Experimental solution for position ordering

Anton Tananaev9 months ago

We have a new solution available for ordering positions when device uploads data in the wrong order. The common use case is when device uploads buffered data after network connection was temporary unavailable.

The solution is to have a delay before processing positions. If during the delay, we receive older data, we keep waiting. The result is that all positions are processed in the right order and things like distance calculation should be correct.

If you want to try it, you can download the preview version of the server:

https://www.traccar.org/preview/

You also need to add following lines to the config:

<entry key='server.instantAcknowledgement'>true</entry>
<entry key='server.buffering.threshold'>5000</entry>

where threshold value is the delay in milliseconds.

Please provide feedback.

But if you're new, you might not be the right person to test something experimental.

I have a issue on modern web interface as well as on my custom mobile application too. I cant get any idea to slove this. When I see playback there was a messy lines over lines. How to make it smooth playback of vechiles only with out drawing any line.

I'm testing it with 10 seconds delay.
will report results after testing, distance calculation was causing a big problem for me.
