Title:
Bluetooth works on desktop but not on ubuntu core
Status in bluez package in Ubuntu:
Confirmed
Bug description:
We have built a snap that uses some bluetooth functionality.
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
