Hi, all Is there a way to subscribe newest msg (not srv) at any prefered time? (like client node) I would like to subscribe a specific message by every 5ms. I know it is possible to realize such polling with srv, but Service-Client node allows only srv not msg. How can I realize such polling with msg?
