Because if they are disconnected they are sending the advertising message all the time, and you can recognize and start tracking them. To start sniffing the BT data, first the cores have to be disconnected with the device ( Iphone).The full python code to program the Raspberry pi can be seen in this other article. The Athos suit has a core, which is put inside the T-shirt, and the iPhone, which work as a receptor. These applications only allow you limited access to your data, you have to upload them to the cloud, and the more important, you don’t have access to the raw data. In this case, we want to process the data (maybe in real time, maybe not) and eventually plot them in real time. They are my data, and I should be able to do whatever I want. In this example, I am going to show how I intercept the communication between Athos T-shirt and the smartphone to get the data in a computer, and process and plot them in real-time.Īthos is a fitness T-shirt and shorts which track muscle effort, send them to the iPhone and upload them to the cloud (Why do I want to intercept my data?īecause of that.

I will explain how to sniff and decode your Bluetooth Low Energy Data from your sensors. Intercept Bluetooth communication of smart gadgets (for example fitness devices) is a nice idea to have cheap BT sensor nodes.
