Bluetooth hardware not detected

VIM2 Ubuntu
1

Hello, lately I have been trying to setup homebridge on my khadas VIM2 when I noticed that bluetooth wasn’t working. The board literally looks like it’s not detecting the onboard bluetooth, and it won’t even work with generic usb dongles. If I connect one, lshw says that the device is UNCLAIMED.

hciconfig can’t find the device either :(.

Am I doing something wrong? I tried following the official guide here https://docs.khadas.com/vim2/HowToSetupBluetooth.html but I cannot bring up the device.
In /dev looks like it’s missing completely.
Is there anything I could do?

thanks in advance

Not for me :frowning:

I checked in /dev, I can’t find any device named hci-something

Ignore the fact that I am on ubuntu 20.04, I upgraded while trying to fix the problem. I had it on 18.04 too

@Firestorm7893 I think you can try this one firwamre https://dl.khadas.com/Firmware/VIM2/Ubuntu/EMMC/VIM2_Ubuntu-xfce-bionic_Linux-4.9_arm64_EMMC_V20191231.7z

And don’t install any software. Then try again.
