Re: cRIO Drops connection after deploy
 

If this is repeatable, please bundle up your project folder and send it to NI support so that it can be investigated. I don't know of a bug or a reproducible set of steps that causes this behavior.

Hi. I'm from team 4125 and we are using also using a Lenovo Thinkpad. The same thing is happening with us. We've tried everything, with no luck. Maybe its the laptop? We're going to try to solve this problem by switching to the computer we used last year. We'll let you know how it goes...

Re: cRIO Drops connection after deploy
 

Despite many reformats and tweaks to our code, we continue to have the same issue as initially described. We will be taking a second cRIO to competition with us in the event we need to switch them.

Note, the issue is only present on one of our cRIOs. The issue does not appear on any of two other cRIO II's formatted with the 2013 LabVIEW firmware.

EDIT - @WeRrobots - I find it hard to believe the issue is stemming form the computer. The error is not reproducible on other cRIOs.

We had issues until we realized the new routers have QOS enabled on them, I would try turning QOS off on the router if you have not already.

Spencer - The symptoms were reproducible when connected directly to the cRIO via an ethernet cable, through the (2012 legal) dlink 1522 Rev A - wired and wireless, as well as through the (2013 legal) dlink 1522 Rev B - wired and wireless.

QOS is enabled on the radio when you use the Radio Setup tool. This is to mimic the bandwidth limits and QOS that is in place on the field. If you are having connection issues that are fixed by disabling QOS, this likely indicates that something you are doing is close to or exceeding the 7 MBps bandwidth limit. You should measure your bandwidth usage (see http://wpilib.screenstepslive.com/s/...ndwidth-usage).

Has anyone been able to send code and instructions to support so that the thread crash can be investigated?

Re: cRIO Drops connection after deploy
 

I'll be able to zip up our code and send it to NI Support tonight.

Re: cRIO Drops connection after deploy
 

Has anyone found out what is causing this problem? We are having the exact same issue.
