Subject: [ros-users] Question about subscribing a message at any prefered time

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?

Thanks in advance,

Keisuke
