NetBeans robot communication/subnet problems

[Davis.Paul]

Our whole programming team (5 different laptops) are all getting the 255.255.255.255 subnet mask warning even though it is definitely set to 255.0.0.0. I believe all laptops are updated with the latest Netbeans and FRC software, and the cRIO has the 2011 image. We can download code to the cRIO alright from all laptops, but only one laptop so far has been able to see debug output from System.out.println -- the others keep waiting for the cRIO to reboot even though the cRIO reboot has completed and our code is running. Is this warning just something bogus we should just ignore? Any ideas why most of our laptops can't see debug output?

There is something wrong with the warning code. What OS are you using?

Also, if you could post your IP configuration that would be helpful (ipconfig command on windows, ifconfig on mac/linux).


Thanks

The "WARNING" issue:

It turns out that there's a bug in Java 6 on Windows.

When a network interface supports both IPv6 and IPv4, the Java APIs return the IPv6 network prefix length (128) instead of the correct IPv4 subnet mask. And 128 maps to 255.255.255.255.

We'll update the warning code to punt on this case for now.

We also are having the subnet mismatch error. What I am not seeing in this thread is a solution. Any ideas?

[Ben_R_R]

Can you open a command line terminal, run "ipconfig" and post the output?

That would help us narrow down the source of the problem.

[derekwhite]

Blackwood,

Are you just getting the subnet mask warning, and NetBeans claims that your subnet is "255.255.255.255"? If so, that is a bogus warning and can be ignored (as mentioned in post #10).

BTW, that warning has been fixed in the latest release.

If you're getting a different error, please post the text.

Good luck!

[blackwood]

Here is what we are getting. The last line says: Overload me
and it seems to hang at that time.

BTW... I'm just the team coach, I am totally clueless on this, I'm just trying to get some answers for the programmers.

Thanks in advance!

[cRIO] Default IterativeRobot.disabledContinuous() method... Overload me!

[Jose.Pena2737]

I'm having the same problem.

What happens after it gives me the subnet error, It says it's trying to connect to "FTP@ 10.0.0.2" even though our cRIO's IP address is 10.27.37.2.

If I change the cRio's IP to 10.0.0.2, it leaves me hanging on "Overload Me".

I've gone through various updates(I was having this problem two weeks ago, back then, the cRIO image was v25, now it's v27) and nothing has worked.

I would appreciate some help.

I believe this means you haven't set your team number in the preferences of Netbeans. It should be under Tools -> Options -> Miscellaneous ->FRC Configuration. Keep the cRIO's ip at 10.27.37.2.

Are you enabling the robot and getting the same output in Netconsole? Otherwise, I think enabling the robot will fix your problem.

I am the programmer of team 499. I have been using lab view since my freshman year but this year our teacher said That we will be programming in java this year. Mine hangs at "overload me!" as well and I literally have no clue on how to proceed. Please help with detailed and simple instructions.

Sincerely,

Billy team 499

That's probably not hanging. Most methods for robot templates will print out 'overload me' until you overload them. But you usually don't need to overload very many methods. (often just one autonomous and one teleop method) As mentioned below, just stick your drive code into a method like teleopPeriodic (there are probably better ones) and Enable the robot in the right mode.
Definitely take a look at Java samples included with the java plugins.

[Derek012]

What you guys need to do is go into your netbeans options and go to Misc. then from there you will see a tab named FRC config in that tab you need to set your team number to be whatever it is and then it will deploy code to 10.xx.yy.2 instead of 10.0.0.2, also even though the cRio tells you to overload the method the robot should still be able to run.

[Billy_499]

How would I overload it?

[Jose.Pena2737]

Thank you! we have a connection.
