Sending a Dat table via UDP

catweasel · October 8, 2025, 2:06pm

Hi, I am trying to make a patch to send rplidar data via UDP to another pc (running vvvv) I have got data, I’ve culled it somewhat for out of region values, but now I’m struggling to work out how to send the udp. It needs to be converted into bytes I understand, I found this snippet that in a python region can print to the viewer op(‘delete2’).numpyArray().tobytes() (delete2 being my culled data chop). I have tried to use this expression in the UDP node, but that doesn’t seem to do anything. Any suggestions as to ways to go about this?

Does no one use UDP? The one thread I found about UDP had a dead link, and there is little documentation, unless I need to search for something different?

In vvvv I have used UDP to send skeletons and point clouds or depth images from multiple mini pc’s to a server, amongst other many other things, it is (or should be) a fairly basic thing to do shouldn’t it?
