From Dilyn's steps, he install the beta version of the bluez, and here is what I found.

The snap runs well when using Ubuntu desktop 22.04 (all updates applied end of Jan 2022). We have tried using this same snap on Ubuntu Core 22 running on X86_64. On some hardware platforms (thinkpad E15 and x86 Mac) everything works as expected. We can install the snap on Jammy 22.04 or Core 22 on these platforms and get expected functionality regardless of OS. On our targeted platform (a Dell 5570) things are not working. When running 22.04 Jammy, everything works. When running Core 22, some advanced bluetooth functionality is not available. Since the Core 22 image installs and runs on other X86_64 hardware we suspect a device driver issue. Attached are several files taken from the Dell 5570 1) dmesg from Core 22. 2) dmesg from Jammy 22.04 3) output of lspci from Jammy 22.04 4) Output of lsusb from Jammy 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/2006517/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
