Intercept Bluetooth communication of smart gadgets (for example fitness devices) is a nice idea to have cheap BT sensor nodes. I will explain how to sniff and decode your Bluetooth Low Energy Data from your sensors.
Plotting data in real time is a very useful task that could be tough, but using the tool KST, I will show how easy it is. The front end look very professional and clean to present your project. KST is a very powerfull and robust solution for plotting live “streaming” data.
In this tutorial I am going to explain with an example how to stream data from my Arduino to a computer. Later to plot the data on real time I am using KST2.
