Hi Brian,
I ran the DistanceTest code with one modification - I commented out the
first line in main, namely
NXTCommand.open();
as there does not seem to be such a method available. Is this a typo or do
you have a new method not present in icommand 0.5?
In any even, running the code without that line gives the results listed
below. As you can see all of the distance measures fail, along with
generating some other error messages.
I also ran the code with the "setVerify" line uncommented, and attach that
output below as well. There was an object about 18 cm from the sonar sensor.
All of this is being done with icommand 0.5, using Eclipse 3.2.1, Java 1.4.2
on a Mac Powerbook, OS X 10.4.6, built-in Bluetooth.
Hope this is helpful,
Myles
