devices.positionid, does not update.

I have a problem with the fields, fixtime, latitude, longitude of the position table (they are repeated). and the positionid field of the devices table, does not update.

What can be the detail?

Usually it means that device sends same data, or device doesn't send GPS data, so Traccar uses last known location.

I just forward all the sms commands from the gps, delete the field devices.positionid and restart the service ..

I just added another GPS and the same problem
