Inadequate SDK for Mini 2

The SDK for Mini 2 is not good. Because quite a few commands don't work. For example:
- Camera Focus Mode does not work
- Camera Video Standard: PAL does not work
- Camera Exposure Compensation does not work

This is really bad, the SKD is not mature.

My equipment:
Mini 2, Galaxy S10, Android 11

- Camera Focus Mode does not work
- Camera Video Standard: PAL does not work

AFAIK, the Mini 2 does not support these features (I do not see them anywhere in DJI Fly), so not why you are expecting the SDK to have them.

- Camera Exposure Compensation does not work

This appears to be working for me. Do you have specific steps to reproduce this error, or a screen recording?

Hi Jim, unfortunately I don't know how to do screen recording. Try to find out.
Here ist the flight:

Can you share your mission plan so I can make some suggestions?

This mission plan doesn't set the exposure compensation. I guess I am confused. Do you still have a question or an issue?

Sorry, Jim, you don't have to be confused. The plan I postet is a new plan, that works. The old plan I don't have anymore. Step by step I understand Dronelink better and better. Thanks for your support! Greetings from Germany.

How about the ISO and the shutter speed?

I tried to make a map but the Image was washed/blurry. So eher the drone was to fast (15m/s) or the camera settings wrong. So i tried to Set the iso to 800 and shutter speed to 1/1000 but i got a message something like 'Not in this mode'.
Will Do a Screenshot tomorrow.
And i'll try to copy Toms camera settings.

Or is it not possible to change camera settings for mapping?

It is all possible, you just need to put those commands into your mission before the map.

I tried with just the Shutter Speed Setting

Tried to add "Stop Capure" and "Camera mode: photo" ... still getting the following error:

I'll try some other settings:

a) changing to photomode from videomode -> mission accomplished but Shutter not

b) camera exposure lock enable -> mission accomplished but Shutter not

...oohh, maybe I got it:

After trying the setting Camera Exposure Mode set from Auto -> Shutter Priority the following Camera Shutter Speed set to1/800s -> mission accomplished

But whats the Camera Exposure Mode!?

It looks like maybe you didn’t set the camera into manual exposure mode before issuing that command? The key to using commands, is you have to issue every singe command, in order, that you would do in the UI. You would be forced to change the exposure mode before the UI gave you the option to set the shutter speed, so the same applies to commands.

Camera Exposure Mode -> manual solved that issue!

Whats that command behind the following symbol? It locks the ISO and Shutter if highlighted. But with Camera Exposure Mode -> manual that symbol doesn't change?

Whats the differance between Camera Exposure Mode Manual and Camera Exposure Lock enable?

Auto exposure lock (enabled / disabled).

Thank you!

The Exposure Modes are new for me. Could'nt find that function in the DJI App.

I searched the web but just found an explanation for cameras:
1. Manual mode: this mode puts you in full control of the three settings on your camera that control the exposure (commonly known as the exposure triangle). ISO, aperture and shutter speed. In manual you will be making all of those choices.
2. Aperture priority: (A on Nikon, Av on Canon) this mode has you in control of two of the three exposure controls: ISO and aperture. The camera will select an appropriate shutter speed to give you a correct exposure.
3. Shutter priority: (S on Nikon, Tv on Canon) this mode once again puts you in control of two of the three exposure settings, this time it is ISO and shutter speed. The camera will select the aperture for a correct exposure.
- I choose Aperture Mode when I want to control depth of field (DoF) as my top priority. Such as to create shallow DoF for a portrait, people photos, or any time I want a blurred background (choose a large aperture like f2.8 or f1.8). That also applies if I want a larger DoF as well such as for a landscape photo, group portraits, or shots where I want maximum detail and sharpness (choose a smaller aperture like f11 or smaller)
- I choose Shutter Mode when my top priority is controlling motion, either freezing or blurry it. So freezing for subjects like sports or action and I will choose a faster shutter speed such as 1/500th or faster depending on the subject. Subjects like flowing water, waterfalls, or panning a moving subject I will select a slower shutter speed like 1/15th for panning and 2-5 seconds for flowing water. (for more on this topic read my article Using Shutter Speed to Freeze or Blur Motion)
- I switch to Manual Mode in a few specific instances: doing a portrait where the subject is not moving; night photography; pretty much any time I’m using a tripod; doing HDR bracketed exposures (even though my camera does 7 on AEB I still use Manual when on tripod); when using studio lighting; certain times when using a speedlight (such as working in a dark room and I want to maintain some ambient light levels)

Does that explanation fits to Dronelink, Jim?

e.g. in Aperture Mode changing Shutter Speed doesn't make sense or ist going to fail?
