The Internet of Things is just around the corner, and somehow or another, all these bits of intelligent dust and juice bag squeezers will have to talk to one another. One of the better ways to get IoT bits talking to each other is MQTT, Message Queuing Telemetry Transport, a protocol designed for small code footprints and limited network bandwidth. It gets a lot of IoT hype, but it’s a great alternative to HTTP for your own small projects, so that’s what we’re talking about during this week’s Hack Chat.
MQTT is a machine-to-machine connectivity protocol, very useful in remote locations, where a small code footprint is required, where bandwidth is at a premium, or for turning a lamp on and off from your phone, while sitting in the same room. It’s ideal for mobile applications, and in the twenty or so years since its creation, MQTT has made inroads into all those ‘smart’ devices around your house.
MQTT is based on a very simple publish and subscribe model with ‘topics’ that allow you to configure where messages should be sent. It is an extremely simple protocol, but with MQTT, you can set up a complete home automation system that opens the garage door, turns on a lamp, or pings a few weather sensors.
For this week’s Hack Chat, we’re going to be discussing MQTT with the entire Hackaday.io community. There are dozens of people who have built MQTT-based projects that frequent the Hack Chat, and hundreds more that want to learn. Want to get in on the ground floor of the Internet of Things? This is the Hack Chat you want to check out. It’s a community pow-wow around connected devices.
Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This week the crew is going to sit down around the campfire around noon, Pacific time, Friday, April 13th (oooh, spooky). Want to know what time this is happening in your neck of the woods? Have a countdown timer!
Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io.
You don’t have to wait until Friday; join whenever you want and you can see what the community is talking about.
