WiFi module baud rate configuring method and system and WiFi module

Abstract

The invention provides a WiFi module baud rate configuring method and system and a WiFi module. The method includes: S1, receiving calibration data sent periodically by an external terminal device; S2, sequentially selecting an unselected baud rate as a current baud rate from at least two baud rates that have been stored in order of priority from high to low; S3, analyzing the received calibrationdata accord to the current baud rate to obtain the analyzed calibration data; S4, judging whether the analyzed calibration data is the same as preset standard calibration data, performing S5 if the data is the same, otherwise, performing S1; S5, configuring the current baud rate as the working baud rate of the WiFi module; S6, sending a matching success instruction to the terminal device so thatthe terminal device stops sending the calibration data periodically. The scheme can reduce the degree of human intervention in the process of baud rate configuration of the WiFi module.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a WiFi module baud rate configuration method, system and WiFi module. Background technique [0002] The WiFi module is a wireless network communication device that belongs to the transmission layer of the Internet of Things. After the traditional hardware device is embedded in the WiFi module, it can directly use the Wi-Fi wireless network to connect to the Internet. It is an important part of the Internet of Things applications such as wireless smart home. In the field of the Internet of Things, serial communication is usually used to realize the data transmission between the WiFi module and the terminal equipment, but different terminal equipment may have different communication rates when performing serial communication, that is, different baud rates, in order to ensure WiFi The module and the terminal device can perform normal serial communication, and the baud rate of...

Problems solved by technology

[0004] For the current method of configuring the baud rate of the WiFi module, each type of terminal device needs to manually modify the baud rate in the software code. Developers need to set the baud rate of the WiFi module according to different terminal devices. The degree of manual intervention in the module baud rate configuration process is relatively high
