 ====== MQTT protocol ======
-MQTT or Message Queue Telemetry Transport is a protocol focused on applications in M2M (Machine-to-Machine Interaction) and IIoT (Industrial Internet of Things) systems. Information transfer to MQTT is implemented according to the Publisher/Subscriber scheme and occurs through an intermediate server (Broker). The data source (Publisher) sends data to the server (Broker), other systems and devices, being Subscribers, read them from there.
