[Interest] Bluetooth LE: scheduleServiceDetailDiscovery issue

[cagnulein]

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!
