Arduino Bluetooth Connections

I am trying to send a string from my arduino to the serial monitor. I am using the sparkfun bluesmirf chip with an arduino UNO.

my code is really simple:

void setup() {
Serial.begin(115200); // begin serial communication at 115200 baud rate
void loop() {
Serial.println("hello world"); // write hello world
delay(1000); // delay one second

When I open the monitor I recieve gibberish. When I connect to the arduino with a usb cable everything works fine.

Can anyone please put me in the right direction?
