Bug Description

Tested on Dell XPS 9370, Ubuntu 18.04 Dell OEM iso

Bluetooth mouse tested with HP X40000b BT Last mouse stops responding after long extended deep sleep (24-48 hours).

Bluetooth settings window which initially reported Bluetooth as connected now shows disconnected. Pushing the button within the settings window to reconnect takes me back to off. Switching back to on and off keeps bringing me back to off unless I reboot the device and or turn off the mouse via the underneath portion of the BT device.

Demsg logs shows an extremely large number of "Bluetooth: hci:0 last event is not cmd complete (0x0f)"

More detailed information on this issue is below:
The customer has Ubuntu OEM through Dell. The laptop goes into deep sleep over night and they can no longer use their BT devices. You click on bt via GUI and try to toggle on and it looks like it is doing something and goes right back to off.

I am told by internal engineering the Qualcom fix below is being tested for this issue:


Can you get me more information about this and when it is being released?

Dell OEM image with updated kernel has the qca\qca6174 fix. I reloaded the dell image and have not been able to reproduce this issue with LE BT mouses. I will let it run and confirm. So it looks like the issue is just with the generic image not dell image. non-oem.

Thanks. If comments #4-#5 are correct then this bug should be assigned to package 'linux-firmware' instead of 'bluez'.

Looks like the same chip as bug 1520343. Maybe merge with that bug, or update it.
