distance report 0.00 problem

hello, im using version 3.9, i enable distance on config file. my problem is when i make a summary report in the distance section i get 0.00 km.

how i can enable distance in the report seccion?

Usually it happens when your device reports constant odometer value in every message.

im using tk103 protocol. how i can fix that. is there a solution?

You can set "report.ignoreOdometer" parameter in the config to "true".
