VM6500S how to set obddongle protocol

Hi I have VM6500S Chinese device I'm trying to connect
I've found that it's protocol in traccar source code https://github.com/traccar/traccar/blob/master/src/main/java/org/traccar/protocol/ObdDongleProtocolDecoder.java

As far as I understand the protocol called obddongle in traccar terms.
I've google it and found some refecences <entry key='obddongle.port'>5115</entry>
So I set the port to 5115
But I still see it is identified as gps103

Is 5115 a correct port for obddongle?
Maybe I should force it in traccar config (https://www.traccar.org/configuration-file/) ?

If you see gps103, it means that your device is reporting to the port gps103 (5001 default).

Thank you that's what I thought.
But is 5115 port correct for obddongle protocol?

You can check default ports here or in the default config file:

https://www.traccar.org/devices/

Of course, I've checked it before bothering you
The thing that I don't see any information about obddongle protocol or 5115 port there https://www.traccar.org/devices/
I decided that the port is 5115 since I found this line in /conf/default.xml

<entry key='obddongle.port'>5115</entry>

If it's 5115 in the config, it should be 5115.
