AT+WEBSERVER: Enable/disable Wi-Fi connection configuration via web server

Set Command

Command:

AT+WEBSERVER=<enable>,<server_port>,<connection_timeout>

Response:

OK

Parameters

  • <enable>: Enable or disable web server.

    • 0: Disable the web server and release related resources.

    • 1: Enable web server, which means that you can use WeChat or a browser to configure Wi-Fi connection information.

  • <server_port>: The web server port number.

  • <connection_timeout>: The timeout for the every connection. Unit: second. Range:[21,60].

Notes

  • There are two ways to provide the HTML files needed by the web server. One is to use fatfs file system (non ESP8266 chips), and you need to enable AT FS command at this time. The other one is to use embedded files to storge HTML files (default setting).

  • Please make sure that the max number of open sockets is not less than 12, you may change the number by ./build.py menuconfig > Component config > LWIP > Max bumber of open sockets and compile the project (see Build Your Own ESP-AT Project).

  • The default firmware does not support web server AT commands (see How to understand the differences of each type of module), but you can enable it by ./build.py menuconfig > Component config > AT > AT WEB Server command support and compile the project (see Build Your Own ESP-AT Project).

  • For ESP8266 devices, you may need to turn off some unnecessary options to store the necessary html files.

  • For more examples, please refer to Web Server AT Example.

Example

// Enable the web server with port 80, and the timeout for the every connection is 50 seconds:
AT+WEBSERVER=1,80,50

// Disable the web server, the command should be:
AT+WEBSERVER=0
