dji_camera_manager cannot detect S1 spotlight

[james-avetics]

We want to use PSDK to detect if there is an H30T connected with S1 spotlight on DJI Matrice 400 with dual gimbal mount.

We connected H30T on mount position 1 and S1 on mount position 2. Then, we used

DjiCameraManager_GetCameraType(mountPosition, &cameraType); in

 E_DjiCameraType cameraType;
    E_DjiMountPosition mountPosition;

    returnCode = DjiCameraManager_Init();
    if (returnCode != DJI_ERROR_SYSTEM_MODULE_CODE_SUCCESS) {
        USER_LOG_ERROR("Init camera manager failed, error code: 0x%08X\r\n", returnCode);
    }

    for (int j = 0; j < sizeof(s_cameraMountPosList) / sizeof(s_cameraMountPosList[0]); j++)
    {
        mountPosition = s_cameraMountPosList[j];

        USER_LOG_INFO("--> Step 2: Get camera type and version");
        returnCode = DjiCameraManager_GetCameraType(mountPosition, &cameraType);
        if (returnCode != DJI_ERROR_SYSTEM_MODULE_CODE_SUCCESS) {
            USER_LOG_ERROR("Get mounted position %d camera's type failed, error code: 0x%08X\r\n",
                           mountPosition, returnCode);
        }

        for (int i = 0; i < sizeof(s_cameraTypeStrList) / sizeof(s_cameraTypeStrList[0]); i++) {
            if (s_cameraTypeStrList[i].cameraType == cameraType) {
                USER_LOG_INFO("Mounted position %d camera's type is %s",
                              mountPosition,
                              s_cameraTypeStrList[i].cameraTypeStr);
            }
        }
    }

to detect the connected camera and spotlight. However, it seems like it cannot detect the S1 spotlight as shown in the log below

Questions:

1. How can we detect if the S1 spotlight is connected?
2. What is error code 0x080777BC when trying to get the camera type.

Agent comment from Leon in Zendesk ticket #153721:

Hello,

1. Sorry, there's currently no way to monitor S1 connections in the PSDK.
2. Since the S1 isn't a camera device, it can't use the camera management interface.
