Hi,
i'm new with icommand, I have done a very simple application:
import icommand.nxt.comm.*;
import icommand.nxt.*;
import icommand.navigation.*;
public class Ejemplo {
public static void main(String[] args) {
NXTCommand.open();
TachoNavigator robot = new TachoNavigator(11, 16.9, Motor.B,
Motor.C);
robot.forward();
try{
Thread.sleep(3000);
}
catch(InterruptedException e){}
NXTCommand.close();
}
}
When I execute, first time it works perfectly, but in subsequent
executions, the following exception is thrown:
Exception in thread "main" java.lang.RuntimeException:
gnu.io.NoSuchPortException
at icommand.nxt.comm.NXTCommand.open(Unknown Source)
at pruebas.R2D2.main(R2D2.java:10)
Caused by: gnu.io.NoSuchPortException
at
gnu.io.CommPortIdentifier.getPortIdentifier(CommPortIdentifier.java:218)
at icommand.nxt.comm.NXTCommRXTX.open(Unknown Source)
... 2 more
If I turn off and turn on the NXT brick and I execute again the
application, it works at first time and subsequents fails again.
What could it be the problem?
