Disregard the protocol documentation, use this one instead:

Have you tried TRV protocol?
Yes, thank you, it works.
What about the protocol I posted in the OP? Chinese technician keeps asking me about a port but won't give me configuration commands, so I can't check hexes in traccar log file. Are you able to recognize the protocol just by looking at documentation?
I followed troubleshooting guide and I couldn't fit this hex
5452564150303033353236323131303934383032323523
, which translates toTRVAP00352621109480225#
, into any protocol from the guide. I've also got a protocol documentation from a chinese technician, here: https://www.mediafire.com/file/yu6bauba076qr0l/OBD-II_communication_Protocol_BY-A6.pdf/file
