No bluetooth hci0 interface getting detected for Raspberry Pi Compute Module 4.

[indrajeetshirole2407]

We are trying work on Bluetooth on Raspberry Pi Compute Module 4. We are running Poky (Yocto Project Reference Distro) 3.1.13 on Raspberry Pi Compute Module 4. We are using dunfell branch for meta-raspberrypi.

We are not able to see the bluetooth interface hci0 if I type hciconfig command.

root@wacout:/# hciconfig
root@wacout:/#

I don't see any devices if I type hcitool dev command

root@wacout:/# hcitool dev
Devices:
root@wacout:/#

If I try to run systemctl start hciuart.service command, it fails with Initialization timeout error.

Any idea how to fix these error?

I will highly appreciate your help

Does bluetoothctl power on help?

Thanks for the reply, I ran the command but it says no default controller available

root@wacout:~# bluetoothctl power on
