NatureLink NL01, 02, and 03

Hi all,

What port should we use for NatureLink NL01, NL02 and NL03 (OBD)?

Thanks in advance.

any update about this one? the used protocol is JT808, I have tried port 5015 but not working, I also have tried on Wialon and it works properly (to make sure that there is no problem with the device)
