Hey,
I am the developer building OAM (openAthleteMetrics) which is a BYOB (bring you own band) app designed to use a driver system to work with any band someone can build a driver for based off a protocol.

Rather than integrate connection and sync systems into the app it uses a json file with embedded web assembly to give the app the details of how to connect and sync with the device then the app handles it and returned the raw packets to the driver to parse (the embedded web assembly) then if needed that is handed to another part of the driver to be processed into metrics ( yet to be implemented).

I believe that the Whoopsie protocol could be implemented into OAM without any huge effort and provide a hugely practical use to both the app and old hardware.

If you are interested in just checking out the project or helping in any way, check it out here:

Thanks for the work developing this protocol,
