--- Comment #7 from julian@blk9.net ---
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 ?

Note that other RTL8822CE devices with different USB vendor/device IDs are
present in the blacklist table.

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
[    5.912751] Bluetooth: hci0: RTL: rom_version status=0 version=3
[    5.912754] Bluetooth: hci0: RTL: loading rtl_bt/rtl8822cu_fw.bin
[    5.918147] Bluetooth: hci0: RTL: loading rtl_bt/rtl8822cu_config.bin
[    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 ?

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.

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

hciconfig hci0 shows:

hci0:   Type: Primary  Bus: USB
        BD Address: 80:30:49:1B:82:2C  ACL MTU: 1021:6  SCO MTU: 255:12

        RX bytes:2068 acl:0 sco:0 events:189 errors:0
        TX bytes:32660 acl:0 sco:0 commands:189 errors:0

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

< HCI Command: LE Clear White List (0x08|0x0010) plen 0    #59 [hci0] 38.597768

        Status: Unsupported Remote Feature / Unsupported LMP Feature (0x1a)


I'm stuck, any ideas?

--- Comment #16 from david.zakarias@gmail.com ---
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:
[    1.720939] usb 3-3: Product: Bluetooth Radio

[    4.196057] Bluetooth: BNEP socket layer initialized
[    4.371968] Bluetooth: hci0: RTL: fw version 0x09993aa1

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?

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 from julian@blk9.net ---
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.

I had the same problem, patch worked for me. Thank you! Can confirm it now
works on 5.9.1.

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.
