I also figured this out, eventually.
The upload is fast, but no transmissions. How do you get the output of the module to see I things are being published as expected?
I know I can debug etc, but to test "live" I have to unplug the module, then replace it, and the tiny headers don't look like they will take to many cycles before they bend/break (plus I can hardly see them anyway...). I must be old, no! they are just small.
