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

The BT adv feature 1. works with 5.15 + bluez (20/stable) 5.53-7 2. doesn't work with 5.15 + bluez (22/beta) 5.64-3 3. (from Dilyn and Wendell) works with 5.19 + bluez (22/beta) It's still unclear why bluez requires specific version of kernel. Do we have a bluez expert to consult what kind of features the 5.15 kernel are missing?

@AceLan, In the comment #32 you were saying: "removed the beta bluez, and install stable bluez" It looks like you removed bluez that was from 22/beta track (bluez (22/beta) 5.64-3), and then installed one from 20/stable track (bluez 5.53-7 334 20/stable). You wrote that with that revision of bluez snap "power cycle the machine, and then advinfo works".

[Kernel-packages] [Bug 2006517] Re: Bluetooth works on desktop but not on ubuntu core
I assume that because you're using an x1 revision of the pc-kernel snap you're using the 5.15 image I produced? Note that I tested both 22/stable and 22/beta of the bluez snap and saw identical results for both revisions after multiple reboot cycles on both of them.

>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.

I'm not sure what your question means "Are you sure the function is lost?" The logging messages in this comment thread are from the logging from bluetoothd. We have our own software that we run at a later point that attempts to use the bluetooth adv_features, but it fails to find any adv_features available.

@Daniel, Those denials should be resolved by this PR (https://github.com/snapcore/snapd/pull/12496). The problem is if we run this snap in devmode, skipping over apparmor entirely, the root problem still exists. Namely, bluetooth does not function on the device. With the relevant interface changes made and the snap installed fully confined on the two devices Alex mentions above, the snap in question works fine.

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/linux/+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
[Kernel-packages] [Bug 2006517] Re: Bluetooth works on desktop but not on ubuntu core
This bug is for Core - so apport-collect is not available. Adding some more logging output in this comment. I believe our bug is a result of the logging at that says: src/advertising.c:read_adv_features_callback() Failed to read advertising features: Not Supported (0x0c) Our code does try to call the bluetooth adv_features. The same snap package does work when install on different hardware. Feb 07 23:50:34 ubuntu systemd[1]: Started Service for snap application bluez.bluez.

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/linux/+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
