6.6 Sniffing Advertisement Packets Involving a Privacy Enabled Peripheral

The following are the steps to monitor advertisement packets, scan requests and scan responses to and from a single privacy-enabled device using the Bluetooth Low Energy Sniffer:
  1. Run the Bluetooth Low Energy Sniffer (if not already running).
  2. Input the IRK for the device. In Wireshark, choose IRK as the input key and enter the IRK in big-endian, hexadecimal format with a leading 0x in the input field.
  3. From the device list, select the device or choose “Follow IRK”.
Note: If the Bluetooth Low Energy Sniffer has previously successfully sniffed the pairing procedure, it remembers the IRK needed to identify the device. If not, the user needs to provide the IRK.
