Cant say I have had the chance to try waypoints yet but will test in the next few days. Currently slammed by multiple snowstorms.

Yes, I flew a path of 4 waypoints, in a square with arc mode set. Poi was set on an object outside the square. At each waypoint there is a distinct correction of camera and orientation rather than a nice sinusoidal ease in / ease out.

yikes, so it would just kinda jerk to where the poi was rather than track?

So I managed to pull the Waypoints 2.0 mission video I did yesterday with DJI GO 4 to show what I mean...

This is a simple 8-point Arc-mode mission @ 14km/h, in a circular pattern making clockwise turns, in interpolate mode, and some gimbal pitch adjustments taking place. You'll see very clearly the speed variances and jerky yaw movements during this mission:

All correct, and, so far it is quite frustrating. Even more with the fact that with new smart controller dji enforced new api that prevents litchi from connection to the radio. To take out 3rd party app without giving any adequate replacement is not very helpful. Dunno, when i flew new waypoints routine it felt like it was never tested by dji. Felt raw and unrefined.

See, I was actually considering the SC, but what you just said, that they lock out 3rd-party apps, which actually use their own SDK, is an asinine decision, which just made me say forget it. I was already on the fence with the SC being an Android device, now I’m quite content to sticking with my iOS devices to control my M2P.

That’s the other thing that has me scratching my head... Litchi is built upon DJI’s own SDK, so it’s not like GO 4 doesn’t have access to the same SDK that allows Litchi to do what it does... Why is it so hard for DJI to implement these same functions properly in their own app??

Why is it so hard for DJI to implement these same functions properly in their own app??

Been asking myself same thing over DJI's Assistant and DJI's GO-4.  Like there are two different companies.  One does hardware and one does software.  

My mistake, three.  Other one does Marketing.  Forgetting to inform other two of features required.

Watched Waypoints 2.0 mission video.  All herky jerky.  Seen humans do better.
Something is wrong with Waypoints.

This is an issue with the M2P itself, not Waypoints 2.0.  The M2P performs with the same jerky movements while using Litchi.  Those of us that have been using Litchi for awhile with the M2P were hoping the issue would be corrected by DJI in GO4.  Litchi has been saying it was in DJI’s SDK for quite a while now...

I agree I have abandoned using M2 with litchi , there is a huge difference using litchi with Mavic Pro. Or Air and P4Pro, I believe problem lies between litchi dji and M2 I never thought W2 would be any better than litchi, but it does need some ironing out .

Oracle,

Please refer to my Litchi Waypoint mission video in this link:

I agree that is way smoother, but those are not the results I have gotten using Litchi and the M2P.  All of my other DJI’s are that smooth, with the exception of the Spark while using Litchi.

It's curious you're not getting results like that using Litchi, cause that mission was shot on a M2P, in adverse weather no less, so I'd assume you should be able to obtain similar results since we're talking about the same model drone...
Seeing your footage has given me hope.  Which version are you using?   Currently I am on 2.6.5

I haven't tried Waypoints yet, but did have the issue with Litchi missions. I'd bet cleaning up this issue is on the to do list for DJI now that they have Waypoints 2.0 out there. It's likely both scenarios are related to the same code.

2.6.5? On iOS, latest is 2.6.4, which is what I ran when I filmed that mission...

And here is the mission outline in Litchi Mission Hub:

Look on Positive side.  Even though it was a rough-around-edges flight, your drone didn't do a Fly-Away!

Tried new dji waypoint 2.0 and it was a terrible experience... i agree with all the above posts. (jerky change of directions, drone has to be conected to program missions, slow response on smart controller, etc..)
I have been using Litchi for many years now and really cannot be compared.
Why doenst dji buy litchi allready, and get on with it!

Why doesn't DJI work with Litchi?  It only benefits DJI to make their drones easier to use.

Actually, looking at the Litchi FAQ, it seems they implement the same Gimbal pitch control system that DJI does in Waypoints 2.0, in that it's the Litchi app that directly controls the gimbal, and it's pitch adjustments don't get uploaded to the drone as part of the mission:

From the Litchi FAQ:

It's the heading/yaw/rotation that is jumping abruptly, not the pitch. The pitch appears to work. I'm assuming that the rotation/yaw between waypoints is interpolated on the fly within the aircraft firmware or the SDK inserts interpolated points between two waypoints and currently there seems to be a bug in one or the other. I'm really just guessing here. For one test mission, some paths yaw smoothly and some jump. So it is inconsistent. I also did a test of a two point, zero speed mission with Litchi (cable cam) and it made the same bad moves regardless of the speed I flew back and forth along the path.

I'm going to try to remain positive and, now that the larger feature updates have come out, we'll likely see more refinement work in future updates. It will hopefully be fixed, and resolve both Go4 and Litchi (SDK) at the same time. I look forward to the tweaks to core features that may happen this year.

After having flown a 3DR Solo for several years the Cable Cam of both Litchi and GO4 with the MP2 is very disappointing.

Yet to see any DJI bird with any software offer that degree of smoothness.  The ramping in and out of transitions in pitch and yaw are flawless with the Solo.

This what they should be able to do as far as smoothness.



Interesting that no moderators have commented.

Litchi on P4Pro or even MavAir works just as well as your video. So I’m sure improvements should be possible .

I have looked at many hundreds over the last several years and haven't found one as smooth.; that is why I asked.   Have yet to have anyone point one out either.

It would be nice if DJI would at least fix the MP2 to be as smooth as the earlier models.
