Server not decoding data from device
did you try port 5015?
Trying different port won't help here. You have to check the full connection session. Most likely there's a binary message with non standard length.
Thanks for the replies! I have tried port 5015, no difference there.
Anton I see there one message with non-standard length but it's HEX just like the rest of them and it looks like standard H02 message, just with some assitional attributes. Did you mean this? What can I do to make the decoder work correctly? In the documentation I don't see any Config.xml entries that would look helpful.

All the coordinates are invalid. That's why it's not decoded.
Of course they are invalid, I didn't plan to share my location here :)
However I managed to solve the problem. Just after device connects it send a longer message with many zeros in place of attributes. I figured it's a template for all the messages, so I took that message's length and set it as h02.messageLength in config file. In my case it's 97 bytes. Worked like a charm.
Thanks for your help and replies!
Next time you should probably say that you actually altered the log.
Hi all,
I am trying to connect my ST-901L-4G tracker from Sinotrack to Traccar server that I set up on my own Linux server. According to logs the server receives the messages with GPS coordinates in the time interval that I set up on device but they are not decoded. Weird thing is, sometimes they do get decoded - I can see cordinates successfully decoded for a couple of messages after connection sometimes but then it stops and all I get are HEX coded strings again. Can somebody help me with this, please?
The tracker is configured to send data to port 5013.
iptables:
(with relevant ports open on network as well, other server applications are communicating no problem)
config.xml:
<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'> <properties> <!-- Documentation: https://www.traccar.org/configuration-file/ --> <entry key='database.driver'>org.h2.Driver</entry> <entry key='database.url'>jdbc:h2:./data/database</entry> <entry key='database.user'>[name]</entry> <entry key='database.password'>[pass]</entry> <entry key='notificator.types'>traccar</entry> <entry key='notificator.traccar.key'>[my_key]</entry> <entry key='decoder.timezone'>UTC</entry> </properties>log with decoded messages:
log where nothing gets decoded:
Thanks!
