WiFi module network distribution method based on UDP broadcast length coding

Abstract

The invention discloses a WiFi (Wireless Fidelity) module network distribution method based on UDP (User Datagram Protocol) broadcast length coding. A mobile phone sends a preamble packet to a WiFi module; the WiFi module receives the leading packet sent by the mobile phone, locks the channel of the wireless router and waits for receiving a configuration packet; the mobile phone side sends a configuration packet containing the WiFi password and the SSID length; after the WiFi module receives the configuration packet, an analysis strategy for the data packet is clarified; the mobile phone side sends a data packet containing the WiFi password and the SSID length; and the WiFi module carries out analysis to obtain a WiFi password and an SSID, the WiFi password and the SSID are used for connecting the locked wireless router, the WiFi module sends a configuration success instruction to the wireless router after the connection is successful, the WiFi module confirms that the network distribution of the WiFi module is successful, and the configuration process is ended. According to the method, the WiFi module based on UDP broadcast length coding is utilized, the mobile phone and the WiFi equipment are enabled to interact through a small amount of data, and the WiFi equipment is connected to the wireless router, so that the data transmission quantity and the protocol complexity in the network distribution process are reduced, and the network distribution speed and the success rate are improved.

Description

technical field [0001] The invention relates to the field of network design, in particular to a method for network distribution of WiFi modules based on UDP broadcast length coding. Background technique [0002] Due to the popularity of home WiFi, smart home devices generally choose to use WiFi modules to connect to home networks. At present, there are three mainstream smart network distribution methods on the market: 1. SmartConfig mode: make the WiFi module inside the smart device in the mixed mode, and the mobile phone will fill the SSID and password of the wireless router in the MAC layer UDP packet according to a certain format. For the unencrypted packet header, use the broadcast method to send these encoded packets to the home wireless router multiple times. The WiFi module obtains the data packet by scanning the channel and capturing the packet, and completes the network after the analysis is successful; 2. WPS one Key distribution network: By operating the WPS key ...
