Add support for P40i
Arch Llinux, Gnom, Wayland.
I tried to connect my P40i earbuds, but I got an error. There is the log from the terminal.

Let me know if you need more info.
Hey I am interested in working on this but could do with help finding the right bluetooth packets. I've got Wireshark working as per these instructions but cannot identify any relevant settings information.
Does this filter help? btrfcomm contains 08:ee:00:00:00 || btrfcomm contains 09:ff:00:00:01
Everything will be prefixed with one of those two sets of 5 bytes. Numbers are from here, with the former being from app to earbuds (outbound) and the latter being from earbuds to app (inbound).
Here's an example from some Q20i logs someone sent me a while back.
Ah I think I've got somewhere, it doesn't automatically send the settings on connection but does when I use .\openscq30_cli-windows-x86_64.exe get transparency-mode (or several of the 'get' commands) in the command line. Your filter works in that case.
Here is an example packet for the p40i:

Now hopefully I can begin the slow process of deciphering which byte is which!
I forgot that I actually started deciphering it already a few months ago. This is what I had done, so you can use it for reference if you want: https://github.com/Oppzippy/OpenSCQ30/blob/master/tools/soundcore-device-faker/devices/a3955.toml
At a glance, the main thing of note is that it uses an unusual button configuration format that is, out of the currently implemented devices, only shared with the a3959: https://github.com/Oppzippy/OpenSCQ30/blob/4b5f9c2811d967da1492f5ccdd4bfde5e0593c67/lib/src/devices/soundcore/a3959.rs#L58-L114
