The ble-sniffer_win_1.2_user_guide, Figure 4. Wireshark Interface, Packet Bytes window shows a 00 byte at location 0010, which corresponds to the "preamble" of the "Air Interface Packet" defined in Bluetooth Specification Version 4.2[Vol 6, Part B], Section 2. As defined in Section 2.1.1 Preamble, this byte should be either AA or 55 for an Advertising channel packet such as a CONNECT_REQ, which is what is being displayed in Figure 4 of the user guide. I have seen this same 00 byte for the preambles shown in Wireshark output figures for the Adafruit Bluefruit LE Friend nRF51822 Sniffer (which is pre-loaded with the Nordic ble_sniffer firmware) that I have ordered. I am wondering if there is a bug in the sniffer firmware or some limitation that prevents it from capturing or displaying this byte correctly, otherwise how could it be 00 since this doesn't conform to the Bluetooth Specification?
