Using CoreBluetooth with iBeacons

Question

I\'ve been doing quite a bit of research on iBeacons and CoreBluetooth on iOS devices. Your posts and research have been great. I\'ve learned quite a bit. Unfortunately, i\'m

As mentioned in the blog post, you cannot get any of the iBeacon identifiers out of the CoreBluetooth APIs because iOS does not provide access to the raw advertising data that encapsulates these identifiers.

You may be able to do correlations. If only one BluetoothLE device is visible, and you just saw an iBeacon using CoreLocation APIs, you can continue to track the beacon with CoreBluetooth, reading the RSSI as you suggest.

The trouble comes when multiple BluetoothLE devices are visible. Without access to the iBeacon identifiers in CoreBluetooth, how will you know which device you are seeing in CoreBluetooth lines up with which of the iBeacons you see with CoreLocation? Unfortunately, I do not think there is any way to match them up.
