How to know which port to use?

Hello!

I did install Traccar on my CentOS 6.6 64bits today, but my TK102C device is not saving nothing on mysql database.
I guess all ok with installation, because I was able to send data to database, after execute the command via ssh (suggestion obtained on https://github.com/tananaev/traccar/blob/master/tools/hex.sh ):

echo 3e52505631393535352b343533383431382d303733393531383530303032303231323b49443d393939393b2a37423c0d0a | perl -ne 's/([0-9a-f]{2})/print chr hex $1/gie' > /dev/udp/localhost/5057

Below, I put some output log from traccar:

I also added my device using IMEI 355488339911821

Any suggestion?

Thanks in advance.

It is GT06 protocol, so you should use port 5023 for your device.

WOW!!!! It worked like a charm! Thank you very very much...
Nice job Anton. I really appreciated your job
best regards!
Hugo

take a look at: https://www.traccar.org/devices/
It says devices and ports, and also says if it supported, or not...

Hello,

May you explain how did you figure out the port? I had the same problem and this port worked for me. I tried the Hex decoder and all what I got was garbage. see below:

78780d010352887076539901002176580d0a

here the hex

[removed unnecessary binary data]

Port for your device is 5023.

Thank you Anton,

Yes, as I said it worked for me. My question How can I know from the data itself?

I know because it starts with 7878.
