Also working on a yowu headset app!

[FredYeye]

Hi there! Wish I had found this earlier, but alas! I also wrote a program for controlling yowu headsets (specifically the selkirk-4 model, but i'm guessing it could easily be changed to control other models) from a PC! Haha.

I only had the "FC040106" commands figured out more or less, didn't know what command 08 was (init? doesn't seem to be needed?), I see you also found something else (audio EQ?), neat!

I've decompiled the yowu app and found a long list of commands (as strings) and related functions, but it takes a lot of time to look through it all.

The actual reason I wrote this program was because the audio latency sometimes becomes really, really high. I speculated it was because i had the headset connected both to my PC and phone, but it seems to be something else. I've resorted to using the cable for now... I know the headset itself is fine because the latency is fine when it's connected to the phone. Gotta keep looking for a solution there. 🤷

Anyway, I thought I'd reach out and see if you're interested in any of this, figuring out the commands or whatnot!

@FredYeye hey hey! Yeah my approach also involved a decompile of the android app.

Audio latency I suspect is due to somewhat false advertising about the AptX capabilities of the device - "low latency AptX" is how Yowu phrases it, but it's standard AptX, not AptX-LL. Also if your PC or phone isn't using AptX the traditional Bluetooth audio protocols are pretty laggy.

@FredYeye I don't have the time to work on this project at the moment, but if you have new discoveries to contribute by all means I encourage you to update the README in this repo! Happy to accept pull requests.

Ah, alright! Yeah I haven't looked at it much recently either... I made this for my SO but she hasn't been using her headset so 🤷 haha.

Regarding the audio latency, it's still a mystery to me. It used to be fine but now it's really, really high... as if some setting has changed. I'll have to look into AptX, but i don't even know how you'd go about changing that, if that is indeed the setting that has changed.
