I have the following code:

T_DjiReturnCode event_cb(T_DjiFlightControllerJoystickCtrlAuthorityEventInfo event_info)
{
    std::cout << "curJoystickCtrlAuthority:\n\t" << event_info.curJoystickCtrlAuthority
              << ": " << to_string(event_info.curJoystickCtrlAuthority)
              << "\njoystickCtrlAuthoritySwitchEvent:\n\t"
              << event_info.joystickCtrlAuthoritySwitchEvent << ": "
              << to_string(event_info.joystickCtrlAuthoritySwitchEvent) << std::endl;

    return DJI_ERROR_SYSTEM_MODULE_CODE_SUCCESS;
}

...

autoret = DjiFlightController_RegJoystickCtrlAuthorityEventCallback(&event_cb);
std::cout << "DjiFlightController_RegJoystickCtrlAuthorityEventCallback registered "
"with return code: "
<< to_string(ret) << std::endl;

This all compiles correctly, but the callback is never called. I take control authority and command the drone, when i fly outside the geofence, the drone takes back control, but the callback above is never called.

 

I expect it to be called with:

DJI_FLIGHT_CONTROLLER_NERA_FLIGHT_BOUNDARY_RESET_JOYSTICK_CTRL_AUTH_EVENT 

But it is never called.

I am running this using the PSDK v3.5 on an M350 drone running firmware V7.0

I am connected with serial port only. Should this callback function correctly?

  the DjiFlightController_RegJoystickCtrlAuthorityEventCallback function is currently compatible with the M30 and M3E models. However, it doesn't support the M300 and M350 models at the moment.

  How can i tell if i have passed the Geofence from the PSDK with the M300?

   

  Why does the M350 allow me to call the 

  DjiFlightController_RegJoystickCtrlAuthorityEventCallback

  function? Should it return an error saying not available?

  We have fed back to the PSDK R&D department, suggesting that PSDK code comment or return an error.

  But we also need to be able to get this information somehow. At the moment, if the customer comes within 30m of the geofence the dji drone takes control back, but we are no able to give any warning to the customer. The display mode (DJI_FC_SUBSCRIPTION_TOPIC_STATUS_DISPLAYMODE) still says DJI_FC_SUBSCRIPTION_DISPLAY_MODE_NAVI_SDK_CTRL which is incorrect because we are not able to command the drone.

  How can we from the PSDK v3.5

  1.  tell if he geofence is turned on?

  2. Tell if we have gone past the geofence?

  3. Tell if the drone has taken back control?

  Sorry, PSDK currently does not support getting geofence information.

  Will you be fixing this for PSDK 3.6 release?

  Unfortunately, PSDK currently does not have any plans to support the retrieval of geofence information. About DjiFlightController_RegJoystickCtrlAuthorityEventCallback will add code comments in PSDK 3.6.
