One process publishes information to a topic, other processes can subscribe to that topic. MQTT supports multiple Quality Of Service Levels: bes t effort, at least once, and exactly once. There is a tree of topics, so it is ideal for managing complexity. MQTT is an industry standard, so it runs on every platform imaginable. By the end of the lecture you should know enough to decide if MQTT is right for your projects, and which tools to use. By the end of the tutorial, you will have experience using the APIs and will have built a nice looking chat application.
The class starts with a 15 minute presentation. Then we work with MQTT.
First we will connect to and test our MQTT servers with MQTT Explorer.
And finally we will hook up an html chat widget to the broker. By the end of the class, everyone will have built their own GUI client for the class chat server.
Everyone please install MQTT Explorer.
Here are the Python Class Notes. For the Python tutorial, you should already have a Python 3 development environment installed.
Please install Paho MQTT library.
pip install paho-mqtt
For the GoLang tutorial you should already have a GoLang development environment installed.
go get github.com/eclipse/paho.mqtt.golang
go get github.com/gorilla/websocket
go get golang.org/x/net/proxy
2 - 3 hours is a good length of time for the tutorial.
See you soon!
