# WiFi station example (See the README.md file in the upper level 'examples' directory for more information about examples.) ## How to use example ### Configure the project ``` idf.py menuconfig ``` * Set serial port under Serial Flasher Options. * Set WiFi SSID and WiFi Password and Maximum retry under Example Configuration Options. ### Build and Flash Build the project and flash it to the board, then run monitor tool to view serial output: ``` idf.py -p PORT flash monitor ``` (To exit the serial monitor, type ``Ctrl-]``.) See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects. ## Example Output Note that the output, in particular the order of the output, may vary depending on the environment.
