+  
+  AsyncMQTT_ESP32 is a library for ESP32 boards using WiFi or LwIP W5500 / W6100 / ENC28J60 / LAN8720 Ethernet
+
+  Based on and modified from :
+
+  1) async-mqtt-client (https://github.com/marvinroger/async-mqtt-client)
+  2) AsyncMQTT_Generic (https://github.com/khoih-prog/AsyncMQTT_Generic)
+
