UDP won't read

[Isereau]

I need to read udp data and I know its getting to the card ( I used wireshark to see it) but I need to get it into LabVIEW without using a "packet sniffer".  The UDP read just doesn't seem to work...any suggestions?

Were you trying to add more information, or was that an attempt to "bump" the thread? Please give time for people to respond to your thread. Most of the folks here are volunteering their time, and many (like me) have full-time jobs.

With respect to your question: Please be more explicit. What doesn't work? Are you getting an error? Or, are you getting no data? Same port? Can you post your code, or a screenshot?

UDP read works perfectly, so you are doing something wrong.

Have a look at the shipping example "UDP receiver.vi" for correct code.

If you cannot figure out the problem, attach your VI and we will have a look. 🙂

-Yes I was bumping the thread, I was in a pinch and thought someone might have a quick answer considering most people who use the forum  look at the first page.  I appreciate the help but there is no need to be defensive, we are all here for the same reason.  And if you work in the same industry I am in then you probably realize sometimes you need a problem solved as efficiently as possible.

As for the question intended, the the data is not getting recieved by labview (it is sent fine).   I noticed there is the timeout error but I eliminated that.  It almost seems like a timing issue, although I am an electrical engineer, not a computer engineer, so I don't have a good grasp on networking.

Thanks for the help,

I wasn't being defensive, and it's irrelevant what industry I'm in. I was merely pointing out that you can't always get "immediate" answers on public forums. Sometimes too many people who post on these boards assume there's somebody at the other end ready to pounce on the keyboard when a new question comes in. If you find yourself needing immediate assistance, then your best bet is to contact NI support directly.

With respect to your question: Have you looked at the examples that ship with LabVIEW? If you post your code there more specific help may be provided.

I am reading from port 80, could this be a problem because its the HTTP port?

[smercurio_fc]

HTTP should be using TCP, not UDP. Regardless, any particular reason why you're using 80, when there are so many private ports available?

No, this is no problem. Any port that is not already in use as a server port if free to be used.

It's still not working, Here's a screen shot of my two VI's:
