For many Bluetooth developers sniffing the link between a Bluetooth Host CPU and a Bluetooth Host Controller also known as HCl sniffing is much more useful than air sniffing HCl sniffing provides direct visibility into the commands being sent to a Bluetooth chip and the responses to those commands With air sniffing a software engineer working on the host side of a Bluetooth chip has to infer and often guess at what their software is doing With HCl sniffing the software engineer can see exactly what is going on HCl sniffing often results in faster and easier debugging than air sniffing 158 ComProbe High Speed UART User Manual Appendicies ComProbe software s Virtual sniffing feature is a simple and easy way to perform HCl sniffing Virtual sniffing is not limited to just HCl sniffing but it is the most common use and this white paper will focus on the HCl sniffing application of Virtual sniffing It is also important to understand that ComProbe software is a multi mode product ComProbe software does support traditional air sniffing It also supports serial HCI sniffing for the H4 HCI UART H5 3 wire UART and BCSP BlueCore Serial Protocol protocols USB HCI H2 sniffing SDIO sniffing and Virtual sniffing So with ComProbe software nothing is sacrificed the product is simply more functional than other Bluetooth protocol analyzers A 1 3 Bluetooth Sniffing History Frontline has a strong appreciation for the importance o
