Can't access H20 gimbal from PSDK on M300
Completed
I'm trying to access the laser ranging data from the H20 on an M300. I'm running the PSDK 3.4 sample, option k 'Run camera manager sample' and then option 14 'Get lidar ranging info'. I've tried all three mount positions, as well as other options to access the camera, such as 7 'Shoot single photo', but they always fail during the 'Step 1 Init camera manager module' step. The error I get is as follows:

After I run these commands, it seems like the gimbal resets, as it goes through its positioning test again. I tried using PSDK sample menu option a) 'Gimbal manager sample' on MountPosition No. 1, and that worked, the gimbal moved as expected.
Also, is there any way to turn on the laser rangefinder through the PSDK?
Thanks,
Peter

Please check the settings of USB, For M300 OSDK port, it is need to set this to USB BULK.  -
I changed the setting to USB BULK, and now the sample program is talking to the camera. Unfortunately, I have a new error:
[11.005][downloader]-[Warn]-[DjiCameraManager_GetLaserRangingInfo:2180) Camera a t position 1 don't support getting lidar ranging info.
[11.005][user]-[Error]-[get_laser_ranging_info:74) Get mounted position 1 laser ranging info failed, error code: 0x000000E0.The Zenmuse H20 should be supported, right? I made sure the laser was engaged, so we should be getting range info from it...
