Hi,

 Good question. However, we have no API that that is device independant that will provide that. You will have to utilize your platform specific OS calls to provide that. That being said, there is a way. I would create a topic with a deadline

and publish it to myself. However, I would not send any samples. You will then get on_deadline_missed callbacks. Kinnd of hokey, biut it should work.

Hi Irwin

Just to clarify in the thread,

if Data Writer has not published any instance. Deadline will not be triggered.

It is triggered only when a particular instance is not re written  in a time duration.
