I am going to try to bypass Qt Bluetooth.
I have implemented "bluetooth" library , however I am stomped how to instruct Qt to process hci calls directly.
I am using this doc as a "template"

https://people.csail.mit.edu/albert/...ntro/c404.html'

dev_id = hci_get_route(NULL);
'
The above call does not compile, even after I installed libbluetooth-dev

What am I missing to be able to use "hci" ?

Any help would be greatly appreciated.
