Wireless transmission method and device

Abstract

The invention provides a wireless transmission method. According to the method, information to be transmitted and transmission control information are encoded and transmitted in packet length information of a wireless frame, so that two communication parties can realize one-way information transmission without holding priori knowledge, and the method is characterized in that the transmission control information is contained in a synchronous packet, a serial number packet and a data packet, and the to-be-transmitted information is only contained in the data packet. The transmission data is polled in sequence by taking the transmission sequence as a unit. The to-be-transmitted information is longitudinally coded in the data packet according to a bit sequence, and also comprises data verification information. The invention also provides a transceiving device for wireless transmission. According to the invention, the transmission sequence is spaced and sorted through the synchronization packet and the sequence number packet, and the sequence number field of the data packet is used for sorting in the transmission sequence, so that disorder of the data packet in transmission is avoided.Through multiple rounds of data transceiving, complete data can still be extracted even in an environment with a high packet loss rate, the success rate of data transmission in a weak network environment is increased, and the configuration network access waiting time is further reduced.

Description

technical field [0001] The invention relates to the field of network communication, and mainly relates to a wireless transmission method and device. Background technique [0002] At present, some smart hardware products are mostly Wi-Fi products. These Wi-Fi hardware does not have a human-computer interaction interface, and cannot provide users with an interface for selecting Wi-Fi hotspots to connect to like computers and mobile phones. To make this type of smart To connect the device to the network, the problem of correctly connecting to the router must be solved first. How to safely and reliably transmit the configuration information such as the SSID (Service SetIdentifier, service set identifier) ​​and access password of the wireless network to this type of smart device is the problem to be solved by the present invention. question. [0003] At present, the common practice in the industry: the intelligent hardware is in the mixed mode, and can receive qualified wireless...
