![]() ![]() If you're on Windows you can just use the tools provided by Nordic on this page, and follow the instructions in the User Guide.Įdit 2018-10: Nordic have released a Mac and Linux app in beta to support their sniffer, so the rest of this post shouldn't be necessary any more. They also provide an application for Windows that communicates with that firmware over USB to get back the sniffing data, and that formats it in a way understandable for Wireshark. Nordic provides firmware for this board that turns it into a sniffer. I use the nRF51 Dongle, which is a dev kit for the nRF51, a BLE + Cortex M0 SoC from Nordic Semi. The software of the chipset inside your computer doesn't support sniffing, so you'll need another chipset whose software you can control. ![]() Sniffing a connection requires support from the baseband layer which is implemented inside the Bluetooth chipset. Checking DNS queries in Wireshark is one of the major tools for studying network behaviors, and Wireshark is by far the leading forum for protocol analysis because of its beginner-friendly and detailed nature.Yes it's possible to use wireshark to analyse BLE packets, but you will need additional hardware. So this is how we can analyze DNS queries in Wireshark and get a detailed knowledge of DNS packet functionalities. Once you have visited a particular resource it will be stored and the next time you want to locate a particular resource, the host will try to find it in the local storage. You can have a look at the below diagram for reference.
