I have tried this with Ubuntu 22.10 and 23.10.
The output of uname -a is

Linux linuxwkstation 6.6.16-060616-generic #202402051536 SMP PREEMPT_DYNAMIC
Mon Feb 5 21:11:50 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

I am running on a MacMini 2014.
I went through many StackExchange posts and other sources to get bluetooth to work correctly. Hit and miss, as well as unreliable. Too many hours spent without result. The headphone sometimes worked or iPhone could not connect, etc.

I migrated to the latest kernel 6.6.16 - the latest Ubuntu is behind 6.5.0-10.10. The big difference is the improvements made in respect to bluetooth in 6.6.0 onwards.

Now, if I switch on my Bose headset it connects immediately, and I can conference or listen to music, as well as switch devices via the bluetooth utility.

    The link : Bluetooth does not work on Ubuntu 22.04 – user68186 does not work, for the very reason given in the "Answer to the question". The kernel used in the example is deficient in support of bluetooth (and as described as a focus area in kernel 6.6). By upgrading the kernel, as described, the issues are usually resolved. – dev OpenID Feb 07 '24 at 20:18
  • Ubuntu 22.10 (along with all flavors) is End-of-Life and thus unsupported on this site (https://askubuntu.com/help/on-topic), and many other Ubuntu sites, unless your question is specific to moving to a supported release of Ubuntu. https://fridge.ubuntu.com/2023/07/27/ubuntu-22-10-kinetic-kudu-end-of-life-reached-on-july-20-2023/ The kernels you mention aren't Ubuntu supported kernels either so your details are vague; 6.5 is the 23.10 kernel with other OEM options; 6.6 is the current noble kernel & 6.8 the testing noble kernel, with Ubuntu noble off-topic until released – guiverc Feb 07 '24 at 20:54

I migrated to the latest kernel 6.6.16 - the latest Ubuntu is behind 6.5.0-10.10. The big difference is the improvements made in respect to bluetooth in 6.6.0 onwards.

Now, if I switch on my Bose headset it connects immediately, and I can conference or listen to music, as well as switch devices via the bluetooth utility.

  1. Step One:

    sudo apt-get update
sudo apt-get upgrade
OPTIONAL: reboot (best practice?)

  2. Step two:

    sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt-get install mainline

  3. Step three:

    • Press "Show Apps" AND
    • select Mainline Kernels AND
    • wait for loading of all kernels AND
    • select 6.6.16 (No higher than this!!! Latest at this point in time. Later versions are NOT supported/production ready) AND
    • select Install and wait for the process to be completed AND
    • select Exit THEN
    • reboot

And now your bluetooth problems should be resolved!
