GPS indication
I did not change. Now it is working. Will it be alright now? Do I have to be careful about something?
If you configured filtering you should be fine.
In which table can I adjust the km?
It's about trips
Possibly how to improve it?
Trips are not stored anywhere. They are calculated on the fly based on device data.
It remains to delete entries from the table Postions ?
Have you updated "devices" table as well? If yes and still doesn't start, what's the error in logs?
