PVE 7.4 + Home Assistant: Intel AX200 Bluetooth issues

[andy_e]

I recently set up a mini PC to run Home Assistant and it's my first time running Proxmox. Everything appears to be working well except when I boot the machine from a cold start (doesn't happen very often). Proxmox and Home Assistant start, but the AX200 Bluetooth looks like it has problems starting immediately. Here's the relevant dmesg -T output:

Home Assistant will start, but sees problems with the bluetooth adaptor:



Home Assistant won't be able to use its bluetooth integration or talk to any bluetooth devices until after a full shutdown and restart.

From the logs, it appears that the AX200 initially boots fine, firmware loads but then the device is reset and it fails subsequently. Does anyone know what the problem could be here? Failing that, is there a way to delay starting the HA VM until after the AX200 is working properly?

Absolutely same situation for Intel AX210

Same for me with the AX200 chip.
Anyone find any solution to this?

I seem to have the same problem.
PVE 7.3-3 and Bluetooth 9460/9560 Jefferson Peak (JfP).
Still no solution?

[stooovie]

I had the same adapter and Home Assistant work for almost a year, and it just started to silently fail the last week (December 2023) where there was no update to anything. Only a node reboot fixes it, which is supremely annoying. No fix so far.

 

[andy_e]

I think I've finally solved this. Bluetooth on Home Assistant has survived several reboots where it would normally fail over 50% of the time.

The errors in the `dmesg` output are all red herrings. Those errors are present even when it works. The problem comes from the host (Proxmox) fighting Home Assistant for control of the bluetooth USB device, even though it has been marked as a passthrough device. If Home Assistant OS is able to get control of the bluetooth device, it retains it until the next OS reboot. Otherwise, Proxmox has control and Home Assistant OS cannot access it.

The solution is to disable Bluetooth-related modules on the host operating system. Go into the shell for the host and check the `lsmod` output to see something like the following:

root@proxmox:~# lsmod | grep btusb
Module                  Size  Used by
btusb                  57344  0
btrtl                  20480  1 btusb
btbcm                  16384  1 btusb
btintel                28672  1 btusb
bluetooth             577536  5 btrtl,btintel,btbcm,btusb

From here, you can blacklist btusb to stop Proxmox initializing the device before Home Assistant OS. Add a the line blacklist btusb to /etc/modprobe.d/pve-blacklist.conf. Finally, reboot and bluetooth should work perfectly from now on.

Good call. Looking good for 24 hours now. Thanks!

Thanks, this really helped me! I was having trouble getting the integrated BT to work in NUC10FNH for Home Assistant running in a VM. Finally it works! Thx!
