iStartek VT600

I have one iStartek VT600 gps device and next is extracted logs from the traccar-server.log file for this specific gps device:

According to the documentation, from the gps manufacturer iStartek, the gprs communication seems to be working correctly, but for someone reason I can't see the gps device in the user account as online. Unfortunately I don't have idea how to check if the frame is sending correct data like date/time, latitude, longitude, etc

iStartek GPRS Protocol Between GPS Tracker and Server

any idea why is this occurring?

I found a way to convert the data encoded in HEX to ASCII as follows:

root@mail:~/scripts# echo 2424007e121141207845ff99553139313634312e3030302c412c323534362e373230302c4e2c31303031312e373032342c572c302e30302c34382c3037313132332c2c2a32357c312e347c3433337c323030307c303030302c303030307c303134453030313430353342373834397c31347c3045384233333741ec750d0a | xxd -r -p && echo ''
$$~A xE▒▒U191641.000,A,2546.7200,N,10011.7024,W,0.00,48,071123,,*25|1.4|433|2000|0000,0000|014E0014053B7849|14|0E8B337A▒u

So seems like the gps frame contains a valid gps position according to the iStartek GPRS Protocol document.

Any idea why then the traccar platform is not updating the gps device in the list of devices (map). I have another device with "osmand" protocol and is working fine.

What ports have you tried? Have you tried 5009?

I have tried the port 5222 for iStartek VT600 recommended by Supported Devices, but I'll try this port 5009. Thanks!

The port recognized the protocol but still is not showing as online in the Traccar platform.

It worked!

I can see the device online now. So, the port 5222 is not the correct one or the 5009 is a default for a common Chinese protocol?

Looks like 5222 is not the right one for your device.
