Wi-Fi

---

The Wi-Fi provides functions for Wi-Fi devices.

Required Header

#include <hal-wifi.h>

Overview

The Wi-Fi devices have various specifications, so it's hard to control them using single code. The Wi-Fi HAL provides common abstraction interfaces to control Wi-Fi devices which are different.

Key functionalities include:

• Initializing and deinitializing the Wi-Fi backend.
• Starting and stopping WiFi interfaces (Station mode, P2P mode, SoftAP mode).
• Retrieving the MAC address of a WiFi interface.
• Controlling the Wi-Fi device through custom commands.

For more information on the Wi-Fi features and the macros, see HAL Wi-Fi programming guides and tutorials.
