I am trying to create a Serial link over Bluetooth from processing to an Arduino. I have USB adapter in my PC and a HC-06 Bluetooth adapter on my Arduino. I have it working with Putty, however when I try to run my processing sketch, the onboard blinking LED on the Arduino Bluetooth adapter stutters slightly but fails to stop blinking (which would indicate a connection). 

Does anyone have any experience with these modules and be able to help?

Thanks
