我通过这个脚本在另一个主机：192.168.10.11 上运行了凉亭 simu：
!/bin/bash px4_dir=$(pwd)
源 $px4_dir/Tools/setup_gazebo.bash $px4_dir $px4_dir/build/posix_sitl_default
source devel/setup.bash export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$px4_dir export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$px4_dir/Tools/sitl_gazebo
roslaunch px4 posix_sitl.launch
和这样的控制台输出：
GAZEBO_PLUGIN_PATH :/home/x-man/Firmware/build/posix_sitl_default/build_gazebo

在 QGroundControl->settings->Comm Links 中，我尝试通过不同的端口创建到此主机（192.168.10.11）的 TCP 链接：
43745 11311 4560
但都失败了，所以问题是：
如何使用 gqcontrol 连接到同一局域网中另一台主机中的凉亭模拟实例？
