Expected Behavior

Plugin should always post my current accurate location on server.

Actual Behavior

Sometimes, it sends the correct location. However, within the next minute, it updates a location that is several kilometers away from the actual position. This behavior is causing inconsistencies in the location data we store. Forexample I am in Bury some locations are correct after sometimes the location I receive on server log is of Bolton

We need this to be fixed ASAP as we are having issues while delivering our orders

The plug-in does not manufacture locations — it is a mailman delivering what the native location api provides to it.

how is the plug-in supposed to know whether Bolton or Bury is reality?

You’re expected to perform your own filtering (see location.coords.accuracy).

If I am in Bury and moving in some park why do I get the locations from Bolton my question is tha

[christocracy]

See wiki “Debugging”. Learn to fetch logs from the plug-in using “.emailLog”.

Also, provide a map of your location tracking. Or use the demo server (see api docs “Config.transistorAuthorizationToken” to learn how to configure the plug-in to post data to my demo server where I can visualize it)
