>From the dmesg logs, the kernel you use on desktop(5.15.0-56) and on core(5.15.0-58) are not the same, but I've checked the kernel logs, there is no update on bt driver part between the 2 kernel versions. It'd be good if you can help me to update the kernel to make sure the kernel versions are identical and check the issue again.(I feel the result won't change)
The snap package works on desktop, but not on core, this doesn't look like a kernel/driver issue. Could you provide more info about which function call failed? or provide a simple program that we could try on our side? BTW, the difference between the dmesg logs is that rfcomm is loaded on the desktop, but not on the core system, could you also try to load it on the core system to see if it makes any difference, thanks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/2006517 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/2006517/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
