I don't see any problems in the log.
If I send with http command osmand protocol with specific device id I see it at the map go to the correct position. I wait for the tracker to send the gps position, from the log it send the signal but it is not updated to the map. I see it at the previous position I have send through command. Why?
You should check the timestamps. Traccar will always show the latest location by fix time.
I have 3 teltonika and 1 traccar client on a traccar server. Without any change the gps map position is not changing. I have checked the logs and i receive the same gps position from all clients, that is not correct! Any advice?
