Bug report

In the latest version of Copter (4.5.0) the FCU communication via UDP port is not working, if trying to communicate via Mavlink (MAVROS) Issue details A ROS2 node, initialized in python as following

mavros_node = Node(
        package='mavros',
        executable= 'mavros_node',
        parameters=[
            {'fcu_url': 'udp://127.0.0.1:14551@14555'},
            {'gcs_url': ''},
            {'target_system_id': 1},
            {'target_component_id': 1},
            {'fcu_protocol': 'v2.0'},
            apm_pluginlists_file,
            apm_config_file,
        ],

        namespace='/drone1',
        output='screen',
        respawn=True,
)

I had to downgrade to version 4.3.0. Version Copter-4.5.0

How do you launch SITL ? It is working as we are using it on CI, so that mostly some misconfiguration on your side

[oselin]

The SITL is launched by using the following bash script https://github.com/oselin/drone-pose-estimation/blob/main/src/iq_sim/scripts/simulation.sh

while the environment was set up by using https://github.com/oselin/drone-pose-estimation/blob/main/install.sh

I basically followed the the following tutorials https://www.youtube.com/watch?v=r15Tc6e2K7Y&list=PLy9nLDKxDN6-34W07yZECzp_Yc2WmWIYH&index=1

By simply downgrading to ArduCopter v4.3.0 or v4.3.1 it works. I fixed the issue in this way

Hey Are using MAVROS with MAVPROXY simulteneously? If so, how? Can I connect with my physical quadcopter and mavproxy and mavros using the same telemetry radio?
