In the usc file a json_out_port is mentioned. How is the out port used?\r\n\r\nI have problem using the json interface. I create a node and directly after I ask for the id of the node but the node is not created yet. So how do I synchronize that? What is the feedback for a create request? The documentation have code doing sleep(1) but that is not acceptable since then it will take to long time to do operations like updating the GeoPose."}}
