Abstract: A device includes circuitry configured to transmit advertisement data to one or more electronic devices at a first advertisement rate. A presence or absence of the electronic devices is detected within communication range of the device based on a detection signal received from at least one of the one or more electronic devices. A predetermined advertisement rate is modified to correspond to a second advertisement rate based on the presence or absence of the one or more electronic devices.

Abstract: A power transmitting device includes a processor circuit. The processor circuit receives messages, such as advertising messages and/or scan response messages, from power receiving devices. The messages include device specific data that pertains to the corresponding power receiving devices that transmitted the messages. The device specific data includes, for example, data pertaining to the hardware, firmware, charging state, and/or device state of the corresponding power receiving device. The processor circuit selects one of the power receiving devices based in part on the device specific data contained in the messages. The processor circuit initiates a wireless power transfer connection to the selected one of the power receiving devices.
