The latest version 03.00.01.02 for H20T can not achieve the payload_download function

[Watson-OU-221]

Hi,

After I have updated the latest version for H20T, the payload_download function becomes invalid, which means the photos could not be downloaded from the H20T card to the manifold successfully. However, it could succeed for the last version of H20T. I can achieve other functions (such as flight control and get the main camera stream ...) except the payload download functions.

The problem is listed below:

[3144462.991]ERRORLOG/1 @ startReqFileList, L431: Current state cannot support to do downloading ... [3144462.991]ERRORLOG/1 @ printErrorCodeMsg, L938: >>>>Error module : Camera [3144462.991]ERRORLOG/1 @ printErrorCodeMsg, L939: >>>>Error message : Camera is busy or the command is not supported in the Camera's current state [3144462.991]ERRORLOG/1 @ printErrorCodeMsg, L940: >>>>Error solution : Check current camera state is if appropriate fot the CMD

Could you tell me about what the Error solution means? How to check the camera state?

My development environment:

Matrix 300; Manifold 2-C, ubuntu 16.04; H20T; OSDK-ROS 4.1.0; OSDK 4.1.0;

Dear developer ,

Thank you for contacting DJI.

Sorry for the inconvenience. Currently, we have found that the photos in the H20 SD card downloaded failed after upgrading the latest firmware. And test it works only when the number of photos is less than 3, and we have submitted it to the relevant engineer. If you need this function, you can temporarily roll back the firmware version to use.

Thank you for your understanding and support, hope you have a nice day.

Best Regards, DJI SDK Support Team

Thank you for your reply! I hope the new firmware version will support the download function soon.
