Fecha de publicación: 21/07/2022 Fuente: Wipo "IOT" A control method and apparatus for an IoT device, a UWB tag, and a terminal device, relating to the technical field of UWBs. The method comprises: under a working state, listening to a target channel (201); in response to the target channel being idle, sending a data frame on the target channel, so that a terminal device determines, according to the data frame, an IoT device characterized by a UWB tag, and controls the IoT device (202); and in response to the target channel being occupied, listening to the target channel again after a random delay duration (203). The method facilitates reducing power consumption of the UWB tag.
