Hi everyone.


Do I need any special settings to use Bluetooth on 8MMINILPD4-EVK?


I bought 8MMINILPD4-EVK last week, and I bitbaked "fsl-image-qt5-validation-imx" (4.14-sumo). 

I did some functional checks, but I noticed that bluetoothctl returns "No default controller available".

root@imx8mmevk:~# bluetoothctl
Agent registered
[bluetooth]# devices
No default controller available
[bluetooth]# scan on
No default controller available
[bluetooth]# power on
No default controller available
[bluetooth]# version
Version 5.49
[bluetooth]# quit


I think that some settings are missing, does anyone know correct settings?
