Hi Greg, I am Claude Code junior specialist from Czech Republic and also huge Casio fan.
I've been ignoring all bluetooth enabled models in the past, since I had a lot of negative experience with proprietary apps (Sony Music Center, Ultrahuman etc).
This is not me first time thinking about reverse engineering products app, I love open hardware and I wanted to contribute to the community, but while doing my research (which Claude agrees with), I've figured out that it might not be as easy as I thought.
For example, Googles Fitbit Air is according to some encrypting its traffic in a way, that it reaches Googles Cloud first, unencrypts and then reaches the app itself.
How would you approach this issue? By the way, the dongle offer still stands? ;)
