offload support failed

[pvanderlinden]

I have updated bluez recently, and this caused constant disconnect/connect cycles. After trying to resolve this I have no working bluetooth at all. Connections just fail

This might be the main issue, as this is constantly being logged while connecting:
src/adv_monitor.c:btd_adv_monitor_offload_supported() Manager is NULL, get offload support failed

Eventually:

 bluetoothd[1004]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for F8:DF:15:39:E4:FE: Protocol not available
 bluetoothd[1004]: src/service.c:btd_service_connect() a2dp-source profile connect failed for F8:DF:15:39:E4:FE: Protocol not available

Versions:

• bluez 5.63-1
• linux 5.16.5 and 5.15.19

I tried completely removing the device and reconnecting as well.

After downgrading to 5.60-1 the error was gone, but now I'm back at missing a2dp profiles.

I'm still assuming this was caused by the upgrade of bluez. I managed to get it working to downgrade my system (which was in need of an updated), the know good versions:

• linux 5.15.13.arch1-1
• pipewire-pulse 1:0.3.43-1
• bluez-git 1:5.62.r89.gb6061ea5b-1

I was encountering the same issue (this message being spammmed + BT audio not working at all). Just downgrading the kernel to the version you mentioned restored audio even when keeping pipewire and bluez-git (19448b9) at latest. It's still spamming src/adv_monitor.c:btd_adv_monitor_offload_supported() Manager is NULL, get offload support failed, but audio is working nevertheless. I think these are two unrelated issues.

With the older kernel and older bluez I still had the profile issue though? I might try to upgrade everything but the kernel to see if it is still functional after that the coming week.

I just tried this with my old laptop. did a full update:

• bluez 5.63-1
• linux 5.16.7
  It worked, but the logs are constantly spamming the bluetoothd message src/adv_monitor.c:btd_adv_monitor_offload_supported() Manager is NULL, get offload support failed
  I thought after installing bluez-git, it was resolved (bluez-git 1:5.63.r34.g19448b9cb-1), but it just seems to happen a little bit less often

mainly after starting the blueberry. The error is still coming from bluetoothd, so I think it's still an issue within bluez rather then blueberry.

Can confirm: after updating kernel to linux 5.16.7 BT audio is generally working again, but the error is still flooded as long as I have Gnome's bluetooth settings open.
