No Video Feed on M600 drone #384

Open vsars7 opened 4 years ago

vsars7 commented 4 years ago

We're currently using DJIMSDK 4.11.1 and DJIWidget 1.6.2 and getting no video feed display on the Matrice 600 drone.

Same behaviour happened for this sample project with DJIWidget 1.6.2.

The firmware version on the M600 drone is 1.00.01.67

Is this a known issue?

Dear Customer,

Thank you for contacting DJI. Have you set the bandwidth in your project? I try to find a related issue and you can refer to it. https://github.com/dji-sdk/Mobile-SDK-iOS/issues/248 ​ ​ Thanks,

Hi Luce,

Many thanks for your response.

For us, the app doesn't crash but the camera feed is simply blank.

We've seen the same behaviour from the swift sample project: https://github.com/dji-sdk/Mobile-SDK-iOS/tree/master/Sample%20Code/SwiftSampleCode

Can you confirm if the swift sample project is expected to work on the M600 without any changes?

Many thanks

Dear Customer,

Thank you for contacting DJI. The main problem is that need to set the bandwidth for M600. I checked the sample and you can try to modify the code: adapter = VideoPreviewerAdapter.init() to adapter = VideoPreviewerAdapter.init(lightbridge2:true). https://github.com/dji-sdk/Mobile-SDK-iOS/blob/master/Sample%20Code/SwiftSampleCode/DJISDKSwiftDemo/Camera/fpv/CameraFPVViewController.swift#L34

And test it again in the FPV sample.

Thanks,

Thanks Luce,

We tried this with the M600 with a third party camera (Sony A7R), and the suggested fix didn't help.

We'll be trying this again with the M600 and the X3 camera and will report results.

Dear Customer,

Thank you for contacting DJI. Maybe you can check if it can work or not in the DJI GO app first. And contact us again if the trouble still with you.

Thanks,

Re-tested with M600 and the X3 camera and the suggested fix helped! Thanks for your help.

Are there any other flags that need to be turned on to support third party cameras over the EXT port?

Hi Luce,

Many thanks for your help on this issue.

Could you advise if there are any specific flags that need to be switched on to support third party cameras over EXT port?

Thanks once again.
