com/Nick2bad4u/FitFileViewer
Usage: You'll need a working pyhton install and the python package called bleak. Assuming you have python working, a pip install bleak should get you all the requirements. From there just run the python file. If it doesn't find your bike computer you might have to find the name of it and change line 7. Id you don't have a cycplus M1, you'll definitely have to change line 7. This is bluetooth LE, file transfers are not very fast.
