Dell XPS 13 (9370) Bluetooth issues
I have the following problem with my Bluetooth module on my new Dell XPS 13 (9370) with Ubuntu preinstalled.
The bluetooth module gets disabled for some reason. The bluetooth devices (keyboard and mouse) just stop working in the middle of the work, the Bluetooth indicator goes away and the module is also gone in the rfkill list.
To get it back working I need to reboot the machine, start the BIOS, disable the Bluetooth module and re-enable it. After that, the bluetooth module is available again. That's pretty annoying.
My syslog when this happens:

Apr 11 12:25:48 visyu-albatross org.gnome.Terminal[2417]: ** (gnome-terminal-server:12197): WARNING **: Unable to set locale modifiers with XSetLocaleModifiers()
I already tried different things:
- Disabling TLP and disabling TLP for Bluetooth in
/etc/default/tlp - Updating the BIOS to version 1.2.1
- Setting this line to modprobe for ath10k:
echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf - Updating the
linux-firmwarepackage, like mentioned here: https://www.killernetworking.com/driver-downloads/kb/faq/1-killer-1535-1525-1435-in-ubuntu-debian
Nothing of this helped until now.
As far as I can see, it's the following hardware: QCA 6174 Killer Qualcomm / QCA 1535 Killer Qualcomm
Mostly I have these two bluetooth devices paired and connected:
- Logitech K810 keyboard
- Logitech MX Anywhere2 mouse
Solution 1:
I had the same problem, and I think it improved by updating the Bluetooth firmware using the files included in the newest Windows driver. My MD5s:
sonic@sonic-XPS-13-9370:/lib/firmware/qca$ md5sum *usb*302*
067fb95e8501bad2683df07d23539e7d nvm_usb_00000302.bin
b3e2784b16b5b0cf5defa7eb9115956d nvm_usb_00000302.bin_orig
c9d6334b547a92817458de10243f398c rampatch_usb_00000302.bin
86c377ab7b2c24cc12cea5e79f71d610 rampatch_usb_00000302.bin_orig
By the way, an easier workaround was to unplug the power and do a suspend/resume cycle.
And at least mine is a 1435 Killer.
