Fuente: Wipo "IOT" The present invention provides a communication mode selection method for a multimode IoT device, said method comprising: receiving and responding to a trigger operation for selecting a communication mode, and causing a multimode IoT device to enter a multimode broadcast state; in the multimode broadcast state, the multimode IoT device sending, to a network device, N network beacons or connection request messages corresponding to the communication mode supported by the multimode IoT device itself, N being an integer greater than or equal to two; receiving a network connection response message from the network device; and triggering, on the basis of the network connection response message, the multimode IoT device to enter a target communication mode corresponding to the network connection response message. The present invention also relates to an IoT device capable of selecting a communication mode and a computer storage medium.
