nRF Sniffer User Guide v2.2
Page 2
1 Introduction
The nRF Sniffer is a tool for debugging Bluetooth low energy (BLE) applications by detecting packets
between a selected device and the device it is communicating with, even when the link is encrypted. When
developing a BLE product, knowing what happens over-the-air between devices can help you isolate and
solve any potential issues.
By default, the Sniffer lists nearby BLE devices that are advertising, providing the Bluetooth Address and
Address type, complete or shortened name, and RSSI.
