# 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.

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