Hi,

I want to send data (x,y and yaw values) over UDP to a system that isn't running ROS (a myRIO or any other micro-controller) I am using a code written in in python (ROSpy) by someone in else that processess the data from the camera. What I have read online is that I can't send data over udp. Can I not create a socket like this?

If not, is it possible to change the code from python to c++ so that I can use UDP?

I'm sorry if the question seem stupid but this is my first experience with python and ROS.

What I have read online is that I can't send data over udp.

Without knowing where you've read this or why that is claimed this is a bit of a dangerous statement, but I would say that is untrue.

There is no magic to rospy, ROS Python programs are just regular programs, so UDP should work.

This is from #q28322.

I understand that they are normal codes, that is why I am confused.

If I post a code would you be able to have a look at it quickly, (the code is only 49 lines)??

That question is specifically about whether the rospy and rosjava client libraries (ie: the Python and Java code that implements the ROS networking and other infrastructure parts) can use UDP.

It is not about whether general use of UDP is possible in rospy.

I must of misunderstood the question. Thanks for clearing it up.

I'm going to assume that sending the data obtained by ROS using UDP is possible.

Thanks!!!!
