What language(s)? Do the topics match? Is it all on one machine? What do the log files say? Do they work if you start them outside the launch file?<br><br><div class="gmail_quote">On Fri, Mar 5, 2010 at 11:21 AM, Robbie Plankenhorn <span dir="ltr"><<a href="mailto:rplankenhorn@gmail.com">rplankenhorn@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I am trying to get a publisher/subscriber connection working within my own ros pkg and I am having issues. I am able to get the talker/listener tutorial working but what I am doing is slightly different.<br>
<br>I have an ros program that sets up a TCP socket and waits for a connection. When the user sends the appropriate command on that socket, I want it to publish a message and that message is redirected to the other program. Right now, everything starts using a launch file and when it starts, the publisher shows that there are 0 subscribers and the subscriber shows that there are 0 publishers.<br>
<br>Are there any special timing conditions that I need to take into account? Is there anything else that I should look at?<br><br>Thanks,<br><font color="#888888">Robbie<br>
