From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx> iThis set add initial support for BAP (Basic Audio Profile) which is an essential part of LE Audio responsible for stream control. The plugin is considered experimental and depends on ISO socket in order to work so the following setting needs to be changed in order to enable it: # Enables D-Bus experimental interfaces # Possible values: true or false +Experimental = true # Enables kernel experimental features, alternatively a list of UUIDs # can be given. @@ -126,7 +126,7 @@ # a6695ace-ee7f-4fb9-881a-5fac66c629af (BlueZ Experimental Offload Codecs) # 6fbaf188-05e0-496a-9885-d6ddfdb4e03e (BlueZ Experimental ISO socket) # Defaults to false. +KernelExperimental = 6fbaf188-05e0-496a-9885-d6ddfdb4e03e While proper support to the likes of PulseAudio and Pipewire are still in progress it is possible to test using bluetoothctl with the following commands: [Server/Peripheral] [bluetooth]# power on [bluetooth]# advertise on [bluetooth]# endpoint.register 00002bc9-0000-1000-8000-00805f9b34fb 0x06 [/local/endpoint/ep0] Auto Accept (yes/no): y [/local/endpoint/ep0] CIG (auto/value): a [/local/endpoint/ep0] CIS (auto/value): a Capabilities: 03 01 ff 00 02 02 03 02 03 03 05 04 1e 00 f0 00 ................
