[ros-users] re-subscription

[Klaus Petersen]

Hello,

I have a very basic problem: First, I establish a connection between a
publisher node and a subscriber node. At this point I can receive
messages from the publisher with the subscriber node. But when I
re-start my publisher node (quit and run again) the subscriber does not
automatically resubscribe to the message. I have to restart the
subscriber as well to be able to receive again. Is this the normal
behavior with ros or am I doing something wrong? I have quite a big
robot control program tied to one of the nodes, so restarting along the
way (the initialization of the robot takes ages) is very troublesome.

Cheers,
Klaus
