Hi, I have set up SITL on my QGroundControl. I need to provide communication between SITL and Gazebo. However, I encounter some issues while connecting QGroundControl with Gazebo. I can run QGroundControl with SITL, but when I enter “sim_vehicle.py -f gazebo-bluerov2 -L RATBeach - -out=udp:0.0.0.0:14550 - -console” the communication can’t be done wit+h gazebo and also I lose communication between QGroundControl and SITL. I have “link 1 down” on the console as an output.
As far as I figured, the ‘-f’ option in ‘sim.py’ is causing the problem.
The output for SITL:

I couldn’t understand the problem. How can I solve this issue?
ArduSub’ın kendi sitesindeki modellerle deneyince böyle bir bağlantı hatası verdi. Anlamadım da.
