Sending captured data to a named pipe #39

Closed PavelPerkov closed 1 year ago

PavelPerkov commented 5 years ago

Hello I am using Raspberry PI with Microbit board to capture BLE connection. It works without problem, I write data into .pcap file and afterfords read it via Wireshark. But I would like to have opportinity to monitor all packets live. I treid to make pipe, connect it in Wireshark, and send into that pipe .pcap file.

$ mkfifo /tmp/sharkfin $ wireshark -k -i /tmp/sharkfin & $ cat capture.pcap > /tmp/sharkfin &

The same time in this file I write captured data

$ sudo btlejack -c any -x nordic -o capture.pcap

Becouse of command cat, it is not like live, I have to start new session in Wireshark to see new packages every time. I thought, maybe can i send data directly in pipe without any files? somethink like that $ sudo btlejack -c any -x nordic -o /tmp/sharkfin Or do I have other ways? Thanks in advance!
