Hello everyone,I’m working on a ROV using Pixhawk 2.4.8 as my flight controller and Raspberry Pi 4B with Ubuntu 22.04 LTS and ROS2 Humble as my companion computer.I’m having trouble running this command:
ros2 run mavros mavros_node apm.launch fcu_url:=/dev/ttyAMA0:921600.
I got no errors,but it kept warning me:
