Data is invalid but adds totalDistance

Hello,

I use wialon mobile app to traccar server,

i found this record valid=true but distance is not reasonable.

}

Total distance calculation becomes unreasonable.
how to solve this ?

valid true or false, data from device or traccar do ?

I don't know where you get those JSON logs, but they are not from official version of Traccar.

I modified the display log.

please help

Valid flag is either reported by device, or it's set to "true" if protocol doesn't support this flag.

Hi Anton,

is there any way in traccar to automatically dump tracking data with flag "valid=false" and lat long 0,0 ?
so that i won't appear when i retrieve Reports > Type = Route

based on my opinion, if we succeed to dump data with flag "valid=false"
the distance value won't be like that..

@danny.chiang91, have you tried searching for an answer before asking? It has been discussed countless number of times. Traccar has filtering options that can remove invalid positions and even zero coordinates.
