Reverse Engineering a Bluetooth Low Energy Light Bulb is a new guide in the learning system:
This is a fun project that walks through how to reverse engineer a smart light bulb that uses Bluetooth Low Energy (BLE) to change its color. I stumbled on the Smart Bulb Colorific! bulb recently at a local store and was intrigued by its Bluetooth-based control and relatively low price (for a ‘smart’ gadget at least). Because the light bulb uses Bluetooth Low Energy (which is a subset of Bluetooth 4.0) it means any BLE device can in theory control the bulb. But to control the bulb the protocol for communicating with it must be understood, and this guide will show you how to use the Bluefruit LE sniffer and other tools to reverse engineer a Bluetooth Low Energy gadget.
