2019-04-25 12:26:48 +0000 | marked best answer | 802.15.4 USBTab frame format Hi all, I have my own 802.15.4 Packet Capturing device (the 'sniffer'), and a python program that collects the frames, and emits a pcap file, which can be analyzed in WireShark. This works fine. Now I want to change to output of the sniffer firmware to a more native Wireshark/PCap format, and just let Wireshark start a USB Tap device. But I have trouble finding out (/finding the specs on) what exactly to send. Hex decoding a working/correct .pcap file gives me: The 'c3000000' is the DLT_IEEE802_15_4_WITHFCS and is only issued once: in the file-header. So - What excactly should I emit from the sniffer-firmware ?
Future: I am aware of the newer/better format of the DLT_IEEE802_15_4_TAP here: https://github.com/jkcko/ieee802.15.4... I just wanted to make a proof-of-concept with the current format first, - if possible. Thx in advance for pointers/suggestions /tpt |
