Port for Digital Matters Yabby Edge

I am looking for the port for the Digital Matters Yabby Edge and i get this log data.
Started with 5001 port for testing.

You omitted the most important information - HEX data.

It decodes to

I doubt that it's from your Yabby device. Looks more like port testing tool or something like that.

Still looking for Yabby
How about:

Do you have a Chrome installed on your Yabby device?

I don't think, it is stock from Digital Matters

Then I don't think it's from your device.

This looks more like it. Now the problem is that you are using wrong port. You have to use DMTHTTP. Also, you need to build a version from source because I think the protocol support was added very recently.

Great, I was thinking it was DMTHTTP. Is that port 5139?
What do you mean when you say "build a version from source because I think the protocol support was added very recently."

I think i found it on https://www.traccar.org/build/
Thank you
