I have the icommand 0.4 installed and I am trying to get it to work.
I am trying to get the sample Melody.java to work. I am running it within Eclipse. It either hangs and does nothing as below under OUTPUT1 or says the port is in use like OUTPUT2. The bluetooth connection is being attempted because the bluetooth icon in the systray changes momentarily when I run it.
I have successfully bluetooth controlled my NXT bot with the bundled Legos software and the Microsoft Robotics Studio, but I prefer Java. Any suggestions to try would be appreciated. If you need any info to help diagnose I would be happy to send it.
If this is not the place for this or there are other places I should also try please email me back and let me know. In fact could someone please send me a reply that this email was received just so I'll know I am sending to a live address.
Thanks for your time.
