Wi-Fi SoftAP & Station Example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example demonstrates how to use the ESP Wi-Fi driver to act as both an Access Point and a Station simultaneously using the SoftAP and Station features. With NAPT enabled on the softAP interface and the station interface set as the defaut interface this example can be used as Wifi nat router.

How to use example

Configure the project

Open the project configuration menu (idf.py menuconfig).

In the Example Configuration menu:

• Set the Wi-Fi SoftAP configuration.

  • Set WiFi AP SSID.
  • Set WiFi AP Password.

• Set the Wi-Fi STA configuration.

  • Set WiFi Remote AP SSID.
  • Set WiFi Remote AP Password.

Optional: If necessary, modify the other choices to suit your needs.

Build and Flash

Build the project and flash it to the board, then run the monitor tool to view the serial output:

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)
