A Bluetooth low-energy capture and analysis tool using software-defined radio
Christopher David Kilgour · Summit (Simon Fraser University) · 2013
Wireless protocol analysis is a useful tool for researchers, engineers, and network security professionals.Exhaustive BTLE sniffing -the full capture and analysis of Bluetooth Low-Energy radio transmissions -has been out of reach for individuals to apply to research, engineering, and security analysis tasks.Discovering and following an arbitrary Bluetooth frequency-hopping pattern with a cheap narrow-band receiver is a complex undertaking with little chance of success.Further, the high-end test equipment capable of wide-band processing is prohibitively expensive to small organizations and individuals.This project includes an analysis of the problem, and a description of a wide-band Bluetooth sniffing implementation with open-source software and softwaredefined radio (SDR) techniques.A number of real-world signal captures are collected and processed, and the recovered Bluetooth data is presented.The resulting implementation is also published under an open-source license.
