Hi,
I am facing a weird issue. I am running HITL with custom simulator. I am using pixhawk 6x with px4version 1.15.4 and QGC version 4.3. I find that the MAV_2_CONFIG parameter is set to ethernet by default and the corresponding network (MAV_2_UDP_PRT) and remote port (MAV_2_REMOTE_PRT) are set to 14550 which is same as the QGCs UDP port.
From custom simulator I am also sending the data received from px4 to QGC at UDP port 14550. I see that when I run HITL the vehicle crashes immediately as shown in QGC. But the hardware is not connected via any ethernet port. It is only connected via the USB port used for serial communication with the simulator.
When I set the remote and the network port to something else say 14555, I see that the vehicle flies successfully in QGC. My doubt is how is this possible that though there is no ethernet connection the default parameter values of MAV_2_x params are affecting the communication?
Can anyone please help me on this?
Thanks,
Sayan
