ESP8266 module STA mode program, the main control chip is MSP430F5438A, the development environment is IAR
MSP430F5438A communicates with ESP8266 through the serial port at a baud rate of 115200 to configure ESP8266.
It mainly completes the connection configuration of indoor WiFi and the configuration of connecting to the remote server. The remote server uses USR-TCP232-Test software
When USR-TCP232-Test software is opened, it will automatically display your computer IP and the port number used, and write it directly into the program.
The IP and port number you need to connect to.
After the configuration is complete, two-way data transmission can be achieved with the remote server in STA mode.
When sending data through the serial port, it is sent in character type ("AT"). After the command is sent, \r\n is sent immediately to indicate carriage return and line feed, completing a line.
Sending operation of the command.
In terms of hardware, when the ESP8266 module is powered on or reset, the instantaneous current is large, and a large capacitor must be connected to the power output to ensure the module is positive.
Work regularly.
Just connect the RST and PD pins of ESP8266 to a high level.
The program comments are not yet complete and will be uploaded later.
