My project requires data to be transmitted from a wireless sensor node, via the GPRS network to a datalogging site like Pachube.com
I am using the arduino uno with the seeedstudio sim900 GPRS/GSM module. I have used the sample code found on the wiki. I have got it to sms and make voice calls.
I am having a problem in sending data through to the pachube api.
the code can be found at the bottom of this page:http://www.seeedstudio.com/wiki/GPRS_Shield_V1.0#Hardware_installation
an error is thrown when the shield attempts to make a wireless connection and all the AT commands below that throw errors.
Can someone please help me out here.
