Could anybody please provide me with a basic sketch that works with the official GSM/GPRS shield and Xively?
The 1.0.5 IDE contains example programs for pachube, which was replaced by Cosm, and now by Xively. And I have had no luck in updating the old code. And there is no example program on the Xively site either.
PS: I got it working. I will post the code here later today (needs some tidying up).
Ok, here is code that works for me. But I did not implement controlling the LED from Xively.
/*
GSM Xively client
This sketch connects an analog sensor to Xively (http://www.xively.com)
using a Telefonica GSM/GPRS shield.
This example has been updated to use the Xively.com API.
To make it work, create a feed with a datastream, or
change the code below to match your feed.
Circuit:
* Analog sensor attached to analog in 0
* GSM shield attached to an Arduino
* SIM card with a data plan

Would have registered soon anyway, but did it now to say thanks! XD
Thanks for the codes!
Hi,
very interresting but how did you manage to create a free personnal account on Xively ?
Thank you in advance
