When I'm testing my iBeacon enabled iOS application for different scenarios with iOS 9, I've found that it doesn't discover the iBeacon for a quite a while after I toggle on Bluetooth.
Scenario is as follows,
I kill my application, turn Bluetooth off and then lock the phone. Then I wake the phone via power button and in the lock screen I turn on Bluetooth via the Control Center and wait till the iBeacon monitoring starts.
In the device log I've noticed that the iBeacon monitoring and app ranging has not started even after several attempts.
This scenario fails more often than not in an iPhone 5 which is updated to iOS 9.0.2 and recently I've noticed that this is there in iOS 8.4 device as well.
Any sort of help would be appreciated.
Thanks.
