Estimotes are Bluetooth 4 beacons. They're not the only Bluetooth 4 beacons but they're the most hyped. You can identify beacons by ID and tell if they're present and how far away they are when they're in range.
Here's how to replace them with something more Free and Open, or how to exploit them: http://makezine.com/2014/01/03/reverse-engineering-the-estimote/ There's SDKs for iOS and Android, System libraries for iOS and Free Software libraries for Android. I think this could be used for all sorts of room-or-building-level locative art... - Rob. _______________________________________________ NetBehaviour mailing list [email protected] http://www.netbehaviour.org/mailman/listinfo/netbehaviour
