I'm new to IOT and I'm trying to use my Rpi3 to send temperature readings. I'm using the Copper extension with Chrome and the CoAPthon library. So far, I've figured out how to get the senor data into the CoAP resources file, but when I check the reading with Copper I only get the initial reading. What I want is continuous readings. So that every time I hit the Get button in Copper I get a new reading. Can someone help me with this?
