Bluetooth random disconnects intel(R) AX200

[spbisc97]

Hi, I have an intel AX200, and while the wifi works perfectly, the Bluetooth randomly disconnects from devices. This seems to be a common error that intel has fixed a few days ago: Reddit Broken ax200

It is possible to add those fixes in the package?

Thanks!

I have fixed this issue using the original Linux Firmware Just 3 commands

git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware 
sudo make install 
systemctl reboot 

this updates the files relative to mainline

I think this could be solved also by merging the updates of the original Linux-Firmware into this.

PS. I think the problem is the iwlwifi-*-62.ucode microcode files. Going back to 59 fixes this problem and doesn't add any. I have been using this for 3 days, I'll post if I see any.

The specific file for AX200 is iwlwifi-cc-a0-62.ucode -> iwlwifi-cc-a0-59.ucode

UPDATE 3: Here's the log of bluetoothctl, it's more detailed

UPDATE 2: bluetoothctl tells me that the device goes idle (of course, it should go idle once nothing's played) and it's after a few seconds that everything starts to break.

UPDATE: I've manually updated the firmware, substituting the "intel" folder with the newer one, but the issue apparently isn't the firmware, BlueZ isn't the cause and it all happens when the Dualsense gets connected too.

If I connect the Dualsense before I can't connect to the headphones. If I connect it later the headphones will eventually disconnect:

I have the same problem, I just migrated from the Intel 3168, to the Intel Killer 1675 (Intel AX210).

I had this random bluetooth disconnection with the other one, but I have this issue with the AX210 too... Digging out of desperation everything points to "linux-firmware".

Also, the issue becomes even more severe if I try to connect the Dualsense controller after connecting my SONY-WH1000XM5.

Pinging @mmstick for visibility or something. This has been happening for a month, since I finally had a use for Bluetooth audio in my laptop, when I bought the headphones.

The Dualsense never disconnected spontaneously. At least (if we don't count the endless advantages of this new network card over my old one) I have one less problem: if they randomly disconnects now the bluetooth doesn't "die" (I had to restart the computer to make it work again, now I just can't connect them anymore, or it's very hard).
