Bluetooth arduino problem!

Hi

Is it posibble to be misprogrammed and has lost the bluetooth funcionality as i send the following code to chip.

int incomingByte = 0; // for incoming serial data
int ledPin = 13;
int count=0;

void setup() {
Serial.begin(115200); // opens serial port, sets data rate to 9600 bps
pinMode(ledPin, OUTPUT);
}

void loop() {
Serial.print(count);
// send data only when you receive data:
if (Serial.available() > 0) {
incomingByte = Serial.read();
if(incomingByte == 0)
digitalWrite(ledPin, LOW);
else if(incomingByte == 1)
digitalWrite(ledPin, HIGH);
}
}

Can you help me please, what to do?

Thank you
