wlan-pcap-msc

wlan-pcap-to-msc is a python script that I use to generate sequence diagrams posted in this blog. This tool uses tshark to parse an air-trace and then generates a sequence diagram using websequencediagrams. I modify the output of this tool to add more details to the sequence diagram.

The tool can be downloaded from here.
