Abstract
A compatible configuration method for an IoT device, wherein, by adding an energy detection device and a length verification device having a timer to a digital baseband demodulation portion of a Wi-Fi IoT device, when the Wi-Fi IoT device detects an HT-SIG field or VHT-SIG-B field in a header of a configuration information packet from a master device, starting the timer and the energy detection device, so as to judge whether receipt is successful based on whether a recorded time length when channel energy reaches a lower limit conforms to length information in the HT-SIG field or VHT-SIG-B field in the header of a configuration information packet for a higher frequency band mode; and after successful receipt, obtaining transmitted configuration access information sections by computing length differences between received configuration information packets, and then combining the received information sections to obtain configuration access information.
