Erroneous Speed Issue When the Device is Parked

jose juan2 months ago

Hello,

I am facing a problem with my device's configuration. When it is parked, it sends erroneous speed data in each received frame.

   <entry key='report.trip.minimalTripDuration'>360</entry>
    <entry key='report.trip.minimalTripDistance'>1000</entry>
    <entry key='report.trip.minimalParkingDuration'>30</entry>

    <entry key='report.trip.minimalNoDataDuration'>30</entry>
    <entry key='report.trip.greedyParking'>false</entry>

    <entry key='distance.enable'>true</entry>

    <entry key='filter.enable'>true</entry>
    <entry key='filter.zero'>true</entry>
    <entry key='filter.skipLimit'>300</entry>
    <entry key='filter.accuracy'>29</entry>
    <entry key='filter.duplicate'>true</entry>
    <entry key='filter.maxSpeed'>230</entry>

    <entry key='coordinates.filter'>true</entry> 
    <entry key='coordinates.minError'>30</entry>
    

    <entry key='event.motion.speedThreshold'>4.5</entry>

I have tried several solutions, but I cannot filter out this error. Temporarily, I used the configuration 

<entry key='filter.distance'>29</entry>

which helps, but it also disables the parked device notification.

Could you please guide me on what I might be doing wrong or how I could solve this issue? I appreciate your help in advance.

Best regards,

You have a skip limit, so filtering won't work all the time. That explains why you still have some speed values. GPS almost never returns exact zero as speed.
