How to setup an Odroid as bluetooth sink (bt init issue)

[Ocye]

Choose the generic title since I likely have more questions later.

But I'm failing with the first step, to enable bluetooth. After starting the service I get "Failed to read advertising features: Unknown Command (0x01)". Everything is up to date.

sudo systemctl status bluetooth
