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 following parameters under Example Configuration Options:

Set WiFi SSID and WiFi Password and Maximal retry under Example Configuration Options.
Set Static IP address of your device static IP.
Set Static netmask address of your device static netmask address.
Set Static gateway address of your device static gateway address.
Set Choose DNS server with Set manual value as DNS server or Use gateway address as DNS server to configure your DNS server.
Choose Set manual value as DNS server to configure manual DNS server with Main DNS server address and Backup DNS server address.
Set Enable DNS resolve test to resolve your host which input in Domain name to resolve.

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.
