seeed bluetooth shield working, android to arduino to console and vice versa. would like to turn a pin on or off. how to turn on arduino pin from android? send a 0 or 1 from android to arduino, make do something... also someone in a another thread mentioned the while loops are wrong, too many brackets or some such. This code needs some commenting to explain whats going on in the void loop or while loop and how we can make arduino do stuff. Nonetheless it works for testing. im using galaxy note,app is called bluetooth spp, uno, seeed BT shield( bluetooth library and examples on seeed wiki page).
#/*
BluetoothShield Demo Code Slave.pde. This sketch could be used with
Master.pde to establish connection between two Arduino. It can also
be used for one slave bluetooth connected by the device(PC/Smart Phone)
with bluetooth function.

This code needs some commenting to explain whats going on in the void loop or while loop and how we can make arduino do stuff.

Why don't you do that, then?

Posting the code correctly would be a good idea, too. That is done by pressing the icon with the # on it, not by typing a #.

i have been using this code and it works good so far NOTE:i put my BT Tx pin on 5 and Rx on 7 and instead of NewSoftSerial i used SoftwareSerial

here is my edited version of turning an led on pin 13 on and off sending "1" and "0".

#include <SoftwareSerial.h>   //Software Serial Port
#define RxD 5
#define TxD 7
 
#define DEBUG_ENABLED  1

int incomingByte;
 
SoftwareSerial blueToothSerial(RxD,TxD);
 
void setup() 
{ 
  Serial.begin(9600);
  pinMode(RxD, INPUT);
  pinMode(TxD, OUTPUT);
  pinMode(13,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);
    }
    if (recvChar == '1') {
        digitalWrite(13,HIGH);
    }
    if (recvChar == '0') {
        digitalWrite(13, LOW);
    }
  }
} 
 
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();
