Hello,

Did the code example I provided for Arduino work with your Processing code?  
You should see output similar to what I have.

The delay() was related to this:

I kept the spirit of the original example intact and left it as a “Simple Write” program. My edit of “SimpleWrite” example so it only sends data once: /\*\* \* Simple Write. \* \* Check if the mouse is over a rectangle and writes the status …

I edited my last post on this.
