/**
 * ABOUT:
 *
 * The bare minimum non-blocking (async) example for working with any networks.
 *
 * The divices used in this example are WIZnet W5500 SPI Ethernet module and ESP32.
 *
 * The complete usage guidelines, please read README.md or visit https://github.com/mobizt/FirebaseClient
 *
 * SYNTAX:
 *
 * 1.------------------------
 *
 * GenericNetwork::GenericNetwork(<net_connect_callback>, <network_status_callback>);
 *
 * <net_connect_callback> - The network connection callback function.
 * <network_status_callback> - The network status callback function.
