core location - Where to get UUIDs for deployed iBeacon devices? -


if understand correctly, companies mcdonalds , apple have or deploy large numbers of ibeacon ble devices @ stores, each presumably having unique uuid triangulation possible within store. there now, or there be, central place uuids various stores going made available bulk download people want use them in apps?

actually, range of uuids given organisation quite small - 1 or maybe 2. 16 bit minor , major values associated given uuid identify location.

an app can register interest in limited number of uuids (the total number of uuids can registered across apps limited, best organisation use few uuids possible)

once has registered interest in uuid, app notified when device comes range of one. app can display alert user prompting them enter app. if do, app can retrieve major , minor numbers beacon. app can cross reference information against database, possibly via web service, determine location. example major=12 might mean sydney apple store, minor=4 might mean genius bar.

if device in range of several ibeacons can use signal strength estimate range , therefore location, isn't triangulation in true sense.

as whether companies release details of there uuids, major , minor values unknown , vary organisation organisation - data being transmitted in open possible 3rd parties may gather information , make available.
