Hi everybody, i'm here today to ask you about a problem than I meet with my BT shield. I've got an AT MEGA 2560. When I upload the code, I've only got the green light blinking 2 times per cycle instead the green and the red. I know that means the connection doesn't work but being a perfect newbie on arduino, I don't know if it's the code or the circuit. I receive "The slave bluetooth is inquirable!" from the Serial monitor displays as well. Looking for a request, I still have not found one. I've already seen : but vainly..

The code than I use is here :

#include <SoftwareSerial.h>   //Software Serial Port
//This is for the Arduino/seeeduino Mega.
//Not all pins on the Mega and Mega 2560 support change interrupts,
//so only the following can be used for RX: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
#define RxD 10
#define TxD 7
#define DEBUG_ENABLED  1
SoftwareSerial blueToothSerial(RxD,TxD);
void setup()
  pinMode(RxD, INPUT);
  pinMode(TxD, OUTPUT);
void loop()
  char recvChar;
    if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
      recvChar =;
    if(Serial.available()){//check if there's any data sent from the local serial terminal, you can add the other applications here
      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.

Thanks !
