Abstract: A wireless communication device includes a wireless charging circuit configurable to receive a wireless power signal from a power transmitting unit and to charge the wireless communication device under control of a processing device and in conjunction with a charging session with the power transmitting unit. A wireless interface device operates under control of the processing device to establish a wireless connection with the power transmitting unit via a connection establishment procedure, wherein the wireless connection is separate from the wireless power signal. Control data is exchanged with the power transmitting unit via the wireless connection, wherein the control data is used by the processing device to implement the charging session with the wireless charging circuit. A response is generated to a disruption event of the wireless communication device that includes implementing a restoration procedure for restoring the wireless connection, without implementing the connection establishment procedure.

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.
