Hi,

I'm trying to program the M300 with Zenmuse H20 with Waypoint V2 so that it takes photos each 3 seconds between two waypoints.
(I'm working on the iOS Mobile SDK version 4.14-trial2).

I've tried the following code and sometimes it works, some other times it doesn't work :
- when it works it takes photos approximately every 3 seconds (from 2 to 4 seconds)
- when it does not work it takes a picture at the start and the two waypoints and nothing in between.



Here is the code I'm using :

        // create a take photo each 3 seconds action

        let ap = DJIWaypointV2Action.init()

        ap.actionId = 9999 // set an unique id

        // create the trigger

        let aptrigger = DJIWaypointV2Trigger.init()

        aptrigger.actionTriggerType = .interval // interval trigger

        // param of the trigger

        let p = DJIWaypointV2IntervalTriggerParam.init()

        p.actionIntervalType = .time // based on time

        p.interval = 3 // each 3 seconds

        p.startIndex = 0 // starting on the first waypoint

        aptrigger.intervalTriggerParam = p // set the param

        ap.trigger = aptrigger // set the trigger

        // create the actuator

        let apactuator = DJIWaypointV2Actuator.init()

        apactuator.actuatorIndex = 0 // index of camera

        apactuator.type = .camera // camera actuator (we want to take pictures)

        let p2 = DJIWaypointV2CameraActuatorParam.init()

        p2.operationType = .takePhoto // take photo as action

        apactuator.cameraActuatorParam = p2 // set the param

        ap.actuator = apactuator // set the actuator

Any idea what can cause this kind of problem?


Some complementary infos that can matter :
- The waypoints path can be only altitude but since I'm using a time interval type it shouldn't matter
- The path between two waypoints takes approx 10s so I should have at least 3 photos
- I picked 3seconds since the limit for JPEG is 2s, I'm supposed to be large
- The Zenmuse H20 is taking pictures with its two lenses.

Thanks for your help!
