I call RemoteRetrievalTaskSample Demo to trigger searh record video. When I call retrieval video, I can’t see the request command to device from wireshark package immediately. And I can see the command needing waiting some minutes. So I want to know what trigger mechanism is.
In the Management Client on the device you have a Remote Retrieval tab, if you have some settings here the remote retrieval might be delayed. A guess could be that these mechanisms could play a role even if nothing is configured. You might see the first retrieval task start immediately or at least within a few seconds, while two tasks very close in time you might experience a delay on the second task.
