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 coordinate location of the EN based on position information for multiple reference points (RPs) and a time of flight (TOF) of an ultrasonic waveform transmitted by each of the RPs.
