MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT Sparkplug is an interoperability protocol for smart manufacturing and industrial automation use cases. Sparkplug provides a consistent way for equipment manufacturers and software providers to share contextual data to accelerate the digital transformation of existing operations. It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in a wide variety of industries, such as automotive, manufacturing, telecommunications, oil and gas, etc. Description Currently, MQTT is only available in Linux based controllers, which includes the X5, XL4, EXL6, EXLW, XL7, EXL10, XL+ – and all RCCs EXCEPT the RCC6510. Bi-directional Communications MQTT allows for messaging between device to cloud and cloud to device. This makes for easy broadcasting messages to groups of things. Reliable Message Delivery Reliability of message delivery is important for many IoT use cases. This is why MQTT has 3 defined quality of service levels: 0 – at most once, 1- at least once, 2 – exactly once Support for Unreliable Networks Many IoT devices connect over unreliable cellular networks. MQTT’s support for persistent sessions reduces the time to reconnect the client with the broker.
