Hi All,

 

I am not able to make the Bluetooth controller working on the IMX8M mini evk. I made an fsl-image-machine-test and test the wifi interface without any problem.

 

Here are the steps I made to make bluetooth working:

 

root@imx8mmevk: ~# systemctl start bluetooth

root@imx8mmevk: ~# hciconfig hci0 up

Can't get device info: No such device

root@imx8mmevk: ~# bluetoothctl

Agent Registered

[bluetooth]# devices

No default controller available

[bluetooth]# quit

root@imx8mmevk: ~# hciattach /dev/ttymxc2 qca
qca
frame_hci_cmd_pkt: Sending EDL_PATCH_VER_REQ_CMD

Anyone can help me?
