Has someone been able to get Bluetooth USB dongle working on SabreLite Nitrogen6x board in non Android builds?
I've been trying to achieve this with fsl-ubuntu (L3.0.35.1.1.0 / L3.0.35.1.1.1) and with Yocto build with these instructions How to test yocto for imx6 .
For me it looks like that rfkill soft blocking is being enabled due some automatic event, either from kernel or Bluetoothd.
I tried to build kernel without rfkill driver but then I'm not able to see any devices with hciconfig.
With quick look there is no build flag in Bluetooth driver to disable rfkill as there is in Andoroid.
I can see following behaviour when trying to set rfkill unblock all.
Initial Situation
0: hci0: bluetooth
Soft blocked: yes
Hard blocked: no
After rfkill unblock all
0: hci0: bluetooth
Soft blocked: no
Hard blocked: no
About 0,5sec after rfkill unblock all
0: hci0: bluetooth
Soft blocked: yes
Hard blocked: no
Below is the /var/log/messages for Bluetooth events

Hi Kari,
GaryCollins mentioned that he was successful by simply adding
CONFIG_HMIBTUSB=m into his kernel configuration and installing
the bluez-utils and bluez packages.
I don't know the details of what type of dongle he used though.
