iMX8MM DDR4 EVK Bluetooth

I am using iMX8MM DDR4 EVK and imx-full-image from L4.14.98_ga_images. But the bluetooth adapter shows no device. I have the bluetooth modules/bluez in config file and the modules are available. I tried to add using hciattach as from https://community.nxp.com/thread/503438 but still no avail. Is there anything else we are missing. Thanks

Hi JimmyChan,

Got the details from Cypress the actual command to use will be

hciattach /dev/ttymxc0 bcm43xx 3000000 flow -t 20

Thanks & Regards,
