I am using UDP to POST data to ubidots and it is working fine. If I send two variables successfully I get OK|OK| as a response. What I was wondering is what if the POST was not successful? What should I expect in response? Is this documented somewhere? The only documentation that I have found so far for sending via UDP is http://help.ubidots.com/developer-guides/sendretrieve-data-from-ubidots-over-tcp-or-udp.
