Linux Mint 19 — No Bluetooth adapters found

Post by jaspergrond » Wed Dec 12, 2018 10:47 am

I have been using my new laptop (Dell XPS 15 9570) with Linux Mint 19 Cinnamon edition for a month now and bluetooth has been working flawlessly. Today I boot it up and the bluetooth app did not start automatically. I started the bluetooth app and the message «No Bluetooth adapters found» was displayed.

After some researching of the problem I could not find an solution for myself but did find some diagnostic steps I will present now:

This is the version of the kernel I am using. I have been using it since Nov 15th (I think, but for a couple of weeks at least) with no bluetooth issue until today.

$ uname -a Linux jaari 4.15.0-42-generic #45-Ubuntu SMP Thu Nov 15 19:32:57 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux 

$ lsmod | grep bluetooth; dmesg | egrep -i 'blue|firm' [ 0.043524] Spectre V2 : Enabling Restricted Speculation for firmware calls [ 0.244448] ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored [ 2.116716] [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_01.bin (v1.1) [ 5.381824] ath10k_pci 0000:3b:00.0: Direct firmware load for ath10k/pre-cal-pci-0000:3b:00.0.bin failed with error -2 [ 5.381831] ath10k_pci 0000:3b:00.0: Direct firmware load for ath10k/cal-pci-0000:3b:00.0.bin failed with error -2 [ 5.384210] ath10k_pci 0000:3b:00.0: firmware ver WLAN.RM.4.4.1-00079-QCARMSWPZ-1 api 6 features wowlan,ignore-otp crc32 fd869beb 

In a similar forum post viewtopic.php?t=212778 the previous step did not show an error message so they went a step further. However I do see an error message in reference to ath10k_pci and am not sure where to go from here. Any help would be greatly appreciated!

The 4.15.0-42 kernel just came available recently. If you still have the 4.15.0-39 (or older) Kernel installed, try selecting that kernel(s) from Grub menu for a test to see if the firmware errors occur.

While attempting to get the grub menu to show up (following viewtopic.php?f=90&t=183449#p951025 and failing) bluetooth started working again after a few reboots.
Not sure if this helps but now the lsmod output looks like:

My thinking now falls to hardware problem with bluetooth. Although I agree with JeremyB on the error being wifi, I’m still curious if the problem has any relationship to newer/newest kernel. You did say it’s a brand new laptop.

On not being able to see Grub boot menu, I assume you tried holding SHIFT key and that isn’t producing the boot menu. I know that change to GRUB_TIMEOUT_STYLE=»menu» on that same post you reference should work. However, I would also adjust the parameter GRUB_TIMEOUT= to something other than 0, e.g. 3.

Make sure you run sudo update-grub after the change.

You could try blacklisting one bluetooth module and then load it later to see if there is some firmware loading issue

echo "blacklist btusb" | sudo tee /etc/modprobe.d/btusb.conf

Thanks JeremyB, before I do anything I want to make sure I know what I am doing.

Does the tee command write «blacklist btusb» to /etc/modprobe.d/btusb.conf thus blacklisting the btusb module?
Then, modeprobe manually loads the module?
Afterwards when I want to unblacklist it do I just edit /etc/modprobe.d/btusb.conf and remove the «blacklist btusb» line?

Also, is observing what happens when the module loads what we are trying to accomplish here now that the problem has ceased to show itself? Will modprobe return an error to the terminal if something is wrong?

If it works, I would not delete the blacklist until a different solution can be found. I think it might be an issue with the timing of the firmware load

Sorry for the delay, had to wait for the problem to reappear.

Blacklisting and reloading does not seem to work. After following your instructions (rebooting, waiting and loading via «sudo modprobe btusb») still gets me the «No bluetooth adapters found» error in the bluetooth manager.

Since it did not work, do you recommend rolling back to the previous version of the kernel and seeing if the problem is fixed by that? I am on 4.15.0-43-generic and have the following kernels available to roll back to:

ii linux-image-4.15.0-38 4.15.0-38.41 amd64 Signed kernel image generic ii linux-image-4.15.0-39 4.15.0-39.42 amd64 Signed kernel image generic ii linux-image-4.15.0-42 4.15.0-42.45 amd64 Signed kernel image generic ii linux-image-4.15.0-43 4.15.0-43.46 amd64 Signed kernel image generic ii linux-image-generic 4.15.0.43.45 amd64 Generic Linux kernel image

Update: I went ahead and loaded 4.15.0-42-generic and bluetooth has now resumed working. I’ll keep note if the issue reappears on this kernel.

I just remembered 4.15.0-42 is what I started with. I guess I’ll go back one more to be safe. But note that changing kernels immediately fixed the problem (unless it was a lucky coincidence).

Bluetooth adapter not detected on Linux

I’ve been using Arch Linux for a while and bluetooth has been working without issues. Now, for no explicable reason, Arch doesn’t detect my bluetooth adapters anymore. I tried doing:
$ sudo systemctl enable bluetooth ,
$ sudo systemctl start bluetooth and
$ sudo systemctl start dbus . I’ve enabled generic bluetooth drivers:
$ sudo modprobe btusb . I’ve installed: bluez, bluez-utils-compat and blueman. $ sudo lsmod | grep bluetooth returns:

$ sudo lspci | grep blue returns nothing. $ sudo hciconfig returns nothing. $ sudo hcitool dev returns:

Bluetooth: no adapters found

I’m using a Bluetooth keyboard and all was working fine, until today. It stopped working. My Bluetooth applet says ‘No adapters found’. I’ve got a Asus UX303LA. When using sudo service bluetooth status , this is the output:
