I'm trying to set attitude setpoint commands using micrortps. I have it all up and running, meaning the client receives the setpoint commands from the agent. I'm using a publisher through the listener. I can even see the attitude setpoints when I run listener vehicle_attitude_setpoint in the pxh console. But the commands aren't being used by PX4, I can't get into OFFBOARD mode. The only difference between my attitude setpoint commands through RTPS is that the timestamp is 0. I tried to incorporate the timestamp in my publisher cxx file, but it says it is not a member of the vehicle_attitude_setpoint class. Why wasn't timestamp included with the vehicle attitude setpoint command? How can I incorporate the timestamp, and how do I get the correct one inside the rtps agent/listener?
