I have connected the module to arduino uno rev3.
I have downloaded the libraries above and try to send sms using the example inside the library.

But NO sms is received.
I’m using external adapter 12V/1.2A to power the arduino

In the monitor i get :

GSM Shield testing.

status=READY

SMS sent OK

Any idea what is my problem ?

Hi,

I’d like to use your library with TinyGPS library.
But when I declare un TinyGPS gps; variable, there is a problem, there is nothing on the serial monitor.

Do you know why ?

Thanks

In the zip file
https://code.google.com/p/gsm-shield-arduino/downloads/list
there is a doc:

How to switch between Arduino Mega and Arduino Uno?

1)
Open GSM.h and comment-decomment the appropriate lines like below
e.g. for Arduino Mega
//#define UNO
#define MEGA

2)
If you use Arduino Uno comment the line in HWSerial.h or decomment if
you are using Arduino Mega
e.g. for Arduino Mega
#define MEGA

3)
Save and compile

Hi Boris, referring to Luigi’s question on using the shield on a Mega board: should I change, for example, the line #define _GSM_RXPIN_ 5 to #define _GSM_RXPIN_ 52 in the GSM.cpp file and then connect the D5 on the GSM Shield to the D52 of the Arduino Mega Board? P.S.: I got the old version of the GSM Shield

Hi Boris, do you mean that on a Mega board I could change in the GSM.cpp file this line #define _GSM_RXPIN_ 5 to, for example, #define _GSM_RXPIN_ 52 and connect the D5 of the GSM shield (I got the old one) to the D52 of my Mega board?

Thanks

Sebastian

Hi. I would like to use this shield to send data via GPRS to a server. Is there any example where I can see this? If not, have you finished the tutorial that you mentioned in your last post that you were going to prepare?
Thank you very much for your help.

@benz and Sara
in the library there are some example.
We are working on a tutorial to simplify the learning.
