Bluetooth queston

Can't see anything obvious but here's my first code for testing Bluetooth.

I used an int and a switch state where you have used a char and an if(state== .....

I can tell you this code works and turns a LED on and off as well as sending a comment back to the android terminal I was using it with. Try it and you will prove your BT connection etc.

#define     GREEN  2                 // lcd GREEN on pin 2
#include    "pins_arduino.h"
int state = 0;

void setup() 
{
    pinMode(GREEN, OUTPUT);
    digitalWrite(GREEN, HIGH);
    Serial.begin(9600); // Default connection rate for my BT module
}

void loop() {
    //if some data is sent, read it and save it in the state variable
    if(Serial.available() > 0)
    {
        state = Serial.read();

        switch (state)
        {
    
            case '0':
                Serial.println("Jeez, a zero! thanks buddy"); 
                digitalWrite(GREEN, LOW);
                break;
        
            case '1': 
                Serial.println("ah, a 1, as in want 1? well OK then, I'll have a pint of guiness");
                digitalWrite(GREEN, HIGH);
            break;

                   
        }
         
   }
}

Good luck, Steve.
