How to shoot photo at waypoint in flight plan with groundSDK

Can i shoot photo at waypoint in flight plan and how to do it? Thank you.

Hi,

FlightPlanPilotingItf(iOS)/FlightPlanPilotingItf(Android) allows to make the drone execute predefined flight plans.
A Flight Plan file contains MAVLink messages with some modifications for internal purposes.
A documentation of Flight Plan files format should be published in the next GroundSDK release.

The mavlink message MAV_CMD_NAV_TAKEOFF(22) allows to takeoff.
The mavlink message MAV_CMD_NAV_WAYPOINT(16) allows to navigate to waypoint.
The mavlink message MAV_CMD_IMAGE_START_CAPTURE(2000) allows to take pictures.
The mavlink message MAV_CMD_NAV_LAND(22) allows to land.

Following, the content of a Flight Plan file allowing to takeoff; go to a waypoint; take a picture and land.

Hi Maxime,
as far as I understand, message image_start_capture has param "period ": the length of the capture in seconds, it mean that the delay time to take a picture so maybe the point when shoot photo not coincide with waypoint, but i want to shoot a photo when drone arrive at waypoints. So have another answers for this case?
Thank you for you replay and support!

Hi, i am new Anafi Developer.
I have question, how can i observe new photo which being taken at waypoint?

Hi,

The parameter “period” or “Interval” is used to set a time interval between several photos.
The first photo is taken immediately, but take a photo may take time depending to the photo type used.
You can use MAV_CMD_NAV_DELAY(93) to wait the photo taking duration at waypoint before to continuing the Flight Plan.

Hi,

To observe photos taken by flight plan and saved on the drone sdcard, you can get(iOS/Android) the MediaStore(iOs/Android) and observe and browse (iOs/Android) the MediaItem (iOs/Android) list.
The provided observer is notified with the resulting list of media items when it has been first loaded and each time the content changes.
