That's good to know, thank you. It's the sort of thing that could easily trip me up. I haven't had that error yet, but I will add the line you suggest for the test program.
Thinking big picture though, if I just add it as is, then my program will block forever at that point if it never connects to the Mesh? Since this is running on the Argon which is the gateway, it should not block forever there unless something else is seriously wrong, right?
