Abstract

In an embodiment, a control device transmits wireless power to an IoT device via a magnetic coupling between at least one antenna of the IoT device and a magnetic field that is generated by the control device. The IoT device powers a short-range wireless communications interface at the IoT device using some or all of the wireless power, which is then used to transfer a firmware update for the IoT device and/or exchange diagnostic information. In another embodiment, a dual-mode wireless power transfer device includes dual-mode wireless power transceiver circuitry that permits operation in a receive-power mode or a transmit-power mode. Wireless power is transmitted by the dual-mode wireless power transfer device in the transmit-power mode, and wireless power is received by the dual-mode wireless power transfer device in the receive-power mode.
