I have buy 5 new teltonika FMB202 and i face a problem with answer from device.
When i send a 'getgps' command or 'ggps' command, device return answer with an old position (every time sms have same wrong long&lat but time is correct). Configurator and bluetooth app shows the correct position.
I reset everything and try many settings.
I make a firmware update from 3.10.08.00 to 3.18.19.00 but the problem still exists.
My big problem is that i can't check the rest 4 device because is on client and not moving for now.
