I am curious - what is a speed error?

I got a voice message 'atti mode', but when i looked at the phone there was still sport.
I looked into the logs and it was only a half of second.

speed_error.JPG I am sure compass was calibrated correctly, there was no metal objects or anything what could make interferences. KP index was 2 that day, and i flied around 30 times here before. I used 2.4Ghz OTG.

Please notice that we do not support you use the third party to analyze your flight data.
Please consider the message from your app first, "atti mode" may caused by weak GPS signal.
Any other  error message from your app? More information is needed, so I can help you with the situation. Thanks.

No, there was nothing more in app than voice message. Just half of second 'speed error' in log.

I am curious what exactly this 'speed error' mean. in what conditions that error may appear, what is triggering it. Not only about my case, but overall, what does that mean.

This was in DJI go logs, this 3rd party tool is only a viewer.
I have searched in the internet, found two cases when users got 'speed error', but nothing more.

Does "Please notice that we do not support you use the third party to analyze your flight data. " this mean, you found a way to read the blackbox data?

Please kindly note that we do not support to connect via OTG. Please have a try with WiFi to see whether it remains. If yes, please export the data for analysis, thanks for cooperation.

OTG have no matter there, because this happened on the copter side, not between an app or phone.
So app, cellphone, and connection between them have no matter here.

I prefer to not share my flight logs anywhere, i just asked what 'speed error' means and what conditions may cause it, not why it appeared in my case

Way to go DJI, don't answer his question.  The question pertained to the 'speed error' not how he was viewing the data.  I'd like to know what speed error means?  was it a technical / software issue or just that the sensors couldn't calculate speed when the GPS signal was weak or other.

Had same error once. Asked DJI support  what does it mean?  They answer was: "We suggest to send us back your unit for diagnosis and repair" and no explanations what does it mean...

With these devices max speed itself is not going to affect the machine much. But sudden acceleration/deceleration/maneuvering will certainly put more strain on the batteries.

You need to ease of elevation (forward reverse speed) it can be one of your motors trying to keep up pace with control commands.

Is this only happening when changing speeds from full to stop or reverse?, you should ease your speed by letting stick return to centre not brake by using reverse.

It happened once and it took half a second. I just flied on full speed.  It never happen before, no matter what i did - full forward/reverse/brake/turn.

Day was a bit windy.

However, a something need to trigger that error and i am curious what parameters excession is responsible.
