Add ability to ready Sony/Samsung battery levels #4

Hello @Toxblh

I trying to get multiple battery reporting working for the extension. But before I work on the GUI, i was looking at how to get L/R/Case information.

Do to this purely in Gjs may be quite complex.

So I have trying this python script, just could not get is working with my jabra earbuds connected.

It only works when my earbud is disconnected.

I am guessing since pipewire is using this rfcomm port/channel hence the script cannot communicate.

I saw your script for sony and it seem to be based TheWeirdDev script.

Does it work when your sony earbuds are connected and streaming? Or do you have to disconnect sony earbuds, to get battery levels or change modes?

Let me know how did you workaround this problem.

After some time I found @steam3d expose his solution which provide strong backend for AirPods,Sony and etc headphones with enhanced ability

Yes. I did find it few days back. It was written in c language. But whenever I ran it, it would disconnect the airpods and connected it back again. But it did gave all the information. Lately changed to python. I didn't try that. But looks promising.

Also I was trying to achieve communication with either rfcomm or l2cap purely in gjs. It think there is no way. I could not find a way to connect to bluetooth socket purely in gjs.

Do you have any idea about connecting to bluetooth socket in gjs?

@maniacx It's an early version; we are discussing the API and structuring the backend. It will be used in MagicPodsDecky as an example of building a UI based on a Python backend.

It's because when the headphones are connected, the system connects to the Hands-Free RFCOMM service. Classic Bluetooth allows only one active connection to a profile, so you need to disconnect Hands-Free if you want to get battery information from it. The microphone of the headphones will no longer work until the system reconnects to Hands-Free.

We can write small dbus adapter and be possible have gjs. But will need a demon. Or integrate that to the bluez, and publish the data to dbus

vulpes2 commented 1 month ago

MagicPodsCore has been re-licensed to GPLv3 and it's currently being rewritten in Python. Once the project is in good shape, a daemon can be made that exposes a dbus interface to make it easy to access from GJS. BlueZ also provides the ability to register battery providers which might be worth looking into.

Sony and Samsung earbuds do not use the HFP RFCOMM channel for vendor app communication. Anything that requires HFP in-band communication will need to have the battery status support implemented in pipewire.
