Enabling bluetooth on OE 410c

Hello, I am trying to enable the bluetooth on a OpenEmbedded build I compiled from this source:
https://github.com/96boards/oe-rpb-manifest.git -b jethro

I tried to start the bluetooth service like this:
systemctl start bluetooth

But I dont see any devices when I do:
hcitool dev

Does any1 have more info on this for the dragonboard410c ?

What is the status of the bluetooth on Debian/OE ? and how do we start it ?

use bluetoothctl
#power on
#agent on
#scan on

Anybody knows how to setup to serial mode ?
