Issues with Bluetooth: hci0: don't support firmware rome

[walkingzen]

Hello,

I am using Manjaro Deepin Testing and my Bluetooth is not working as expected. Even though Bluetooth service seems to be working, I could not see the Bluetooth icon in control center.
I have idVendor 0x0cf3 Qualcomm Atheros Communications idProduct 0x3004 AR3012 Bluetooth 4. and it seems to be due to this https://www.spinics.net/lists/linux-bluetooth/msg75196.html. PFB the

 dmesg | grep -i blue 
[   16.185533] Bluetooth: Core ver 2.22
[   16.185572] Bluetooth: HCI device and connection manager initialized
[   16.185579] Bluetooth: HCI socket layer initialized
[   16.185583] Bluetooth: L2CAP socket layer initialized
[   16.185595] Bluetooth: SCO socket layer initialized

[   27.616715] Bluetooth: BNEP filters: protocol multicast

I tried linux 44, 49, 414, and 416
I would really appreciate any help. As you can see the Bluetooth is not showing up in my control center.

A similar issue is raised by another member. So I think this could be ignored

Thanks @philm for reply. So you are saying that it is not fixed in upstream, right? I have given this same issue in the explanation. I didn’t quite understand the solution in bugzilla as in QC says it is not fixed. Am I missing something?

[walkingzen]

@philm I could get it working with linux 3.18. I know that I am going backward. But for time being, I think it would be better as I need to use my Bluetooth headset.

The issue is with commit f44cb4b and it was backported to all LTS kernels aswell. The solution is to revert this commit and apply this on top of it.

[philm]

Please try if this fixes the issue for you:

sudo pacman -U https://mirror.netzspielplatz.de/manjaro/packages/pool/overlay/linux416-4.16.6-2-x86_64.pkg.tar.xz

Thanks @philm. Sorry for the late reply as I was busy with some work yesterday.
I have installed linux416 (currently I have linux416 4.16.6-2) as you suggested and it is working fine. Thanks a lot.

I have checked after recent update on linux49 (linux49 4.9.97-1) and 414 (linux414 4.14.38-1) but they did not work.

Anyway, thanks a lot for the help.

[philm]

Thx for the feedback. The other kernels will have the fix on Wednesday. See here.

[philm]

I’d backported the patch to v4.4, v4.9, v4.14, v4.16 and v4.17 by now. You may find those updates today in unstable and soon in other branches too.

[walkingzen]

It worked for 4.9, 4.14, and 4.16 now. Thank you very much

so in order to fix it. i should install regular 4.16 kernel and apply the patch? thanks @walkingzen @philm

[FabricioLujano]

PERFECT! just perfect. i can confirm it is fixed now. Just installed the current 4.16.7-1 kernel and it works flawless. THANKS A LOT GUYS @philm @walkingzen
