Protocol and support for other devices

[mphx12]

Gadgetbridge supports a number of devices and implements two protocols, a V1 for older devices (e.g. the WH-1000XM3) and a V2 (e.g. WF-1000XM4). Some pointers:

  I'm considering spending some time on this to add support for V1 devices. Do you have any thoughts or on integrating this?

Hello, I no longer own my WF-1000XM4 so i will probably no longer work on this. I might help out on some point if i feel like it or if a buy a new sony headset in the future.

If you want to take over the project please feel free to do so.
