Apr 02, 2015 · In MQTT over WebSockets, the MQTT message (for example, a CONNECT or PUBLISH packet) is transferred over the network and encapsulated by one or more WebSocket frames. WebSockets are a good transport method for MQTT because they provide bi-directional, ordered, and lossless communication (WebSockets also leverage TCP). Under current HTTPS guidelines, each device should poll for messages every 25 minutes or more. MQTT and AMQP support server push when receiving cloud-to-device messages. They enable immediate pushes of messages from IoT Hub to the device. If delivery latency is a concern, MQTT or AMQP are the best protocols to use.
