Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

I'm technically running artix, though I have managed to downgrade my kernel to this and get bluetooth back. It's not a good fix, but it did work. This also works on arch.
Linux amy 5.8.14-arch1-1 #1 SMP PREEMPT Wed, 07 Oct 2020 23:59:46 +0000 x86_64 GNU/Linux

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

no working neither in 5.9.8 ...

I was testing if it works with lts kernel and it does, the problem is that other problems appear since is a very new laptop... gotta stick to the linux kernel hoping the bluetooth problem gets fixed

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

This issue also affects devices with ID 0bda:b00c on every 5.9 kernel.

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

Is this related to https://bugzilla.kernel.org/show_bug.cgi?id=209403 and https://bugzilla.kernel.org/show_bug.cgi?id=209403 and https://bugzilla.kernel.org/show_bug.cgi?id=208765

Maybe adding some additional comments to one or other of these would be worth doing?

I honestly tried but don't really know how to do complete it ... didn't made much effort since the patch is for another card

After obtaining the PKGBUILD you add the patch to the source and checksum arrays with the following change:

diff --git a/trunk/PKGBUILD b/trunk/PKGBUILD

 export KBUILD_BUILD_HOST=archlinux
 export KBUILD_BUILD_USER=$pkgbase

The linux PKGBUILD will apply the patch without further changes.  Then build the package,  which can take hours.
You can also try linux-mainline Unofficial_user_repositories#miffe to see if 5.10-rc4 has fixed the issue.

Not fixed in linux-5.10-rc4

# ~/D/linux-5.10-rc4> grep '35] & 0x40) {' net/bluetooth/hci_core.c
		if (hdev->commands[35] & 0x40)

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

It's realtek chip, but different number, but the bug affects several different controllers.

is your card the rtl8822ce?

Tried this patch and got BT working, with rtl8822ce.

Do you have any idea when this will be added to the "default" kernel.

Is this is good enough to mark the thread as solved?

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

There has been no response to the mailing list post of the patch.  Once it is accepted into someones tree it will become easier to guess which kernel the patch will land in.
Edit:
It is your choice when to mark the thread solved.

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

Hello, So today I downloaded source code of Linux from kernel.org , extracted it and then changed that buggy line in net/bluetooth/hci_core.c line 766

change it from     if (hdev->commands[35] & 0x40) {
to                          if (hdev->commands[35] & 0x04) {

now follow guide at https://wiki.archlinux.org/index.php/Ke … ompilation   
I didn't use build system because of too  much to download and i can't do it for now.

I can use my card now, and it works well <3 much smoother , Have fun.

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

The patch isn't needed in 5.9.11 (at least for me) A bit weird since i don't see anything about it in the changelog.

Re: [SOLVED] Bluetooth not working with rtl8822ce and kernel 5.9.1

It seems that the patch is being followed up - and there was an additional comment by one of the developers on the patch that you can follow at https://patches.linaro.org/patch/310710/ so hopefully this will get into the kernel tree before too long.

The patch is not implemented in 5.9.11... I still have the same problem with bluetooth in 5.9.11, maybe you had another problem not related with this rlt8822ce, glad to hear it's working for you now

It was added to the -next tree after Linus had completed all the feature pulls and tagged 5.10-rc1 so unless it part of a fix pull request it will be part of 5.11 then back-ported to 5.10.Y stable series.
It could be added to the Arch linux package before that,  open a bug request on the Arch bug tracker or talk to heftig on IRC.
