An apparatus for a power transmit unit, PTU, capable of inductively, magnetically or wirelessly transferring power to one or more power receive units, PRUs, the apparatus comprising: circuitry ; a detect component (622-1) for execution by the circuitry configured to detect a first PRU based on use of a transmitted short beacon, wherein the short beacon is used to detect an impedance or charging load associated with the first PRU; a beacon component (622-3) for execution by the circuitry configured to transmit a long beacon to cause the first PRU to energize a low energy wireless communication interface; a receive component (622-4) for execution by the circuitry configured to receive a first advertisement, ADV, packet from the first PRU including fields indicating support for forward signaling and no signature field, the beacon component configured to modulate a remaining portion of the same long beacon during which the first ADV packet is received responsive to the receive component receiving the first ADV packet, the remaining portion of the long beacon modulated to include a modulated signature, the receive component configured to receive a second ADV packet from the first PRU; a connection component (622-5) for execution by the circuitry configured to send a connection request to establish a first communication link with the first PRU through the low energy wireless communication interface when the second ADV packet includes a signature that matches the modulated signature included in the remaining portion of the long beacon; and a transfer component (622-6) for execution by the circuitry configured to cause transfer of power to the first PRU while maintaining the first communication link. circuitry ; a detect component (622-1) for execution by the circuitry configured to detect a first PRU based on use of a transmitted short beacon, wherein the short beacon is used to detect an impedance or charging load associated with the first PRU; a beacon component (622-3) for execution by the circuitry configured to transmit a long beacon to cause the first PRU to energize a low energy wireless communication interface; a receive component (622-4) for execution by the circuitry configured to receive a first advertisement, ADV, packet from the first PRU including fields indicating support for forward signaling and no signature field, the beacon component configured to modulate a remaining portion of the same long beacon during which the first ADV packet is received responsive to the receive component receiving the first ADV packet, the remaining portion of the long beacon modulated to include a modulated signature, the receive component configured to receive a second ADV packet from the first PRU; a connection component (622-5) for execution by the circuitry configured to send a connection request to establish a first communication link with the first PRU through the low energy wireless communication interface when the second ADV packet includes a signature that matches the modulated signature included in the remaining portion of the long beacon; and a transfer component (622-6) for execution by the circuitry configured to cause transfer of power to the first PRU while maintaining the first communication link. <EOS>
