Hi ,

qca6173 Bluetooth and wifi support could be added to imx8. Wifi is ok, for bluetooth.

When edited /etc/systemd/system/bluetooth.target.wants/bluetooth.service

to add

ExecStartPre=-/usr/bin/hciattach /dev/ttymxc2 qualcomm

Bluetooth on status bar is up, could slide the bluetooth enable button in settings. Could sync the contacts, send/receive  messages,  play media files from mobile paired,

I could call phone  numbers from UI but no bluetooth audio is coming on the audio jack output during the call.

There is some issue with audio, as it breaks frequently when played on BT media player.

Also sometimes the responses from AGL UI is slow. Seems a performance issue, some kind of error logs are coming on journalctl -f. Not sure if its issue with BT drivers modules loaded or the another issue with AGL. Seeing error related memory buffers, please provide some pointers. 

Attached the debug log file..
