Arduino library for GSM/3G shield or device with AT commands. It produce very stable and smale code. It also extrem custonable for all sitution with makros.

If you want use ATDev with Arduino IDE or any shield functionalitiy you need set macro flag *_USE_ARDUINO. Now you have this functions:

• powerOn for set a shield on/off power
• initialize use this insteat the ATDev. It is provided for HardwareSerial

Option:

• SIM5218_USE_ARDUINO for a shield functions or with Arduino IDE compile
• SIM5218_USE_SMS for SMS functionable.
• SIM5218_USE_GPS for internal AT GPS handling.
