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 based on position information for multiple reference points (RPs), which may in instances be supplied by the AP. Advantageously, the relative positioning is more particularly based on the received signal strengths (RSS) of beacon advertisement messages broadcast from the RPs, and refined by each of the position information.
