Hi I've had an early developer edition Due+Ethernet/wiznet shield running connected to xively for a couple of years and decide to switch to thingspeak
Seems like it would be wired Ethernet shield and be transparent to the upper layer.
I tried the example first, and I wonder if anybody can shed some light on the error
