database.updateLatestPosition error

How could you clean the server cache from time to time?

Anton Tananaev8 years ago

Latest positions can only be cleared by restart.

And you could not put an improvement to the software, so that the last position of the device that is in cache is the last one that has sent?

Not all devices send data in the correct order, so the "latest" one can only be determined by the timestamp.
