@az311 OK thanks, that Payload Data is definitely from one of our examples (the ASCII codes spell "PKT # ..." ) so your node did join and is sending the data correctly. It's not a problem to see some "Not joined yet..." messages at the beginning - that's how it works - but they should stop once it joined. If you want to see what's happening you can add a message print("Connected!") on line 42 and then and a print("Sent") on 56
