java.lang.RuntimeException: error inside Serial.<init>() COM ports appear busy

in Integration and Hardware • 6 months ago

I dont know what this error means. I have an arduino UNO attached to COM13... the first time I run a processing sketch it works fine and makes a connection but if I stop it and hit play again I get the errors and they only go away with a reeboot.....

This is putting me at a complete halt and I dont even know if its a processing issue, a java issue, or something corrupted in my win8 64bit PC....

It worked fine before but I spent the last 2 days trying to install bluetooth connectivity between arduino and processing....

It never worked and just errored out a lot... something may have gotten messed up on its own but I have no idea how to proceed.... any ideas??????

AVAILABLE SERIAL PORTS:

Stable Library

=========================================

Native lib Version = RXTX-2.1-7

Java lib Version = RXTX-2.1-7

[0] "COM13"

HAVE A LOOK AT THE LIST ABOVE AND SET THE RIGHT SERIAL PORT NUMBER IN THE CODE!

-> Using port 0: COM13
