Arduino Not Receiving MQTT Subscribed Messages Over ESP8266. I have an MQTT server (Mosquitto) running on a RPi3. I also have a sensor array on my bench that publishes readings to MQTT every 5 seconds. All of this is working great. Tonight, I wired up an ESP8266-01 to an Arduino Mega using one of the Mega's extra hardware serial ports (rx1, tx1). ESP8266 Pub/Sub The code Firstly, we import libraries ESP8266WiFi and PubSubClient. ESP8266WiFi library can connect ESP8266 to the Wi-Fi network, PubSubClient library can enable ESP8266 to connect to MQTT broker for publishing messages and subscribing topics. #include <ESP8266WiFi.h> #include <PubSubClient.h>. ESP8266 MQTT Mesh. Communication. Self-assembling Mesh network built around the MQTT protocol supporting OTA.
