hciattach /dev/ttymxc2 qualcomm
But When I use this command with baud rate and flow as below, the bluetooth interface does not come up at all. What's going wrong ? how to set the baud rate ?
hciattach /dev/ttymxc2 qca 3000000 -t 30 flow
I can give you a little help with BT work.
I use imx8mqevk and wifi, bt module is qca6174a (onboard type)
Did you add firmware for qca6174a 's BT?
