Hello, there is a problem on my FMB920 devices. The red line that indicates the track is not correct but is the straight line between two signals so it apears the car to pass from places that it hasn't never been there.There is an unknown reson that the device stops sending data to the server and after a period of time when it starts again sending signals to the server it drows a straight line between the two signals and the intermediate information of the track is missing. This hapends when the vehicle is moving and not when is stationary.
