port identification

Bog2 years ago

hello.I followed your instruction to determine what is the right port/protocol for my gps tracker.This is the decode of the log file in traccar.Can you help me?

POST /hmsg HTTP/1.1
Host: My server IP:5001
Accept: */*
User-Agent: QUECTEL_MODULE
Connection: Keep-Alive
Content-Type: application/x-www-form-urlencoded
Content-Length: 136

gps103 < 93.122.211.95] 504f5354202f686d736720485454502f312e310d0a486
error - begin 21, end 24, length 21 - StringIndexOutOfBoundsException (... < Gps103ProtocolDecoder:408 < ExtendedObjectDecoder:52 < ... < WrapperContext:102 < ...)

and this are 2 more samples in the traccar log file
Please give me some help.Thank you!

Looks like it never sends the content. You should try one of the HTTP-based protocol. For example, port 5055.
