Which protocol is this and how to add more "fields" to it?

Ma year ago

Hi everyone,

I am looking at: https://www.traccar.org/identify-protocol/

But I don't see any protocol listed that looks like this string which is what Freematics devices send to Traccar:

5543464c4646594623303a3936323139322c3130443a35302c3130433a313030302c3131313a32302c3130343a34392c32343a313139312c32303a303b2d302e30333b302c38

Which translates to:

UCFLFFYF#0:962192,10D:50,10C:1000,111:20,104:49,24:1191,20:0;-0.03;0,8

Which protocol is this? and how can one add extra fields to it (such as MIL status) and have that appear in Traccar?

Thank a lot

Have you tried the standard Freematics port (5170)?

I am using port 5170 already. My question is more about the protocol in use and how to extend it.

I'm confused. You're using Freematics protocol and you're asking which protocol it is?

Ma year ago

My apologies, I did not know there was a "freematics protocol".

Would documentation for sending extra info to Traccar (such as MIL light status) be found in Traccar's documentation or in Freematics' documentation or both?

I am trying to display if a vehicle has any DTC codes in the Traccar interface.

There's probably some documentation on the Freematics website, but you can also check the decoder class to see what's supported.

Thank you.

Sorry what is the decoder class, and where do I find that?

In the source code.
