Implementing the ESP8266 MQTT client using PubsubClient library. Once we have a big picture of the scenario where we want to use our ESP8266, we can start coding the MQTT client. To simplify the client development we will use the PubsubClient library. Therefore, you have to import it into your project. The code is shown below MQTT Client: An MQTT client runs a MQTT library and connects to an MQTT broker over a network. Both publisher and subscriber are MQTT clients. The publisher and subscriber refer that whether the client is publishing messages or subscribing to messages. MQTT Broker: The broker receives all messages, filter the messages, determine who is subscribed to each message, and send the message to these.
