Intel 8260 Bluetooth not working

[MAshby]

Expected behaviour:
I can enable bluetooth in the system settings, and pair with my other devices.

Actual behaviour:
Always displays as 'off' in the settings dialog, and won't turn on.

Bluetooth worked on the same machine with previous Ubuntu releases (18.10) & no hardware changes.

"dmesg | grep -i bluetooth" reports the following:

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Daniel van Vugt (vanvugt)]

The attached RfKill.txt seems to suggest that Bluetooth is only turned off in software. So maybe this is just a gnome-shell GUI bug, or gnome-bluetooth.

To confirm this, please try turning it on by running this command in a terminal:

  rfkill unblock 0

[Daniel van Vugt (vanvugt)]

If the above command doesn't work then I would next focus on a possible kernel problem in:

[ 14.503899] Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi
[ 14.558347] Bluetooth: hci0: Failed to send firmware data (-38)

[Kai-Heng Feng (kaihengfeng)]

Please test this kernel:
https://people.canonical.com/~khfeng/lp1832988/

[MAshby (mfashby)]

Hi Daniel & Kei-Heng, thanks for the suggestions.

rfkill doesn't do much
> martin@martin-N15-17RD:~$ rfkill unblock 0
> rfkill: invalid identifier: 0

I'll try the kernel you suggested next.

[MAshby (mfashby)]

Kai-Heng: thanks for the suggestion, bluetooth now switches on & I can pair with devices.

Output of "dmesg | grep -i bluetooth" looks healthier too:

I guess the next time there's a kernel update for Ubuntu though it will wipe out the one you provided?

[Kai-Heng Feng (kaihengfeng)]

Before sending my fix upstream, can you test latest linux-firmware?
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

[MAshby (mfashby)]

Hi Kai-Heng,
I'd love to try that out, however there's no installation instructions I can see & google isn't being helpful.
Could you direct me to some install instructions?

[Kai-Heng Feng (kaihengfeng)]

$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/
$ sudo cp linux-firmware/iwlwifi-8000C-36.ucode /lib/firmware/
$ sudo reboot

[MAshby (mfashby)]

Thanks Kai-Heng,
I installed the latest firmware as you described and bluetooth works.
Please note I didn't uninstall the custom kernel from before. I don't know if this matters.

[Kai-Heng Feng (kaihengfeng)]

The custom kernel has a fix for this particular issue. Please use the default kernel to test latest firmware.

[MAshby (mfashby)]

I re-installed the default kernel using the following command:
$ sudo apt install --reinstall linux-image-5.0.0-20-generic
then installed the latest linux-firmware as directed above,
and now bluetooth is broken again, same as before. I guess this means that your fix is required Kai-Heng.

Thanks for the assistance

[Kai-Heng Feng (kaihengfeng)]

https://lkml.org/lkml/2019/7/17/116

[Kai-Heng Feng (kaihengfeng)]

Can you please boot Ubuntu with default kernel, and with kernel parameter `usbcore.dyndbg=+p`, reproduce the issue, and attach dmesg?

Thanks.

[MAshby (mfashby)]

Hi, sorry for the very late response.
This now appears to be working with the stock kernel. I'll post version details later

[Ivan Anishchuk (anishchuk-ia)]

Still failing with the same error on latest Eoan (kernel 5.3.0-40-generic). Dmesg with default kernel and usbcore.dyndbg=+p attached.

[Ivan Anishchuk (anishchuk-ia)]

As a workaround I'm currently doing rmmod btusb && modprobe btusb after every boot which seem to do the magic. Attaching the dmesg for that just in case.

[Kai-Heng Feng (kaihengfeng)]

Can you please test Focal daily:
