Can't connect to any com port in WPF sample app

Aug 8, 2014 at 8:24 AM
I am trying to use the WPF sample app to connect to the brick using Bluetooth. I have used 1 to 4 and they all give "Unable to connect error messages. Are these com port of the brick? I am able to use the Lego EV3 software and connect and run projects using Bluetooth without specifying com ports.

I am using Windows 8.1. Are com ports something to setup in Windows? BTW, The bluetooth app under PC Settings says not connected. I did a successful pairing. However the Lego app is able to connect.

So why I am not be able to connect using the WPF app?

I figured it out. I looked at the Bluetooth settings to find out which com port is being used. Also the Lego app needs to be closed. I guess it's blocking other interfaces.
