What with certification case - we have to setup somehow NOA values
requested from testTool?

Do you suggest NOA interval should be same as Beacon interval?

Yes, this is case for using larger interval.
eg.
interval = 2s
duration = 1s

Regarding resolution, I only add some functionality to API that
currently exists - duration is also in ms.

Anyway I think this could be usefull for test + some certification case.
