UDP read large datagram error 113

[chine]

Hi,

I work on a project "remote control system of a medical robot " and i need to transform video data. I have choose to use UDP protocol because of its velocity, but I have some problem with the transmission. An error is occured error 113, it come from UDP read " A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the datagram itself".
It is a big problem because I must use it, I know that UDP is not used to send a large datagram but I know also that UDP it used for video transform so I don't know how to solve this problem.

If you have any solutions or other ways to propose me.

Thanks

Hi Chine,

How much byte do you want to send?
Can you please give me copy screen of error message?
Witch version of LabVIEW you use?

Hi Sannat,

I want to sent video by UDP maybe under 65KB in real time and receved it in a remote place. I can send but I can't receve because of a parameter of UDP Read "Byte to read" is 548 bytes max less than UDP write with 1458 bytes so if I send data by UDP write it works but I can't receve them in UDP read. This is the error mess "A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the datagram itself."
So why it is possible to send "large datagram" and impossible to receve.

Thanks

my version of labview is 7.0

Hello Chine,

This error 113 "A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the datagram itself" is known by National Instruments and will be corrected in a forthcoming version of labview.
While waiting, try to "cut" your string data by using the string treatement VIs : "String Length", "String Subset".

Hope this help.
