DJI MSDK Waypoint 任务未遵循 waypoints

Question

问题

开始新的 Waypoint Mission 时，无人机最多起飞 2 米，并一直悬停在该位置。另外，发生这种情况时，我只能将无人机无人机调高或调低（最多 2 米）。

预期行为

开始新的 Waypoint 任务时，无人机会完成任务指定的路径。

环境

Phantom 4 Pro 和 Phantom 4 Pro v2（均具有最新固件和飞行安全数据库）
MSDK 4.14.1 和 4.15
Zenfone ZE620KL Android 11（自定义 ROM - DroidOS 5.1）和 Galaxy Tab S3 Android 9（标准 ROM）

测试假设

回避系统启用和禁用
多云和晴天
不同的位置和任务配置
不同的app：我这里用的是Litchi，类似的任务顺利完成

更多信息

我的应用日志和 DJI 日志没有显示任何错误、异常或类似情况。

如有需要，我可以提供飞行记录。

更新 1

我刚刚做了以下测试：

在我的应用程序中开始飞行
打开GO4

从那里，我可以看到我所有的 waypoints 都正确加载，但速度设置为 0。一旦我拉动滑块以提高速度，飞机开始移动并跟随 waypoints不出所料，但我不知道为什么会这样。

Answer 1

如 WaypointMission 对象 所示，autoFlightSpeed 设置为 0。我已通过将 autoFlightSpeed 从 0 更改为第一个航路点中定义的速度来解决此问题，现在一切正常。

根据docs，当autoFlightSpeed设置为0时，“实际速度仅由遥控器操纵杆控制”，这很奇怪，因为它是我一个月的相同代码以前，我可以在不碰操纵杆的情况下飞行。这就解释了为什么我认为我唯一能做的就是“让无人机飞得更高或更低”。可能如果我继续向前推动左操纵杆，飞机就会完成它的路径。剩下的唯一问题是：为什么我一个月前的代码过去不用碰操纵杆就可以工作。
