[SOLVED] Bluetooth (ath10k) on Dell XPS 9560 not working

Post by JohanHarmsen » Thu Nov 23, 2017 4:37 pm

Hello

I installed Mint 18.2 on a new Dell XPS 9560 laptop in a dual boot configuration along side Window 10 (UEFI), works like a champ, but I have one small problem.
I cannot get my (Logitec M535) bluetooth mouse to work. It does work with Windows 10.
I've read a lot of posts, but none of the suggested solutions appeared to help.
Blueman and Blueberry cannot find the device, when I look with dmesg | egrep 'blue|firm'

Code: Select all

[    2.461149] [drm] GuC firmware load skipped

The file firware-5,bin does indeed not exits in the /lib/firmware folder, firmware-4.bin and firmware-6.bin do exist.
Tried to copy the file hw2.1/firmware-5.bin to the hw3.0 directory but then the Wireless network stopped working.

Attempted to reinstall linux-firmware: sudo apt install --reinstall linux-firmware (no effect, no changes in the .../ath10/QCA6174/hw3.0 directory)
Attempted to boot the original Mint 18.2 kernel: 4.8.0-53, no effect (Currently I'm running 4.10.0-40)

Have not tried to download and install the driver from https;//github.com/kvalo/ath10k-firmware, because I only see firmware-4.bin there and that is the one I already have and that is not used by the system. I have no clue where the information to load firmware-5.bin is stored, tried to search the /etc/ directory but got no hits.

Some other information that may be helpfull

So are you rebooting from Windows into Linux or doing a complete shutdown, then startup and boot into Linux. I don't see any info about firmware loading for the bluetooth and it might be because the Windows firmware hasn't been purged by powering off the device

I tried both, shutdown/wait a few minutes, start Mint. also restart Mint->Mint and Windows->Mint but the result is always the same.

After Linux Mint boots up,

Code: Select all

sudo modprobe -r btusb && sleep 20 && sudo modprobe btusb
See if that gets bluetooth running

No change, bt Mouse still not showing in Bluetooth Manager (Blueberry)
Out of frustration shaked the mouse, and for a moment the name of the mouse flashed up in the bt manager. Too short to select it. This was repeatable,

This does not help me further. In anther post I found bluetoothctl, this reports:

[NEW] Device 34:88:5D:53:A7:44 Bluetooth Mouse M336/M337/M535
[CHG] Device 34:88:5D:53:A7:44 Connected: no
[DEL] Device 34:88:5D:53:A7:44 Bluetooth Mouse M336/M337/M535

These events occur with minimal time delay between them.
It almost looks as if the mouse is recognized, but for some reason not registered, and stopped before it can be paired.

Checked which bluetoothr elated processes are runnng:

This might be a bug in the 4.10 kernels. Use the Mint Update Manager through View/linux kernels to install the newest 4.4.0 kernel 101 I think
Reboot and use the grub menu to boot using the 4.4 kernel

Hi Jeremy
That did the trick, after installation of kernel 4.4.0-101 and a reboot, the mouse appeared in the bt manager and was successfully paired.
Thanks for all your help ! I'll periodically test with new kernels to see if the problem is solved

Best regards

Johan
