Bluetooth is provided by: Bus 001 Device 003: ID 0e8d:0616 MediaTek Inc. Wireless_Device I believe. This is a gmktec nucbox k8 plus by dmi information. With distribution's 7.0 kernel bluetooth shows up fine in Gnome and I can connect my headphones and get audio. Using "linux-git" package, which built 7.1-rc3 (+ some commits on top in torvalds tree). Booting to it, bluetooth can't be enabled in Gnome, everything stays grayed out and no devices are shown. (I tried 7.1-rc1 earlier, which also didn't work, but I didn't take any notes back then.) The difference in dmesg is that on 7.0: [ 6.152649] Bluetooth: hci0: Device setup in 173263 usecs [ 6.152661] Bluetooth: hci0: HCI Enhanced Setup Synchronous Connection command is advertised, but not supported. [ 6.216582] Bluetooth: hci0: AOSP extensions version v1.00 [ 6.216593] Bluetooth: hci0: AOSP quality report is supported 8<-- 8<-- And on 7.1-rc3: [ 6.270455] Bluetooth: hci0: Failed to send wmt func ctrl (-22) [ 6.270466] Bluetooth: hci0: HCI Enhanced Setup Synchronous Connection command is advertised, but not supported. 8<-- 8<-- There are some changes in btmtk.c between these versions, but can't see on glance anything wrong with them, only adding support for MT6639. I'm not on the list, please Cc: if I can provide more info. Cheers, Taneli
