ESP32 WiFi Library – WiFi.softAPSSID

Home / References / ESP32 Library / WiFi API / AP

Description

The softAPSSID method is used to get the SSID (network name) of the Wi-Fi Access Point (AP) created by the ESP32. This method is part of the ESP32 WiFi Library and is useful for retrieving the SSID of the AP in softAP mode.

Syntax and Usage

The softAPSSID method can be used to retrieve the SSID of the softAP. It does not require any arguments.

String ssid = WiFi.softAPSSID();

This usage retrieves the SSID of the current softAP configuration.

Argument(s)

This method does not require any arguments.

Return Value

The softAPSSID method returns the SSID of the softAP as a String.

Example Codes

This example demonstrates how to use the ESP32’s softAPSSID() method to retrieve the SSID (network name) of the device when operating in SoftAP (Access Point) mode. The method returns the currently configured SSID, which is useful for verification and debugging purposes.

To use this code, upload it to your ESP32 board. It will create an access point named “AvantMaker-ESP32-AP” with password “12345678”, then retrieve and print the SSID to the Serial Monitor at 115200 baud. This confirms the AP is broadcasting with the correct network name
