GSM library and Seeedstudio gprs 2.0 shield

Hi all.

This question has been touched before on the internet, but I haven’t found any real solution yet.

The thing is that I bought a Seeedstudio GPRS 2.0 shield, and I want to use it as a webserver (a very simple one). I have successfully connected to my APN and the internet as well as doing regular http requests. That’s all good, but I’m during AT commands directly, and I don’t think my initial GPRS connection sequence is robust enough. Therefor I want to use the Arduino GSM library instead. When I read the documentation on that library, it’s clear that it’s developed for the official Arduino GSM shield. As I read it, they don’t use the same chip (which may be the party killer), and they use different pins for serial communication. Changing the serial pins is easy (http://arduino.cc/en/Guide/GSMShieldLeonardoMega - see bottom). So, it all comes down to a question.

Have any of you succeeded in using the GSM library with the Seeedstudio 2.0 GPRS shield and how did you do it?

Best regards

I dont have the Seeedstudio GPRS 2.0, and use a EFCOM GSM/GPRS shield that uses the a different chipset. The GSM lib and examples that come with the Arduino IDE work with some small modifications. Your mileage may vary.

Great. Could you maybe reveal which small modifications you had to do?
