That's what I saw yesterday, but I can't reproduce today. Today, if I
run the server, then GCS, GCS hangs waiting for telemetry.

Do you have link running so you actually have a connection??

Well, it seems not. I assume by "link running" you mean that sw/ground_segment/tmtc/link is running.

Which it is if I use "Execute" but not if I try to launch it from the Tools menu. And the reason for that, it seems, is that Execute adds the -udp option, and Tools does not, with the result that it dies when launched from Tools.

Also, the wiki does not say to run it.

The GCS will always wait until you get messages from some Aircraft, otherwise it has no idea for which aircrafts it should display the strips, flightplan, settings, etc...

Yeah, I get that.

It did. Yesterday, anyway.

Funny you should say that, I've been wondering what that's for. If I
launch it, I just get a blank window.

These tool all have a commandline help option (-h or --help) that show the possible and or required arguments...
For the standalone settings tool you need to specify for which aircraft you want to show the settings (-ac MyAircraftName).
The Python version fails with error "Aircraft ID 11 not found." - the
aircraft ID is 201, btw.

Again, the help option is your friend ;-) -a 201 and you would see the settings for your aircraft.

I was launching it from the Tools menu (I know of no other way). If it can't be launched from there, why have it there?
Beware that the python version is lacking some features compared to the ocaml version (unit conversion, etc..).
If someone would like to bring that up-to-date it would be appreciated (including sane error handling if you don't specify something).

Cheers, Felix
