Connect Arduino via Bluetooth

Hello guys,

I am currently working on a project and I wanted to connect the arduino via Bluetooth. I have researched a lot and now i have paired the arduino with my Mac. However, when I try to choose the serial port of the Bluetooth i get an error saying: processing.app.SerialException: Serial port '/dev/tty.SPIROS-SPP' already in use. Try quiting any programs that may be using it.

Although I get the error the green light of the modem lights (its the one to show it is connected), but I still cannot control the arduino (I have a test code to light an LED when I send 1 in the serial monitor, but nothing happens when I enter 1)

Do you have any ideas??

Thanks in advance!

Some other process on the mac is using that port, this is a mac problem, not an arduino problem.
