A3 + LB2 with Z30 requires some initialise settings to make the video works.

1. You need to set the bandwidth allocation through LightBridgeLink class, setBandwidthAllocationForLBVideoInputPort depends on your settings. Link：https://developer.dji.com/api-reference/android-api/Components/LBAirLink/DJILBAirLink.html

2. Please try the Github link below and see if you can see the video stream view. Try https://github.com/dji-sdk/Mobile-SDK-Android first and then https://github.com/dji-sdk/Mobile-UXSDK-Android.

Sorry for late answers. Another problems raised --- how to use zoom with FPVWidgets, Z30 and Mobile SDK. Also reset camera position.

I don't think FPVWidget implements zoom features for Z30, this is a very old camera, you have to implement this feature by yourself. setOpticalZoomFocalLength: https://developer.dji.com/api-reference/android-api/Components/Camera/DJICamera.html#djicamera_camerasettings_setopticalzoomfocallength_inline

reset: https://developer.dji.com/api-reference/android-api/Components/Gimbal/DJIGimbal.html#djigimbal_resetgimbalwithaxisandresetdirection_inline

Hello DJI-William 1) I have succesfully implemented Zoom in and Zoom out on C1 and C2 buttons 2) Gimbal reset does not work. I implemented the methode call on right dial push (callback works fine) but I get DJIError: "Not supported(255)"

My implementation: private void resetGimbal() { if(myGimbal != null) { myGimbal.reset(Axis.YAW, ResetDirection.UP_OR_DOWN, new CommonCallbacks.CompletionCallback() { @Override public void onResult(DJIError djiError) { Log.i("gimbalError", djiError.toString()); } }); } }

[DJI-William]

What is your Z30 firmware, it must be later than v01.01.03.00. Also, if you select Axis.YAW, according to the documentation, you can only set ResetDirection.CENTER. You can check the doc.
