P.S.: Please help and fix it! Mouse used bluetooth 4.0 low energy
Comment 1 Paulo Horta 2020-09-15 17:03:40 UTC
I have similar problem. Laptop is a Huawei D14 2020 R5 with RTL8822CE.
Modules loaded rtw88 and btrtl.

Cannot connect to Huawei Bluetooth mouse. The ID last digits are random (:0F or :0E). I don't know if it's suppose to do that. I cannot test another mouse.

I tested Bluetooth audio and in spite of working, sound break a lot, even very close to the laptop.

I also managed to send files from another computer, but had trouble sending from a mobile phone.

In summary, bluetooh is working but with flaws.

Thanks in advance.

Forgot to mention that I'm using kernel version 5.4.0.47 in Ubuntu and I also tested with 5.8.9. Problem persisted.

Huawei Matebook 13 2020 AMD running the 5.8.13-zen1-2-zen kernel on Arch Linux. Same problem. I added myself to the mailing list.

RTL8822CE 802.11ac PCIe Wireless Network Adapter
Comment 5 Vladislav Smirnov 2020-10-19 12:15:09 UTC
Got the same issue on Huawei Matebook 14 D 2020 AMD running 5.4.0-7642-generic on Pop_OS.
Comment 6 david.zakarias 2020-10-21 18:14:12 UTC
Same problem here on Redmibook 16, RTL8822CE, with Microsoft Modern Mobile Mouse.
Comment 7 julian 2020-10-23 09:50:38 UTC
On my machine (Huawei Matebook 13 2020 AMD), the btrtl driver does not seem to be used at all (btusb is used instead). The bluetooth device seem to use the 1358:c123 USB identifiers which are not listed in the blacklist table of drivers/bluetooth/btusb.c. Could this be the problem ?
Comment 8 julian 2020-10-23 09:52:58 UTC
Note that other RTL8822CE devices with different USB vendor/device IDs are present in the blacklist table.
Comment 9 julian 2020-10-23 22:00:59 UTC
I've patched my kernel to add the missing USB identifier and that seem to have solved the issue. I can now properly pair with a bluetooth mouse.

My dmesg now shows firmware files being loaded for the device:

[    5.909847] Bluetooth: hci0: RTL: examining hci_ver=0a hci_rev=000c lmp_ver=0
a lmp_subver=8822

[    5.918282] Bluetooth: hci0: RTL: cfg_sz 6, total sz 31422

What's the right way to go about this ? Should I submit my patch upstream ?
Comment 10 david.zakarias 2020-10-24 07:49:45 UTC
My device ID as shown by lsusb:

Bus 001 Device 002: ID 0cb5:c547 Realtek Bluetooth Radio

Both btusb and btrtl is loaded but I do not see the rtl8822 firmware being loaded in the dmesg output.

The wifi part of the chip works fine.

I’ve submitted this patch to the linux-bluetooth mailing list: https://patchwork.kernel.org/project/bluetooth/patch/20201023231748.56519-1-julian@pidancet.net/

David, i suggest you try to apply the same patch to your system, changing the USB IDs to what you’re seeing, and see if that solves your issue.

This is indeed the solution. Thanks.

I tried what Julian did, but things do not work. 

hciconfig hci0 shows:

If I start btmon, and do sudo hciconfig hci0 up, there's a huge amount of output, and an error at the end:

> I tried what Julian did, but things do not work. 

Julian's solution adds a device with id 1358:c123. As I can see from your previous message yours is 0cb5:c547. Did you change the patch?
Comment 15 david.zakarias 2020-10-25 14:04:56 UTC
Yes I did.
Comment 16 david.zakarias 2020-10-25 14:11:19 UTC
Also, in a sense the patch worked, as the firmware is now loaded on boot. But that's the only positive thing about it, as no (remote) devices are visible and it's impossible to bring hci0 up because of the error above.

Without the patch, the firmware is not loaded, remote devices ARE visible, but when I try connecting, it disconnects instantly, same org.bluez.Error.AuthenticationCanceled error as what OP is seeing.

Hi,

I got a similar error. 
I have a Huawei Matebook 14 2020 with Ryzen 4600H and the same RTL8822CE.  lsusb shows the following: 
Bus 003 Device 002: ID 1358:c123 Realtek Bluetooth Radio

I applied Julians Kernel patch and can see that the firmware is loaded during boot, but bluez does not detect the controller. 
dmesg | grep -i bluetooth:

Trying to bring the device up via 'hciconfig hci0 up' gives me the following error message: 
Can't init device hci0: Protocol not supported (93)`

Does anyone have any Ideas what I can do to get this working?
Comment 20 david.zakarias 2020-10-26 10:26:02 UTC
Is it possible that a newer firmware fixes the problem? I also have version 0x09993aa1. 
Julian what version do you have?
Comment 21 Niklas Frank 2020-10-26 11:26:43 UTC
Sounds reasonable. How would I update to a newer firmware version?
Comment 22 julian 2020-10-26 20:14:28 UTC
Bluetooth: hci0: RTL: fw version 0x09993aa1

Same version here.
Comment 23 Niklas Frank 2020-10-27 08:34:08 UTC
Too bad..
As you, Julian, are the one who has been able to fix the problem for at least some people, do you have any Idea what David and I might try out to get Bluetooth working for our devices as well?
Comment 24 julian 2020-10-27 08:58:58 UTC
I must admit I am clueless...

We should probably start by comparing Laptop models and distro used to see if a pattern emerges.

I’m running Ubuntu 20.04 on a Huawei Matebook 13 AMD 2020 laptop. I’ve applied my patch on top of the 5.4.0 Ubuntu kernel (linux-image-unsigned-5.4.0-52-generic). I’m happy to share the .deb files if someone wants to give it a try.

Hi David,

I ran into the same Set Resolvable Private Address error with my adapter, an rtl8761b. I submitted a patch here with my understanding of the issue: https://marc.info/?l=linux-bluetooth&m=160378222632366&w=2. Could you check to see if that patch helps?

I don't believe it is related to the original issue seen in this thread though.
Comment 26 david.zakarias 2020-10-27 18:37:21 UTC
Edward, many thanks! This patch solved the issue for me, my RTL8822CE and my BT mouse now works. I'll create a oneliner patch like Julian's with my device ID.
Btw this is on kernel 3.9.1.
Comment 27 david.zakarias 2020-10-27 21:32:20 UTC
I've sent the patch, see here: https://marc.info/?l=linux-bluetooth&m=160383198717911&w=2

Thanks alot! I am now able to connect to my Bluetooth mouse!

Although I notice that the bluetooth adapter still behaves weird. It sometimes simply stops working and I have to unload and load the `btusb` kernel module to get the adapter working again. 

As for Distro/Kernel Version: I am using Manjaro and I have applied the patches on top of Kernel 5.9.3

You need the source code to compile a modified kernel. If you have it you could just go in and edit the file in question manually (net/bluetooth/hci_core.c) or apply the patch with the patch command if you find it easier.

Hi,

are you on Manjaro as well? 
As Julian already said, there is information available online on how to compile your specific distros kernel. Just do a quick google search, read the instructions, make sure you understand what the commands are doing, and follow the steps. 

If you are on manjaro as well, have a look at the following forum post: https://forum.manjaro.org/t/how-to-compile-patch-kernel-with-custom-alsa-driver/20326

Thanks very match, sorry my bad English.
I am used arch linux and my mouse work now!!

1). I'm download source code linux (version 5.9.6)
2). Insert in PKGBUILD two patchs: onw from julian and two from Edward (thanks guys, good job)
3). Build kernel and install.

Hello,

I've resent a patch for 1358:c123 because the previous one did not apply cleanly. The patch eventually made it into bluetooth-next. I've got no idea when it's supposed to get into mainline.

It could be great if you can share your deb file. Thanks a lot :)

This patch does not resolve the issue of suspend/resume cycle leading to disconnected USB device and hence requiring reboot to get the bluetooth adapter back. https://bugzilla.kernel.org/show_bug.cgi?id=210141

Bus 005 Device 002: ID 13d3:3548 IMC Networks Bluetooth Radio

Bug report for this device here : https://bugzilla.kernel.org/show_bug.cgi?id=210453
Comment 42 Maksim Moskalik 2020-12-03 18:43:55 UTC
I have the same problem with the rtl8822ce.
The patch does not solve the problem completely, there remains bug after hibernation.
Comment 43 Maksim Moskalik 2020-12-11 12:00:53 UTC
I checked on kernel 5.9.12 Ubuntu 20.04 Huawei amd D13, problem not solved
Comment 44 Olivier V 2020-12-11 18:44:16 UTC
I'm happy for you and your rtl8822ce firmware...

But still bluetooth not working for rtl8822cu in 5.9.12.
Comment 45 Luis 2020-12-12 01:00:28 UTC
Confirmed that worked mixing julian@blk9.net and Edward Vear patches.

I have a Matebook D15 with Elementary OS and kernel 5.9.12 (now patched).

Thanks a lot for all the efforts. Spent several days searching for the solution.

Regards,

LC

@Luis: do the patches make it work with suspend-resume cycle? Are you able to see your bluetooth devices after resuming from suspend?
Comment 47 Olivier V 2020-12-12 08:10:53 UTC
Is it necessary to apply the patch myself ?
How to do this (exact steeps) ?

Thank you?

I bisected the bug on the rtl8822ce here : https://bugzilla.kernel.org/show_bug.cgi?id=210453

It seems to bee the same problem linked to "rpa".

Yes, it works with suspend and resume.

So far the only details that keeps bothering a little, it is sometimes the mouse (Microsoft Modern Mobile Mouse Low Energy) stays frozen for a second or two, and then gets back to work. Happens 3 or 4 times a day, but haven't been able to cathc any error message in syslog yet.

Also tested wit other two devices connected simultaneously, the mouse itself, bluetooth B&O speaker and cell phone Huawei P40 pro.

That's all I've checked this last 2 weeks.

Comment 55 julian 2021-01-11 16:14:14 UTC
Olivier,

Are you sure the problem is really gone in 5.10.6 ? I don't see my patch anywhere on the 5.10 branch.
Comment 56 Olivier V 2021-01-11 16:19:47 UTC
Yes I'm sure.

meloli@Asus-A17:~$ uname -a

And bluetooth working.
Comment 57 Vladislav Smirnov 2021-01-11 17:08:59 UTC
I couldn't find a corresponding change in the diffs too.

Here https://bugzilla.kernel.org/show_bug.cgi?id=210279#c14

Paul Wise said : "Sudip Mukherjee requested inclusion in stable, so it will likely get into v5.10.6".
Comment 60 julian 2021-01-11 19:17:50 UTC
Olivier,

This ticket is about Bluetooth not working on certain laptop models using a RTL8822CE device because the firmware does not get loaded. The fix for this bug is there: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/bluetooth/btusb.c?id=f496297e76a69db7b52257898570bd38b8b9c92b

The change you refer to is a fix for a different bug that some of the users experienced while testing the patch above.
Comment 61 Olivier V 2021-01-11 19:20:23 UTC
OK. Sorry for the mistake. :)
