Introduction MQTT (Message Queuing Telemetry Transport) is a lightweight communication protocol based on the publish/subscribe model, specifically designed for low bandwidth, unreliable, or high-latency network environments. It was released by IBM in 1999 and is suitable for connecting remote devices, particularly Internet of Things (IoT) devices. MQTT provides real-time, reliable message transmission services by reducing … Read more
