I have a Teltonika FMB 910 device which can send data to the server properly. However, there is something confusing where the data is sent several times in duplicate when the courses are different. I have set the acquisition data according to the standards from Teltonika for min angle = 10.
The device may transmit data based not only on the min period but also on changes in angle, distance, or speed delta.
In case If any of these conditions are met, the device will transmit packet data to the server,
If unsure about data sending and assume it as Duplicate data then set all values for angle, distance and speed delta to 0,
Test the device under these conditions and keep only the min period enabled during data acquisition.
