Can't push configuration via USB; infinitely loading spinner

[rarenathan]

im trying to save the config to the device, when i do it with usb it just sends indefinitely and nothing happens. when i try via ip i just get failed to fetch

Could you try pushing configuration via USB without any routes set? This should rule out a few issues I am thinking of.

I was running into the same issue. After reading your first reply, I did successfully manage to save the configuration with no routes selected and then again with a single route from a single stop. The moment I add a second route though, I get an error message saying "failed to save configuration / Liveness check timed out" within a few seconds. I also got something along the lines of connection timed out.
I eventually managed to save my configurations by reloading the configuration page every time. It seems to work the first time I hit save after a reload, but in order to make another modification, I have to reload the page again.

Update : my workaround still fails if I try to add more than two routes.

Everything in there works except routes 107 and 25, which are the ones I'm failing to add.

Thanks for sharing that. I suspect you are running into an internal firmware limitation with how big the configuration can be. We try to catch this in the configurator if you reach this limit but sometimes it just fails for reasons I don't yet understand. So I will need to do some additional investigation to understand why it happens and what we can do to fix it.

Thanks for being so responsive and helpful!
I suppose I can settle for two routes for now, if that's what the limit is.

After tinkering around some more adding and removing routes/stops one at a time I can confirm it's something to do with config size, just gotta settle for less routes in the meantime. I would like to suggest the following: since 3 departures fit on the screen at one time perhaps use a page system for large configs? Page 1 3 departures > page 2 3 departures and so on. it could scroll through the pages every x seconds. @tjhorner

I like that idea of alternating pages. I know a few transit agencies who pretty much to that on their own panels. No idea how easy it is to program though.
