JUDP to monitor UDP broadcast

Want to use JUDP to capture this UDP broadcast on port 4992. It occurs about every second. As captured using WireShark:

Yet when I use this JUDP command, I get a timeout. mssg = judp('receive',4992,266,1200) Error using judp (line 166) judp.m--Failed to receive UDP packet; connection timed out. Anyone have an idea why I am not picking up the UDP broadcast using judp?

judp from the File Exchange ??

Yes, JUDP from File Exchange.

Is there a reason why you want to use "judp" over MATLAB's "udp" function? Do you have Instrument Control Toolbox?

I am trying to use the same function and am receiving the same error. I do not have the instrument control toolbox
