FAQ of Bluetooth Shield

Connecting Bluetooth Shield with Arduino Mega
1 Modify your program:

Code:

#include <SoftwareSerial.h>   //Software Serial Port
#define RxD 10
#define TxD 11

#define DEBUG_ENABLED  1

SoftwareSerial blueToothSerial(RxD,TxD);

void setup()
{
  Serial.begin(38400);
  pinMode(RxD, INPUT);
  pinMode(TxD, OUTPUT);
  setupBlueToothConnection();

}

void loop()
{
  char recvChar;
  while(1){
    if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
      recvChar = blueToothSerial.read();
      Serial.print(recvChar);
    }
    if(Serial.available()){//check if there's any data sent from the local serial terminal, you can add the other applications here
      recvChar  = Serial.read();
      blueToothSerial.print(recvChar);
    }
  }
}

void setupBlueToothConnection()
{
  blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
  blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
  blueToothSerial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as "SeeedBTSlave"
  blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
  blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
  delay(2000); // This delay is required.
  blueToothSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable
  Serial.println("The slave bluetooth is inquirable!");
  delay(2000); // This delay is required.
  blueToothSerial.flush();
}

2 Jumper wires:
Please connect digital 6(7) to digital 10(11) via jumper wire.

Note:Don't forget to turn the PIO[1](switch) to A1 position.
