Hi,

After calling rotate from gimbal manager with rotation mode set to DJI_GIMBAL_ROTATION_MODE_SPEED, the gimbal does not rotate and the the function returns error code 224. The PSDK also displays the following message: "Can't support this rotation mode". Gimbal work mode is free mode and other rotation modes work perfectly fine.

PSDK version and build number: V3.2.0-beta.0-build.1569

Drone: MATRICE 300RTK

Camera: Zenmuse H20

Flight controller and camera firmware are the newest.

  PSDK 3.x camera manager(OSDK function) does not support DJI_GIMBAL_ROTATION_MODE_SPEED mode. This mode is used to develop the speed mode when developing a third-party gimbal, and the remote control gimbal dial control will control the third gimbal with speed mode.

  PSDK 3.x claims to have all the functionalities that OSDK 4 provides plus other features and this invalidates this claim. Our application heavily relies on this feature to provide a smooth gimbal control and this impacts our business side of the solution.

  We would be very glad to know if you have any plans to make this available in PSDK 3.x

  The OSDK 4.x version has abandoned the speed control, and only the API compatible with the OSDK 3.x version is retained. We have submitted a requirement assessment to develop a speed control API in PSDK 3.x. Currently, there is a solution that can be considered to continuously control the gimbal to rotate at a minimum angle (such as 0.1, the parameter value can be adjusted according to the speed) through a certain frequency. The gimbal can be rotated smoothly.

  Thank you for your consideration it will defiantly be useful for us to have this API in PSDK 3.x. For now we will try the provided solutions as a temporary patch.

  Regards
