nRF Sniffer for Bluetooth LE v4.1.x

Sniffing advertisement packets involving a privacy-enabled Peripheral

Use the nRF Sniffer for Bluetooth® LE to see advertisement packets, scan requests, and scan responses to and from a single privacy-enabled device. If the nRF Sniffer has previously successfully sniffed the pairing procedure, it remembers the IRK needed to resolve the identity of the device. Otherwise, you must provide the IRK.

  1. Run the nRF Sniffer (if not already running).
  2. Enter the IRK for the device. In Wireshark, select IRK as the input key and type the IRK in big-endian, hexadecimal format with a leading 0x into the input field.
  3. Select your device or Follow IRK from the device list.
