Bluetooth is not working


We are working on Imx8 NXP board and trying to port Fedora-IOT on the same.

We have extracted the Fedora-IOT rootfs from the raw image Fedora provides for Rpi3 board. We are able to up the NXP-imx8 board with Fedora-IoT rootfs. We are not able to connect to the BT device.

Please help to resolve.

Is there any information in dmesg that provides any hints as to the problem, did the firmware load? Does “bluetoothctl show” show the controller in a reasonable state with valid MAC address?
