I run libreelec on a Zotac Nano CI320, currently running 9.2.0 - with a Bluetooth dongle using Broadcom bluetooth chip BCM20702A0
When I upgraded to 9.2., my bluetooth speakers stopped working.
Code
[bluetooth]# devices
Device A0:E9:DB:90:12:D2
[bluetooth]# connect A0:E9:DB:90:12:D2
Attempting to connect to A0:E9:DB:90:12:D2

[CHG] Device A0:E9:DB:90:12:D2 Connected: yes
[CHG] Device A0:E9:DB:90:12:D2 Connected: noThis is a know regression in Linux kernel 5.1.15 - 203997 – [REGRESSION] Unable to connect BT audio device on 5.1.15 where bluetooth devices will not connect, esp. with a Broadcom BCM20702A0 chip on the server.
The regression seemed to disappear already in version 5.1.16 .
Will there be a libreelec patch release that uses a later kernel?
Also, 9.2.0 is missing a patch file for the Broadcom
