No notice of loss of signal?

I was flying a grid map and all was going well, then my battery indicator went from over 40% to 0% (indicated).

The Mavic Air landed on its own, and Airdata claims it landed in place with over 40%. So, it seems like it landed from extended loss signal and not a dead battery, but I got no notice of signal issues. What is the normal behavior for Pix4DMapper on iOS for when signal is lost? Does it hover and then land or return home?

Hi,

Thank you for this feedback. Pix4Dcapture can not override the fail-safe behavior of the drone and then the drone should behave up to what is set in DJI GO 4.
Also, if flying with the iOS version of Pix4Dcapture, did you use the Safe mode to fly?

When you say “it landed on its own”, do you mean that the drone did not come back to its homepoint?

Best,

It landed far away on the flight path. It did not return to home.

I don’t know what you mean by “safe mode.” What is that?

The Go4 app has loss of signal set to return to home:

Hi,

Pix4Dcapture is not displaying any information about the signal while flying. The behavior the drone should adapt in case of signal loss is defined in DJI GO 4 as it is shown in the screenshot you sent and this behavior can not be override by Pix4Dcapture.
Also Pix4Dcapture is only displaying the battery information of the drone. In your case it seems like a failure occurred which lead the drone to land immediately.
Could you reproduce what you experienced? In some cases, if it can’t be reproduced, it might comes the drone and we suggest to be sure on how to interrupt a mission if an unexpected behavior occurs.

I would suggest you go through the basic checks and troubleshooting steps as it will solve most of the issues that can be encountered by users if properly followed.

The Safe mode, using the iOS version of Pix4Dcapture is a specific mode to trigger images. It can lead to a RTH of the drone with its battery still being quite high due to a DJI limitation but it does not seem to be your case.
