In the era of mobile Internet, all kinds of equipment or home appliances are developing in the direction of intelligence by setting up smart devices that are electrically connected to the control system. Most of the smart devices are based on the Wireless Local Area Network (WLAN) for short, and obtain instructions from mobile communication terminals or network terminals linked in the WLAN to drive the control system to complete related operations, and at the same time transmit data to related servers through WLAN . Connecting smart devices to the wireless network is a step that must be completed. The mobile communication terminal is a common device used to control smart devices. Both the mobile communication terminal and the smart device support WLAN technology, and the data information exchange between the two parties is completed through the wireless access point device called wireless AP device for short. Therefore, in a WLAN environment, there are three typical devices for the interaction between smart devices and mobile communication terminals—mobile communication terminals, smart devices, and wireless access AP devices.

The existing technology uses Bluetooth technology, referred to as Near Field Communication of NFC technology. Communication technology, and static configuration method to complete the configuration of smart devices. Using Bluetooth technology, it is necessary to set up a Bluetooth communication module on the smart device, and use a terminal device with a Bluetooth communication module, a display screen and an input unit to establish Bluetooth wireless communication with the smart device to complete the configuration. The Bluetooth communication module is only used for data configuration. The cost of smart devices has increased dramatically. Using NFC technology, it is necessary to set up an NFC communication module on the smart device, and use a terminal device with an NFC communication module, a display screen, and an input unit to establish "back-to-back" short-distance wireless communication with the smart device to complete the configuration, which will also increase the number of smart devices. The cost, and the penetration rate of terminal equipment with NFC communication capability is not high, and the requirements for communication distance are relatively strict. With the static configuration method, the smart device needs to be electrically connected to the terminal device through a dedicated interface. The configuration process is complicated and requires certain professional knowledge to complete the configuration, which is not easy to implement on home smart devices. Therefore, there are various defects and deficiencies in the prior art, and it is still unable to provide a convenient and easy-to-operate method for the smart device to access the wireless network through the wireless AP device.
