Wi-Fi WPS Registrar Example

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

This example shows how to use WPS registrar sotAP mode in ESP. The WPS protocol simplifies the process of connecting to a Wi-Fi softAP from a station.

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/ESP32-S3 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 mode to select the type.
• Select PBC, PIN or disable.

In PBC mode, the ESP will wait for the WPS initialization (usually by pressing WPS button on the Wi-Fi station).

In PIN mode, the ESP will enter the WPS mode and you'll see a pin code on the terminal(If not given through user config). Enter this pin code in your station and then the ESP will connect to it.

(See your station's 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.
