Nope i only know big machinery like treadmills and bikes :D Anyway i solved the issue, in a dirty way but i solved it: i simply removed the reading from the discovery phase in the Qt framework ;) I really don't need them :) So i guess you should simply add a new function or a parameter to configure this behaviour. I will post the hci snoof in a new bug report. I didn't put here my patch because i think it's too dirty to share :D Have a nice weekend Andreas, and thanks again for your work! R.
