Sorry for double posting but I am really having an issue getting Pronterface to work on my laptop. in the port box I get this /dev/tty.BLTH. I get this error. Connecting...
Could not connect to /dev/tty.BLTH at baudrate 115200:
Serial error: [Errno 16] could not open port /dev/tty.BLTH: [Errno 16] Resource busy: '/dev/tty.BLTH'
Can someone point me in the right direction to get this working?? What is missing??
Thank you
