Bluetooth not working in Ubuntu 16.04 with [0cf3:3004] Atheros adapter

Question

My laptop, an MSI GS70 Stealth Pro, has build a build in Bluetooth device that Ubuntu seems to not recognize.

When I go to System Settings > Bluetooth it says No Bluetooth adapters found.

From what I've seen in other threads, I leave here some hopefully helpful info:

rfkill list:

How do I fix this problem?

Solution

This problem exists because Atheros re-used the chip VID and PID.

See this bug report

As a workaround you can patch the btusb.c module and change it from ath3k to Rome.

I've built a DKMS package to fix this issue and uploaded it to my PPA.

https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth/+files/btusb-lp1542743-dkms_0.1_all.deb

Install this deb and reboot. This should fix the issue.

This is a QCA Rome chipset and it has the same bluetooth ID as an older bluetooth that is supported by the kernel. Qualcomm needs to find a way to fix this. This is the result from upstream about the device

[Pilot6]

I am building a DKMS package for this issue.

[Ricardo Rodrigues]

It fixed it right up! I've been without Bluetooth for such a long time. Thank you.

[Ricardo Rodrigues]

Update: for some reason, now the bluetooth works but it does not detect any devices. Last system update at 4th July. Should I hope another question?

[Pilot6]

Please post output of dkms status.

It looks OK. The problem is not related to kernel. It must be something user space.

[Ricardo Rodrigues]

What can I do to fix this? Should I rerun the commands up in the problems description and try to see if something changed?

[Pilot6]

It is hard to tell what happened. I added normal support to the module. Nothing has changed in kernel to break it.

[Ricardo Rodrigues]

It seams a shutdown and boot (and not a Reboot) did the trick.

[Pilot6]

So does it work now? If not add output of dmesg | grep -i blue to your question. I probably need to remove the ID from ath3k too.

[Ricardo Rodrigues]

It works now. The major problem now is on sleep or hibernation. Some times everything works fine after wake from sleep, other times it loses it's ability to detect devices.

[Ricardo Rodrigues]

Installed Ubuntu Gnome 16.10 and this deb no longer works. In the terminal I get this message: Building initial module for 4.8.0-26-generic Error! Bad return status for module build on kernel: 4.8.0-26-generic (x86_64) Consult /var/lib/dkms/btusb-lp1542743/0.1/build/make.log for more information.''

[Pilot6]

This deb was never intended for 16.10.

[Ricardo Rodrigues]

Then what do I do now?

[Pilot6]

Use 16.04 or patch it yourself. I do not support non-LTS releases.

[Dawoodjee]

Pls explain exactly whats happening here: { USB_DEVICE(0x04ca, 0x3011), .driver_info = BTUSB_QCA_ROME }, \n Are you simply prepending 0x to the ID values of the bluetooth device?
