SUBSCRIBE/SUBACK/UNSUBSCRIBE/UNSUBACK are now supported
MQ Telemetry Transport, MQTT is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
I chose phpMQTT in my project publishing message to mosquitto but found it somewhat too old and lack of QoS support. I decided to code my own.
I spended 6 hours watching CSL, Bundesliga, and Barclay’s English Premier League, then brought out this: https://github.com/sskaje/mqtt. Almost the most ugly code I’ve ever written.
Only PUBLISH and it’s related commands are supported until I have enough time to finish it.
It might be a choice to those who are publishing their messages and not subscribing any topic.
