I see that many people having problems around same things but I wasn't able to solve my problem by examining them. I bought a custom pc with rog crosshair x670e hero motherboard which has Intel AX210 as Blutooth adaptor and the supported driver seems to be installed. However I can't connect to bluetooth devices even tough they appear in the device list.

JBL Flip 5: It rarely connects and even if it connects it doesn't give sound or give out of sync and low quality sound

HP 350/355 multi-device-bluetooth-keyboard: Can't connect remains as "Not set up" in the list or gives a window that has the pairing number but dissappears in a matter of second.

Even if I manage to connect the keyboard, it would connect and disconnect rapidly then finally disconnect for good. I believe that is the reason why even If I connect the prompts on the screen is delayed or the key presses gets missed.

  • "firmware is "intel/ibt-0041-0041.sfi" which is different than the iwlwifi does this look wrong?" It does not look wrong. The ucode firmware is for the wifi and the sfi is for bluetooth. Normal. Welcome to Ask Ubuntu. – chili555 Oct 23 '23 at 15:32

  • Thank you @chili555! I tried the method from the link but I was unable to get any sound from the jbl or maintain a connection on the keyboard. – StarBoy Oct 28 '23 at 18:16
