JT808 Protocol Support

I understand and find that certain devices of this protocol are working in huabao protocol on port 5015.

However there is not much information getting read in traccar apart from position update. Can anyone please guide which protocol is write for Jointtech etc.

If the position is decoded correctly, you already found the right port. There's no other port that would work.

Then why all parameters are not getting decoded ?? Is there any option to type model like you have in teltonika protocol… which will decode all values
