MQTT Protocol on Intel IoT Architecture
summary
MQTT v3.1.1 runs as a lightweight publish/subscribe layer on Intel boards (Joule, Edison, Galileo) and connects to a local Mosquitto broker; a Python service using the Paho MQTT client subscribes to a comments topic, decodes JSON commands, drives a drone (takeoff/move/land) and publishes success acknowledgements to a process_comments topic. QoS 0/1/2 behavior and topic filters are shown, TLS is configurable, and the live demo successfully executes commands and returns ACKs, proving reliable delivery choices on unreliable networks.
