Bluetooth HC-06 returns 3 times the same

Using Arduino Networking, Protocols, and Devices
#1

Hi, I am trying to comunicate an arduino UNO with android using the famous HC-06 bluetooth module. Sending things (char,Strings...) from android using a bluetooth terminal app works fine, the problem is that when I use Serial.println to send things to android from arduino it works but I always get what I sent 3 times repeated. I don´t know why, the bluetooth module is with stock configuration, I don't used any AT commands for nothing.

This is the code in arduino:

char INBYTE;
int  LED = 13; // LED on pin 13 

void setup() {
  Serial.begin(9600); 
  pinMode(LED, OUTPUT);
}

void loop() {

  Serial.println("bla bla bla");
  while (!Serial.available());   // stay here so long as COM port is empty   
  INBYTE = Serial.read();        // read next available byte
  if( INBYTE == '0' ) digitalWrite(LED, LOW);  // if it's a 0 (zero) tun LED off
  if( INBYTE == '1' ) digitalWrite(LED, HIGH); // if it's a 1 (one) turn LED on
  delay(50);
}

On android side I tryed several bluetooth terminal app's and all does the same, I always get: bla bla bla bla bla bla bla bla bla

Thanks!

Seems that the problem were the bluetooth terminal applications, they send something like '\n' or anything like this that I was not counting with.
