M300 的Psdk上置接口和下置接口网络问题

M300 无人机在使用下置PSDK接口进行连接时，串口及网络UDP均正常，显示负载IP为192.168.120.2

当同样的程序及转接板，换到顶部上置接口的PSDK接口后，网络通信无法联通，串口正常，且显示负载IP为192.168.140.2，启动程序后的日志为：

psdk register hal uart handler OK
psdk register hal network handler OK
Log file is not existed, need create new.

请帮忙看看是何处的问题谢谢。

通过API：DjiPayloadCamera_GetVideoStreamRemoteAddress 读取一下飞机的IP，然后在设备端ping一下飞机端的IP，上云台飞机端的IP就不是192.168.110.1了。

这个API貌似不是Psdk中的API?在Mobile SDK中读吗？

另外这个IP如果读到了，在PSDK中貌似没看到有地方可配置
