In this very simple example, I will setup a NodeMCU to connect to my MQTT broker and light its LED depending on received messages. This gives a very simple IOT device to test the MQTT protocol.
In this post I’ll explore how to install Mosquitto (MQTT Broker) and test it is working.
First, I will discuss some basic knowledge and expose my problem. Then I’ll talk more in depth about Pebble communication and finally expose the Automate part. So, go straight to the end for the technical part.
I had some hard time installing the BlackBerry Java SDK for (old) OS 7.1 (for Windows or Mac only) on Linux. Here are the main information necessary to setup a working environment in Eclipse (Kepler).
This is it, my first article with a working uBroadcast library in C. Today I discuss a simple example with two programs: the first one is a UDP broadcast sniffer, the second one sends “Hello world!” messages on the network. While furnished archive contains BugOne communication code, I’ll describe it later.
In a coming series of articles, I’ll be presenting a project I’m working on to allow communication between BugOne boards and applications from same or different computers. This project focuses on the development of the uBroadcast library (read micro broadcast). This article is mostly a presentation of the concepts behind.
For my first article I’ll be doing a chameleon Lego Mindstorms LED blink. I will use the color sensor for both the RGB sensor and RGB LED. My goal is to reproduce the color sensed on the RGB LED. The Lego model is really simple, just the color sensor connected to port 1 of the brick.
