Wi-Fi Station Example

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

This example shows how to use the Wi-Fi Station functionality of the Wi-Fi driver of ESP for connecting to an Access Point.

How to use example

Configure the project

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

In the Example Configuration menu:

Set the Wi-Fi configuration.
- Set WiFi SSID.
- Set WiFi Password.

Optional: If you need, change the other options according to your requirements.

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.

Example Output

Note that the output, in particular the order of the output, may vary depending on the environment.

Console output if station connects to AP successfully:
