Abstract

The present invention provides a data transmission method and device. The method includes: obtaining information data packets; dividing the preset multicast address into identification code, serial number code and data code; selecting the data bit length of the data code according to the preset requirements, and Determine the data bit length of the identification code and serial number code; split the information data packet according to the data bit length of each code field; encode the split information data packet and store it in the corresponding data bit to obtain multiple multicast Data frames to realize automatic network configuration; each multicast data frame is sent to the network device side respectively. The present invention splits the acquired information data packets through the user end to obtain a plurality of multicast data frames to realize automatic network distribution, and then sends each multicast data frame to the network device end; by making the multicast data frames As an information carrier, it provides an efficient channel for data transmission, and improves the transmission efficiency while ensuring the security of wireless network transmission data.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data transmission method and device. Background technique [0002] The automatic network configuration function needs to be used in the printer to realize data transmission. The existing method generally transmits the Service Set Identifier (Service Set Identifier, SSID) and password of the wireless AP through the UDP broadcast packet, and the network device then passes the received Analyze the UDP broadcast packet, obtain the SSID and password of the wireless AP after analysis, and then automatically connect to the wireless AP. The existing data transmission method can only use the length value of the UDP data packet to transmit the information in order to ensure the use of the UDP broadcast packet to transmit the SSID and password of the wireless AP without purpose, but the transmission efficiency of the data cannot be guaranteed. Contents of the invention [00...
