A Flexible Framework for Debugging IoT Wireless Applications

Debugging IoT wireless applications can be a tough task. Different communication protocols may simultaneously operate in the same RF band, giving rise to ambiguities when trying to understand in which order frames are transmitted by the same application or when frames are affected by errors. In this paper we present a flexible framework for capturing all types of communication taking place in the 2.4GHz band, irrespective of the governing standard. As an example, we demonstrate accurate sniffing and time-stamping of Wi-Fi and Bluetooth Low Energy frames.
