Hello elgato. I recently deployed a container(theengs gateway) using onboard bluetooth(AX201) on unraid 6.12.10 , hope my deployment process could be your reference.
The first thing you need to do is find the location of the bluetooth hardware, which is usually shown as a USB device. You can find it through Tools → SysDevs. For me it's /dev/bus/usb/001/005 and based on your screenshots, I'm guessing it's /dev/bus/usb/001/011
When you confirm the hardware pass-through parameters, add the device to your container setting and mount /run/dbus
Now you need bluez to providing the bluetooth protocol stack for unraid OS. It can be installed by nerd-tool plugin or un-get command.
Once the installation is complete, you will find that the bluetooth service is not activated, because the bluetooth module is disabled by default. To enable it permanently, you need:
1. Delete the lines in the config/modprobe.d/bluetooth.conf file in the USB boot drive with “bluetooth” and “btusb”
2. Add "/etc/rc.d/rc.bluetooth restart" to the config/go script file in the USB boot drive
If all goes well, bluetooth will be available for container after reboot.
Forgive me for my lengthy statements. If you have any doubts about the details of the operation, please let me know.
