Can you clarify what stop/start central manager mean? Do you refer to scanning?


2014/1/3 Frederic Visticot <email@hidden>
My iOS7 app tries to scan in background BUT I would like to "track" the scanned device when the app is in background.

Configuration:
- CBCentralManagerScanOptionAllowDuplicatesKey is set to false
- I scan for a dedicated serviceId 

By using a background task + stoping / starting the centralManager I can successfully do the tracking in background (the tracking period is not good compared to active mode + allowDuplicate but it works :)

The pb is when the screen is locked. In that case the scanning process is stopped BUT restart when I unlock the phone...

- Any idea to solve my issue ?
- Is my idea to stop / start the centralManager to discover the same device in background a good solution ? any other solution available ?
