Abstract
Bluetooth has solidified its status as one of the most prominent and versatile wireless communication technologies alongside Wi-Fi. In spite of its widespread usage, contemporary Bluetooth testing technology still has many unaddressed shortcomings and issues. Hardware limitations, computational complexity, and the lack of standardization are some of these longstanding problems. Furthermore, very few systems possess a proven and reliable capability to test both Wi-Fi and Bluetooth. This paper presents the development of an adaptive Bluetooth test-bed framework that can not only overcome limitations with existing systems but can accommodate other technologies and protocols as well. The work presented in this paper includes: a packet processing and logging utility, a promiscuous packet capture subsystem built around a production test engine, and a complementary subsystem that handles encryption and other security mechanisms.
Highlights
Among the technological advances of the Information Age, modern wireless telecommunication protocol and technologies such as Wi-Fi and Bluetooth have always been considered to be among the most important, if not the most important, innovations of the era [1] [2] [3]
Even though Wi-Fi has traditionally been seen as the predominant wireless technology, Bluetooth has seen an exponential growth in usage in recent years [7] [8] [9]
From the Airpods earphones [11] to specialized applications used for COVID-19 contact tracing [12], Bluetooth technologies truly have a ubiquitous presence in every facet of the economy
Summary
Among the technological advances of the Information Age, modern wireless telecommunication protocol and technologies such as Wi-Fi and Bluetooth have always been considered to be among the most important, if not the most important, innovations of the era [1] [2] [3]. Differences Lacks Inline Mode; Only monitors one BR/EDR or LE channel at a time ; Is designed for certain version and variant of Bluetooth; Is not able to sniff other wireless protocols; Does not provide information about RF environment. Has Inline Mode; Is designed for certain version and variant of Bluetooth; Is not able to sniff other wireless protocols; Some sniffers utilize proprietary packet capture file format; Does not provide information about RF environment. Lacks the ability to sniff other wireless protocols; Most high-end sniffers utilize proprietary software and packet capture file format; Does not provide information about RF environment. The rest of this paper is organized as follows: Section 2 presents background technical details including the basic components of a Bluetooth sniffer, architectural considerations, network protocol, and capture file formats.
