[Solved] Bluetooth speaker hell

Hi,

I am trying to get my bluetooth speakers work (Soundcore Motion+ A3116), but with no luck.
I have already tried lot of tutorials, tried to use pipewire, but when I can get that work audio quality is terrible and anyway after a reboot they are not working.

I don' t even know which information I can provide to have support, since I have installed and tried many things that I don' t know where to start!

Anyway, I guess that following information could help you:

* bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
     Active: active (running) since Tue 2021-06-29 21:27:47 CEST; 12min ago
       Docs: man:bluetoothd(8)
   Main PID: 494 (bluetoothd)
     Status: "Running"

     CGroup: /system.slice/bluetooth.service
             `-494 /usr/lib/bluetooth/bluetoothd

Notice that bluetooth service has different log everytime that I restart the system. Sometimes I am able to connect to my speaker, but they are not recognized as spekaer, sometime (as in this case) I cannot even connect...

I am using i3 with GDM (and I have already try what is written here.
Kernel version: 5.12.13
Pipewire: 0.3.31

Thank you

Re: [Solved] Bluetooth speaker hell

FYI I solved. I got to dowgrade bluez to version 5.58, remove folder /var/lib/bluetooth, restart and repair the speaker.
I followed this post
