Bluetooth shield can't write

Products & Technology Shields
#1

I use seeedstudio bluetooth shield and I set it as slave. This is the code:

#include <SoftwareSerial.h>
#define RxD 6
#define TxD 7

SoftwareSerial blueToothSerial(RxD,TxD);

void setup(){
  Serial.begin(9600);
  pinMode(RxD, INPUT);
  pinMode(TxD, OUTPUT);
  blueToothSetup();
}

void blueToothSetup(){
  blueToothSerial.begin(38400);
  blueToothSerial.print("\r\n+STWMOD=0\r\n");
  blueToothSerial.print("\r\n+STNA=BluetoothSlave\r\n");
  blueToothSerial.print("\r\n+STOAUT=1\r\n");
  blueToothSerial.print("\r\n+STAUTO=0\r\n");
  delay(2000);
  blueToothSerial.print("\r\n+INQ=1\r\n");
  Serial.println("BT works!");
  delay(2000);
  blueToothSerial.flush();
}

void loop(){
  blueToothSerial.print("A");
}

I can’t write on bluetooth serial. After upload the sketch, leds of shield blink green/red but after 3 seconds the module doesn’t work and leds don’t blink.
