I am doing a project where I have to send an SMS to a given phone number after someone swipes an RFID card on the reader.
Here is the hardware I am using (with Arduino IDE 1.0.5):
Arduino Uno R3 -> http://arduino.cc/en/Main/ArduinoBoardUno
Arduino GSM SHIELD -> http://arduino.cc/en/Main/ArduinoGSMShield
Sparkfun RFID Eval 13.56 Mhz -> https://www.sparkfun.com/products/10406
RFID Module - SM130 Mifare (13.56 MHz) -> https://www.sparkfun.com/products/10126
The problem here is that the GSM
library (included in the IDE) conflicts with the SoftwareSerial
library (used for the RFID). I have read a lot about these and i can't make them work together.
So my approach is now to make them both with the SoftwareSerial
lib. With this i could assign the GSM shield to work with pins 2,3 and RFID with 7,8. Hopefully this will do the trick.
My next step is to send the SMS with AT COMMANDS, but I just can't seem to make this work. Has anyone used AT COMMANDS with the latest arduino GSM Shield? Can anyone provide me a working example code of this? I have been searching everything and still no luck.
Now on the bigger picture, has anyone done anything similar? How did you make it work? Am I using the right approach?
Much help is needed. Sorry for my English, I am Portuguese.
Thank you in advance.
