【问题描述】：
我买了一个 DJI N3 飞控。我想在上面使用 Onboard SDK。但是我在激活方面遇到了问题。我已经从该站点获得了 APP ID 和密钥。我已经编辑了 SDK 包中的 sdk.launch 文件和 UserConfig.txt。在运行启动文件时，我得到以下结果。
trishant@Eurus-Holmes:~/catkin_ws/src$ roslaunch dji_sdk sdk.launch

我错过了一些步骤吗？ DJI GO 必须激活吗？
我已将计算机连接到 API 引脚并按照 ROS Onboard 说明进行操作 (https://developer.dji.com/onboard-sdk/documentation/sample-doc/sample-setup.html#ros-onboard-computer)
提前致谢。
