Hello, I have a Jetson Xavier NX as a companion computer for my drone which uses a pixhawk flight controller. I have the latest firmware beta version on the pixhawk as I’m using ROS2 to communicate with the Jetson thanks to the XRCE-DDS bridge. I have a USB camera connected to my Jetson and a ROS t…

Hi @Toto , time synchronization is automatically managed by the XRCE-DDS bridge. estimated_offset compares the time difference (in microseconds) between PX4 and the clock on the agent side (pay attention that this is the wall clock, not the ROS clock. These two are normally the same as long as the…
