I have two "shield" Arduino : GPRS (of Seedstudio) and GPS (Parallax). I'd like to use these two shield in the same time on an Arduino Uno. That I want to do : If I send a SMS with "gps" as content, the Arduino send me a SMS with the Latitude and Longitude.
Separately GPS and GPRS works. But when I want to use both together, it doesn't work. :~ I try wih many libraries : TinyGPS, gsm-shield-studio, goGPRS and also without libraries.
Do you think Arduino Uno as enough RAM for this project ?
If yes, do you know what is the problem ?
