Hi soundanalogou, thank you for the fast reply!

I’ve set the web servers root directory in the Breakout server and I am accessing the page on the server via localhost:8887.

The connection seems to be okay, the status panel messages looks like in this example after connection to the Arduino and accessing the web page:

My operating system is Windows 7, the browser I’m using is Google Chrome v36. I’ve found a info page where only older browser version where listed as compatible, so I also tried Firefox v17.

Do I have to do something special in the Arduino code? I used exisitng code and just imported and included the AdvancedFirmata libary.
