Wireshark pack dissector or standalone packet formatter for the Flex API

Roger

I've done a bunch of googling and come up empty so it's time to ask the audience.

Has anyone written a Wireshark packet dissector or standalone packet formatter for the Fex API protocol?

I've been using Wireshark to sniff the Flex network but decoding each packet by hand is a very slow and tedious process especially when SmartSDR, a Flex 6000 series radio server, TGXL and PGXL are all involved in my project.

I have a couple of projects in mind that all call for following the frequency the Flex 6000 is on by equipment that's not currently able to be used on an Ethernet network with the Flex API. In one case I just need to disable the transmit interlock while an action is carried out in the transmit / receive path based on a frequency change. In the other case I need to place the PGXL into standby if it's active, set the Flex 6000 to its defined tune power level and transmit an AM carrier to carry out a tuning operation for an antenna.

Thanks in advance for any insights the Flex community can provide me.

73 and good DX,

Here is what I do to find Flex Commands using WireShark.

Run Wireshark, command the Flex Server from Smart SDR.

Filter by IP Source and Destination by right click on IP addresses of interest:

Then apply the IP Filter:

Right Click on a Flex TCP packet, then select Follow TCP Stream:

You can now see the Flex Packets, C are commands, and S are status packets:
