Hi, I’m trying learn how to use Node-Red and am attempting to send it a UDP packet from my PC and have it display the payload in the debug window with this simple flow (also injecting “blah” as a test):
I’ve tried everything I can think of but no data arrives at the UDP input.
Is there something else I need to do to allow a listening port to open?
I have tried another flow where I am transmitting a UDP packet to my PC and that works.
I have created a udp send using its own ip address in the same flow and it works sending udp to itself. If I do the same sending flow on my other emonPi, nothing is received, so there must be something blocking external incoming udp.
Is there any deeper debugging/logging I can do to figure out why this doesn’t work?
