问题详情

我尝试用mavros连接到DropixV2单元，我使用了一个安装了Ros kinetic的jetson卡，jetson卡和dropix都通过一个开关连接
现在，通过使用 TCP Link 指定 IP 地址 (192.168.1.130) 和端口 (4003) ，我设法在我安装在 jetson 上的 apmplanner 或 qgroundcontrol 上获取 FCU 数据。 （我认为 DropixV2 / Jetson TX2 可以正常工作并且配置正确）但我无法通过 mavros 连接到 fcu。

我使用的udp地址是：
我使用 apm.launch 文件启动 Mavros 节点，其中
< arg name = " fcu_url " default ="udp: //: 14550 @ 192.168.1.130@5760" />
< arg 名称 = " gcs_url " 默认 = " " />
其中192.168.1.9是pixracer的IP地址->它不起作用，我尝试使用“udp：//： [email protected] .1.130 @ 4003”，它也不起作用
