Hello, I'm currently working on a university project for which I need to use the HiLo Sagem modlue http://www.libelium.com/squidbee/index.php?title=New_GPRS_module_for_Arduino_(Hilo_-_Sagem) on an Arduino Uno.
I am having some problems with the board, my first problem was with the power supply but I added a 220uf capacitor and now it's working fine.
My current problem is that I am able to send SMS messages using the Arduino as gateway but when I try to send an SMS in standalone mode (using the code from the link above) nothing happens (the jumpers are set to the right position).
Has anyone come across this problem or does anyone know of any means to debugging this problem. I tried using Serial.read() to get the responses from the GPRS module after I send it a command however this returns nothing.
