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 exchanges of Constant Tone Extensions (CTEs) between the EN and reference points (RPs).
