The Wi-Fi API provides functions for managing Wi-Fi.

Required Header

#include <wifi.h>

Overview

The Wi-Fi Manager provides functions for managing Wi-Fi. Using the Wi-Fi Manager, you can implement features that allow the users of your application to:

  • Activate / Deactivate the Wi-Fi device
  • Connect to the access point
  • Scans the access points

Related Features

This API is related with the following features:

It is recommended to design feature related codes in your application for reliability.

You can check if a device supports the related features for this API by using System Information, thereby controlling the procedure of your application.

To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.

More details on featuring your application can be found from Feature List.
