I've actually done extensive work with reverse engineering garmin's bluetooth protocol for setting the time on my vivofit 3 watch without making an account! It's mostly shambled together stuff but I have a wireshark plugin that works pretty good for the few pieces it supports https://github.com/mjsir911/GarminBLE https://github.com/mjsir911/GarminBLE I started this project with no bluetooth experience either, it's definitely been a lot of learning. Let me know if you are interested in continuing / working on this, might give me a nudge to get back on it.
