Abstract
Provided are systems and methods for reversing the conventional roles of central and peripheral devices in a BLE network. Doing so includes implementing an end node (EN) as the sole initiator of a connection between a particular EN and a particular access point (AP). Such implementation includes determining a location of the EN, in which that location is resolved by the EN and defined with respect to association with a reference point (RP) enabled to transmit an ultrasonic waveform serving as the primary basis for the location determination according to detection by the EN of a pseudo-random sequence derived from the MAC ID of the RP.
