Using HITL and GAZEBO with own SOLIDWORKS model

Hi all,

I am using my own Solidworks model by the .xacro file in Gazebo. However, I need to use RC to control the aux channel and the joystick cannot control the aux channel ( or maybe I don’t know how to do that). So, I am trying to use HITL.
But when I changed the parameter (hil_mode/serialEnabled), I cannot launch gazebo, it shows “QGC UDP bind failed: Cannot assign requested address, aborting”.

Any suggestions will be welcome!


I found the solution by trial.
