Anti Jammer

vol8 years ago

Hi,

First of all I enjoy using this product!
Nowadays cars are stolen with GPS\GSM Jammers.
Sadly but GPS will not be tracked at all... :(
As the result may I propose next feature:
Using "Anti Jammer Live Ping" option:
Check table: SELECT max(devicetime) LastLive FROM gps.positions;
and if "LastLive" is more then 2 minutes, - then Send "Anti Jammer Notification"

PS. This set-up requires constantly (each minute) sending GPS tracker packet to Traccar server, and if message is not recieved in two minutes, - then "Anti Jammer Notification" will be triggered.

Thanks.

You can already do it with "offline" event notification.

Thanks for prompt answer.

After what period of time "offline notification" is going to be triggered? 1 min? 2 min?
I do have <entry key='report.trip.greedyParking'>true</entry>. Is this feature not causing issues to "offline notification"? Or I need to switch it off (greedyParking)?
When my device is constnantly on (transmitting each minute) and having below features enabled:
I am still getting fake trips for 5-10 minutes (despite my car is stationary)
```
<entry key='report.trip.greedyParking'>true</entry>
<entry key='distance.enable'>true</entry>
<entry key='coordinates.filter'>true</entry>
<entry key='coordinates.error'>30</entry>
```
To fix above I could suggest implement "home zone" or "parking zones". If car is not leaving this zone, then "trip" is not recorded.

Thanks.

You would have to configure connection timeout. It can be any value that you pick.
It shouldn't cause any issues.
You can adjust trip calculation parameters:
