I use fm3001 (obd2) and traccar receives what the gps reads information through the vehicle's obd2 port then I create calculated attributes to interpret the info received.
I receive this information:
Io31 = 13
Io32 = 83
Io33 = 249
Io35 = 45
Io37 = 40
Io38 = 16
Io39 = 12
Io41 = 0
Io48 = 30
Io68 = 0
Io36 = 1371
Io43 = 0
Io51 = 14300
Io52 = 78
and some more. Then I just have to check the teltonika wiki to know what each Io corresponds to.
I hope it helps you
Just an advice please about how which better to use with traccar
Teltonika FMB003 (ODB2) or Teltonika FMB120
i am asking because i want to know if i used Teltonika FMB003 (ODB2) is this will help me to get more information from car without using additional external sensors like fuel level or something else
Any advice please
