DF Robot Module + Arduino = HELP???

Hi Does anyone know how to connect the DF Robot Bluetooth module up to the arduino and get it to communicate with the software?

I used this tutorial yerobot .com/download/mannual/DF-Bluetooth%20Manual.pdf

I managed to get the light flashing on the module and seems to be able to pair fine but however when i run the serial monitor and send a letter say 'H' which should turn a light on i get a java error

I checked the wirling and i have the RXD going to the RX(pin 0 ) on the board and TXD to TX(pin 1) and the rest wired up but again still no luck anyone have any thoughts

~edit this is also the code i have on the arduino

int ledpin = 13;
char val;
void setup() {

pinMode(ledpin, OUTPUT); // pin 48 (on-board LED) as OUTPUT
Serial.begin(9600); // start serial communication at 9600bps

}

void loop() {

if( Serial.available() ) // if data is available to read
{
val = Serial.read(); // read it and store it in 'val'
}
if( val == 'H' ) // if 'H' was received
{
digitalWrite(ledpin, HIGH); // turn ON the LED
} else {
digitalWrite(ledpin, LOW); // otherwise turn it OFF
}
delay(100); // wait 100ms for next reading

}

hey, ive just bought one and cannot get it to work with the Arduino IDE but it seems to work fine with max/msp and terminal once the code has been uploaded via usb!

The Baud Rate should 115200, instead of 9600. Try different baud rate.
