Bluetooth integration failing to initialize

[rahulpdev]

The problem

After working seamlessly for nearly two years a couple of days ago my bluetooth integration has stopped working and I can see that the integration is failing to load. The only event that has occurred during this time is that my area suffered a power cut that caused full power loss to my house. My Home Assistant Yellow and HAOS are otherwise working as normal since that event and I have a Avantree DG40S USB Adapter connected to the Yellow via a USB 2.0 cable.

What version of Home Assistant Core has the issue?

core-2024.5.3

What was the last working version of Home Assistant Core?

core-2024.5.3

What type of installation are you running?

Home Assistant OS

maybe the USB adapter died :thinking: try connecting the adapter to any other PC and check it it will be detected as Bluetooth device

[Dwarfex]

Happens to me on the yellow

[mib1185]

@Dwarfex any further information? Same usb adapter? same circumstances with power outage?

[Dwarfex]

@mib1185 pretty identical painting -

thus no known power outage and no further devices added via the integration

with the builtin cm4 bluetooth module from the yellow

Edit: did a complete reboot, problem seems to be gone for now -> will double check

00:00:00:00:00:00 means the mac address can't be read which means is either a hardware problem, driver/kernel (operating system) problem. You'll have better luck getting help on discord in #bluetooth since this repo is for core issues so you likely won't get help with that here.

@bdraco aye - thx ... so more a duplication of #92379?

Maybe. The original kernel bug that was for that one has been fixed (at least with HAOS), but there are obviously more.

@mib1185 I plugged the DG40S into my laptop and windows is picking up the bluetooth device. I also purchased a DG45 and switched it out with the original adapter on my Yellow, just to see what happens, and experienced the same outcome. I've tried deleting the bluetooth integration in HAOS and then reinstalling the integration and reconnecting the adapter but HAOS now returns the message "No unconfigured Bluetooth adapters found. There are 0 ignored adapters."

[mib1185]

@rahulpdev there were some kernel bugs in HAOS, which are solved (see https://github.com/home-assistant/core/issues/121961#issuecomment-2234012155). You may need to update your HAOS first and maybe also HA Core. But as @bdraco mentioned in https://github.com/home-assistant/core/issues/121961#issuecomment-2234005045 you should look for support on our chat server or forum.

@mib1185 updating HAOS seems to have done the trick thanks! It looks as though if I want to avoid such problems in the future I would be better off using Bluetooth proxy? I'm totally new to the concept of Bluetooth proxy but since I have only four BLE devices it seems a feasible solution.

[mib1185]

As you got the issue solved by updating tha HAOS, I'm going to close this issue report. If you still need support in Bluetooth topics, feel free to join our chat server or forum, thx 👍
