A passive entry, passive start (PEPS) application is described, wherein a number of sensors are configured with wireless communication protocol information for wireless communication between a master device and a BLE hub. The sensors eavesdrop signals from the master device to the BLE hub while not in operative communication with the master device. Eavesdropped signals are processed to determine and calculate position-related information, such as phase and magnitude of the wireless signals received at multiple antennas of the sensors, angle-of-arrival (AoA), and distance or position of the master device relative to the sensors, individually or as a system. Power management techniques for a PEPS system are also described.
