Hi Gal,
It sounds like you are using Windows. Are you also
using Eclipse? You probably need to turn the NXT off/on after each time you try
something, otherwise it tends to hang. Also, make sure your code isn't still
running when you turn the NXT back on. Once you get things running smoothly
there shouldn't be a need to turn it off/on every time.

Subject: [Lejos-discussion] Question
about icommand 0.4
Hello,
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.
