ESP32 WiFi Library – WiFi.setAutoReconnect

/*
 * Author: Avant Maker
 * Date: February 7, 2025
 * Version: 1.0
 * Description: The example code demostrate how to use setAutoReconnect
 * method to enable automatic reconnection of the ESP32 to a
 * Wi-Fi network. When auto-reconnect is enabled, the ESP32
 * will attempt to reconnect to the previously connected network
 * if the connection is lost.
