Hi,
I´m using the same shield and I never would by one again, before I had looked for a well designed library.
In the flyer everything sounds well and easy but, all in all it is a fake in my eyes. It takes most of my Uno pins, and is using spi and serial, so normally one has to use a Mega to work with the board.
My target was to build a batterie-guard, sending me a SMS when the temperatur is lower than 3°C and the voltage is lower than 11.5V for example) additionaly when I call the shield with some keywords in a SMS it should send me the gathered data.
It took hours with testing and reading reading and testing, and I´m not ready yet.
The following code will ask for the time and will list some SMS from the SIM card.
I have to work on it - because I cannot understand why this ff... shield is sendig different results when
using
Serial.p r i n t (char(incomingbyte))
instead of
Serial.p r i n t l n (char(incomingbyte));
Because I am not a coder it is really hard for me, to code that.
Maybe you are more successfull. Would be nice to have a hint.
I think it is important to know about the length of buffer size of the shield, but I havent found any hint to that..
after some testst I used 140 to see any results at all.
Additionally I used some delays, because I think the shield needs some time , but its just a rough work, not well formatted and only for testing.
Try it and you will see, maybe it is helpfull for you.
Good luck
