False geofence enter exit getting generated randomly

anshuljain5 years ago

Hi Anton

I am getting false geofence enter exits randomly. Earlier device was sending the data every second, so I changed it for every 5-10 seconds interval and still its giving false alerts. There is no jumps or anything. Geofence is also quite big.
Please check the below screenshots, and location is not changed much but it is showing geofence enter and exit. Tracker never left the geofence and still it gets the events.
I also checked logs for any errors, but not able to find anything.

It will take time to investigate the issue. I don't have an answer just by looking at the data.

My guess is that the device is reporting locations in the wrong order, so it moves in and out of the geofence.
