What is iBeacon?
iBeacon is an Apple technology designed to help iOS devices to detect their location when approaching or leaving a place equipped with small Bluetooth 4.0 transmitters (beacons).
ubudu platform is compatible with iBeacon, available since the iOS 7 upgrade on iPhone 4S and later versions. That includes ubudu's iOS and Android SDK.
You can use uBeacon devices in iBeacon mode, with the ubudu SDK or using for instance Apple's CoreLocation API.
