"payloads_download_sample" sample application giving timeout on DJI Matric 300 RTK

[akamilkhan]

We are trying to run "payloads_download_sample" sample application on DJI Matric 300 RTK. When we try to get filelist or filedata, we are getting a timeout.

[1372534.780]ERRORLOG/1 @ fileListMonitorTask, L154: downloadMonitorTask timeout!! device type : 1 index: 0
[1372534.780]STATUS/1 @ SendAbortPack, L957: SendAbortPack
[1372534.781]STATUS/1 @ fileListReqCB, L34: ##[Download main camera file list] : ret = 255 
[1372534.781]STATUS/1 @ fileListMonitorTask, L164: Finish req filelist task cause of timeout, reset downloadState to be DOWNLOAD_IDLE

The odd thing is, it starts working after we access the album from the handheld joystick. It keeps on working after that until we reboot the drone.

Any idea what might be going wrong?

Here are the complete logs from the application:

Dear developer ,

Thank you for contacting DJI.

The odd thing is, it starts working after we access the album from the handheld joystick. It keeps on working after that until we reboot the drone. Any idea what might be going wrong? -->OSDK and remote control (APP) cannot access the album at the same time.It is recommended that you verify this function of the OSDK without operating the APP. If the APP has access, please exit the album for a period of time (about 30s) and then access through the OSDK.

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

Best Regards, DJI SDK Support Team

We have had the same experience. The SD card functionality seems to be still in beta state pretty unreliable. Not even putting the album mode takes it out of the state where it constantly timeouts.

Hi @dji-dev,

If we don't use remote control (APP), OSDK gives the error that is shown in logs shared in issue descriptions.

For the logs shared in description, remote control (APP) was turned off.

Thanks, Kamil

Dear developer ,

Thank you for contacting DJI.

1. Make sure that the dual A usb connection is normal and the USB communication works.
2. If it still doesn't work, you can try to format the SD card first. and then verify this function after taking a new picture.

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

Hi DJI,

Thank you for the response.

We tried again the things that you mentioned but nothing changed. We are still getting the timeout.
