Overview
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.
Security Enabled
MQTT makes it easy to encrypt messages using TLS and authenticate clients using modern authentication protocols, such as OAuth.
