Usage

Due to the large current of the GPRS module, a wall adaptor is recommended: http://www.cutedigi.com/product_info.php?products_id=4184

Hardware Installation

Tutorial 1

Jumpers position:

J1: 5100RX to TX1

J2: 5100TX to RX1

Pass through code:

<syntaxhighlight lang="c">

1. include //Used for string manipulations

char incoming_char=0; //Will hold the incoming character from the Serial Port.

void setup()

{

 //Initialize serial ports for communication.

Serial.begin(9600);

Serial1.begin(9600);

Serial.println("Starting SM5100B Communication...");

}

void loop()

{

//If a character comes in from the cellular module...

if(Serial1.available() >0)

{

incoming_char=Serial1.read(); //Get the character from the cellular serial port.

Serial.print(incoming_char); //Print the incoming character to the terminal.

}

//If a character is coming from the terminal to the Arduino...

if(Serial.available() >0)

{

incoming_char=Serial.read(); //Get the character coming from the terminal

Serial1.print(incoming_char); //Send the character to the cellular module.

}

}
