Problem posting to Ubidots

[rodri16]

Hi Harlequin, I am trying to post some data to Ubidots (ubidots.com) and to another sites like Thingspeak (thingspeak.com) and Plotly (plot.ly). I am using both Arduino wifi shield and RN-XV shield. I made it work with wifi shield but I am having problems with RN-XV. I get this message: close: failed, no CLOS Could you help me? Here is the code... Thank you. Rodrigo
