Abstract: The present disclosure describes how a master beacon having a known UUID can be used to capture beacons within its range and superimpose a systematic address scheme on those beacons. The superimposed address scheme can then be used as a proxy for the individual beacons when developing applications that make use of the beacons. A master beacon automatically detects each beacon in a plurality of beacons and, for a set of beacons in the plurality of beacons, automatically changes either the first profile identifier or the second profile identifier for each beacon in the set of beacons. The change is such that the first profile identifier or the second profile identifier is identical for each beacon in the set of beacons and is also associated with the master beacon.
