I am trying to run the multi-vehicle simulation and I can see the active mavros node for each UAV. But when I open Qground control it does not detect the UAVs.

here are my commands:-


cd Firmware_clone

git submodule update --init --recursive

make posix_sitl_default

make posix_sitl_default sitl_gazebo


In the above last command gives error. So I skip that one and source environment before launch the file for multi-vehicle simulation. I can see the simulation. after following commands:-  

source Tools/setup_gazebo.bash $(pwd) $(pwd)/build/posix_sitl_default 
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$(pwd):$(pwd)/Tools/sitl_gazebo

roslaunch px4 multi_uav_mavros_sitl.launch
