Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for reliable communication between a source device, and two or more sink devices. In one aspect, a sink device closest in proximity to the source device can establish a wireless data transfer with the source device. In another aspect, the sink device having the more favorable radio channel conditions can establish a wireless data transfer with the source device. In some aspects, the sink devices can forward audio data received from the source device over a secondary communication link. The audio data can be forwarded to the other sink device automatically, or upon request from the other sink device. The secondary communication link can be implemented as a magnetic communication link, or as a Bluetooth communication link.

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.
