Wireshark capture bluetooth2/13/2023 This post shows using the nRF52840 USB dongle. Nordic provides the free nRF Sniffer for Bluetooth LE software package for turning several of their low-cost boards containing an nRF SoC (System-on-Chip) into BLE sniffers, using the Programmer app in the free nRF Connect for Desktop package. This is a great way to learn how the protocol works or to verify that the devices are communicating properly. That allows you to see the protocol activity, and for unencrypted data, the data contents. Once you’ve captured that data, you can analyze it with tools like Wireshark. The sniffer receives and records the data being broadcast by other nearby BLE devices. For RF (Radio Frequency) wireless communications like Bluetooth Low Energy, the medium is the open air. This is useful for developers and testers doing development, researchers studying system behavior, and students or professionals learning the protocol and device software.Ī sniffer allows you to capture traffic from the communications medium and analyze it. When working with communications devices, it’s helpful to be able to observe the communications traffic. The Nordic Semiconductor nRF52840 Dongle can be used as a BLE sniffer.
