MAVGCL doesn't receive or show all messages

[palahmd]

Hello,

Using MAVGCL in combination with the gazebo SITL, it works without any problems when setting the IP and ports in preferences to 127.0.0.1, 14550, 14550. MAVGCL is able to establish a connection and receive all the data.

However, in combination with the physical hardware, MAVGCL receives either nothing at all or just a part of the messages. In my setup, my computer is connected to the RC through a hotspot. The RC itself receives the MAVLink data from the Pixhawk through an air unit and passes it on to my computer. When launching MAVGCL, it doesn't have any connection. When launching QGroundControl first, MAVGCL is able to establish a connection but doesn't receive any data. When enabling the MAVLink forwarding in QGroundControl, it is able to establish a connection (the connection is established and keeps dropping, but data is being transferred), but I don't receive all messages like local position and local acceleration. The IP and ports are set to 127.0.0.1, 14550, 14445.

Is it possible that I'm specifying the ports incorrectly or is it a system error?
