(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:
