Second, the client of the Internet of Things extends and extends between any item and item. For information exchange and communication. Managing wireless sensors is one of the most important functions of IoT gateways. The commonly used concept is "pair code". The meaning and function of so-called "code" is that IoT gateways need to know which wireless sensors belong to this gateway management. The networked gateway will discard messages sent by wireless sensors that are not within the scope of the gateway management. At the same time, the IoT gateway will assign an identification code to each sensor. The identification code can be used internally by the gateway or at the gateway. Used when communicating on the IoT platform. At present, the wireless sensor pairing method generally sends a specific pair of code messages when the wireless sensor is in the code state, and after receiving the pair of code messages, the Internet of Things gateway can implement the code matching function of the wireless sensor. However, the existing wireless sensors are various and do not all have the function of transmitting the code-to-code message. Therefore, the sensor that does not have the function of transmitting the code cannot be coded, and the IoT gateway cannot have the function of sending the code.
