title: iOS8 - BLE wake up app
body: <p>Is it possible to wake up the iOS app at the exact time (or after some delay) and communicate with peripheral?  My goal is to set an alarm and communicate with peripheral when it's time to ring.
  The only solution that I can guessed is to send a remote (push) notification at that time which will wake up the app and then it can communicate with BLE device. But that way is not acceptable because there are no guarantee that the push will be delivered at the exact time or will be delivered at all.<br>
  So is it possible to awake the app at the exact time which uses CoreBluetooth?</p>
