Conexion Arduino uno+gprs

Buen día! soy nuevo con esto del arduino y he estado jugando con el con los demos y haciendo programas para poder entender un poco mas, ahora estoy tratando de escribir los datos del arduino uno a una DB que esta en la red, aun no he logrado poder comunicar y hacer la transmision, si alguno de ud. me puede ayudar, se los agradecere, adjunto un ejemplo con el cual he intentado trabajar con el, pero aun no he podido.

web original http://www.seeedstudio.com/wiki/GPRS_Shield_V1.0#A_Simple_Source_Code_Examples

/*Note: this code is a demo for how to using gprs shield to send sms message, dial a voice call and
send a http request to the website, upload data to pachube.com by TCP connection,

The microcontrollers Digital Pin 7 and hence allow unhindered
communication with GPRS Shield using SoftSerial Library.
IDE: Arduino 1.0 or later
Replace the following items in the code:
1.Phone number, don’t forget add the country code
2.Replace the Access Point Name
3. Replace the Pachube API Key with your personal ones assigned
to your account at cosm.com

Cualquier comentario sera bienvenido, gracias.

A ver, quizás en lugar de poner el código de ejemplo deberías poner el que estas utilizando.
En cuanto a lo de escribir a una Base de Datos es algo que ya se ha comentado varías veces por aquí. En lugar de intentar escribir directamente sobre la DB, intenta hacerlo mediante un PHP o JS.
Lo mas comodo es mediante GET.
Creas un String

String Destino= "www.direccion.dominio/archivo.php?sensor1=" + toString(Variable1) + "&sensor2=" + toString(Variable1);

y haces una llamada GET normal con esta dirección. Si deseas añadirle seguridad yo pido autentificación de esta forma evito errores y ataques simples a la base de datos
