Bluetooth not working since kernel 5.11.1 (and still as of 5.11.12)

I cannot even turn on the bluetooth. The journalctl shows:

kernel: Bluetooth: hci0: BCM: failed to write update baudrate (-16)
kernel: Bluetooth: hci0: Failed to set baudrate
kernel: Bluetooth: hci0: BCM: firmware Patch file not found, tried:
kernel: Bluetooth: hci0: BCM: 'brcm/BCM.hcd'

When downgrading to linux-5.10.16 all is good. Any idea how to fix this?

Have a look at https://wiki.archlinux.org/index.php/Bl … ernel_5.10

Basically, you have bluetooth on your wifi card via USB. (internally it's connected like that) This is causing problems at the moment with latest kernel. Solution is to apply specified in wiki patch, maybe it will help, or to run an older kernel, perhaps LTS. Third solution is to install into your laptop separate bluetooth module, this requires some hacking around, sometimes you just have to buy cable and module, other times you have to make your own cable and solder to mobo's internal usb channel. I have such setup, essentially I have 2 bluetooth adapters, one on wifi card and one separate. Mobo's always have a place on them to where you can connect or solder to a usb adapter, doesn't matter if it's bluetooth or an LTE modem.

Let me know if that patch works, I haven't done it myself yet.

That wiki page says kernel 5.10 had problems, and it was fixed in 5.11.
5.10 works fine for me. My issue is with kernel 5.11.

Seems like others have similar problems with 5.11.
Though my problem seems to be worse: simply no way to turn on bluetooth on kernel 5.11.1.

What kernel do you think I have? Kernel   5.11.1-xanmod1-1 + stock arch and zen flavors.
I'm having this same issue. Was it fixed? My bluetooth on wifi card does not work. When I boot into LTS 5.4 kernel it works. No it wasn't fixed. They lying. Look, either apply the patch or drop to LTS kernel, the problem is the kernel, you can confirm it by building an LTS kernel and booting into it.

That particular problem the patch addresses should be fixed by upstream with 5.11.2: https://git.kernel.org/pub/scm/linux/ke … 11.2#n4068
I have no idea why someone claimed 5.11.arch2 fixed it.
Edit: Oh right. arch patches, not upstream.

Please do try applying the above patch that has already been applied and confirm it fails to apply.  If you have an issue with Bluetooth on the above kernels then it is a different issue.  There is no reason for anyone to lie about what is included in the kernel which is easily verifiable.

Re: Bluetooth not working since kernel 5.11.1 (and still as of 5.11.12)

The problem still persists with 5.11.12-arch1-1 kernel.
Bellow is all I see in journalctl --boot related to bluetooth. Any help would be appreciated.

The error ones seem to be only:

09:24:44 kernel: Bluetooth: hci0: BCM: failed to write update baudrate (-16)
09:24:44 kernel: Bluetooth: hci0: Failed to set baudrate
