ESP32 HTTPClient Library – connected

/*
 * Author: Avant Maker
 * Date: February 21, 2025
 * Version: 1.0
 * Description: This example code demonstrates how to 
 * use the ESP32 HTTPClient Library's connected method to 
 * monitor the connection state before and after making 
 * a GET request. Ensure your ESP32 is connected to a 
 * Wi-Fi network before running this code.
