Wi-Fi WPS Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example shows how to use WPS enrollee in ESP. The WPS protocol simplifies the process of connecting to a Wi-Fi router.
How to use example
Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>.
Hardware Required
- A development board with ESP32/ESP32-S2/ESP32-C3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
- A USB cable for Power supply and programming
Configure the project
Open the project configuration menu (idf.py menuconfig).
In the Example Configuration menu:
- Use
WPS modeto select the type. - Select
PBC,PINordisable.
In PBC mode, the ESP will wait for the WPS initialization (usually by pressing WPS button on the Wi-Fi router) and then will connect to the router.
In PIN mode, the ESP will enter the WPS mode and you'll see a pin code on the terminal. Enter this pin code in your router and then the ESP will connect to it.
(See your router manual and configuration for WPS compatibility.)
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-].)
See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.

- ESP-IDF Getting Started Guide on ESP32-C3
