Hi.
It’s a little difficult to determine what might be going wrong with your code. I don’t see anything obviously wrong, but from your problem description, it would seem the post to xively is having some trouble.
If you could attach or show a before and after sample and the output from xively, we might be able to determine what’s going on. For example, if you could show the serial output without the calls to xively, the with the calls to xively, and then show what xively claims it received, that might be helpful.
Also, if you could print the values in “feed” just before you call the client, it might be helpful in figuring out what xively is doing.
Thanks!
