What is MQTT?
MQTT stands for MQ Telemetry Transport. It defines an exceptionally simple data transmission protocol. It is currently the easiest and most widely used way to send data to the cloud. Data published using the MQTT protocol is in text format. This means that the data structure can be easily converted to JSON (or any other text format) and then published. The MQTT protocol is designed for transmission to devices that do not require high bandwidth. By limiting the transmission speed, the protocol ensures greater reliability.
