Wireshark logs along with a description are much needed!

I should get the required logs shortly. Pulling them from android is a pain but from a look in wireshark it should be good to go.

Yeah, after taking a peek in the app it is of course heavily obfuscated mainly in the part that are sensible to create a cross compatible app (communication protocols). I was searching for a generic library to control various vendors of audio gear with a Decky plugin app for Linux, and this looks a great project to start with for SoundCore hardware (besides the issue with the RFCOMM library on other platform, but I can take a look at that and see if I can replace it with something else).

Anyway, here are the logs while interacting with the app.

Removed since OpenSCQ30 now has implemented support for it, therefore I don't really need this anymore and I would prefer to not leave mac addresses around the web if not needed.
