SinoTrack ST-902L OBD

LoganH2 days ago

Hello, I am having issues trying to sync my Sino Track OBD 902-L Tracker to traccar. I got the sim from hologram.io, and the tracker with me. I activated sim, went through setting the APN, pointing it to my traccar server, etc.. But the SinoTrack is just blinking orange light meaning its GPRS is failing. GPS is solid blue light, GPRS is blinking orange. Any ideas? Been at it for hours. Thanks!

I confirm. A few years worked good with traccar, from 16.8.2025 suddenly stopped working. If I connect them to sinotrack server, they work good.

I use 8 devices Sinotrack st-902 and they all stopped working at the same time.

So are you going to try a different brand? The hologram sim has been nothing but issues aswell

I use also Teltonika OBD, they are working good. Now I tried to connect SinoTrack OBD ST-902 to one of demo traccar servers, and it works good, and there I saw, that there is already new traccar version 3.9.0. I use 3.8.1. version. I will now update my traccar to 3.9.0. and let zou know if this was the solution.

I think you meant to say major version 6, not 3.

I also have spent $20+ on sending SMS to my hologram sim trying to get it to connect to GPRS on the tracker. Have you used that sim before?

yes, upgrading traccar server to 3.9.0 was the solution. Now SinoTrack OBD ST-902 works fine again with traccar.

There's no version 3.9.0. There is 6.9.0.

On the SinoTrack 902-L The orange GPRS light has always been blinking, never seen it a solid orange light.

Thank you for correcting me about the version, Anton. Keep up the good work.

Logan, I'm from Slovenia (EU) and I'm using SIM from german company 1Nce.

Are you able to help with the setup for the 902? Hologram support responded and said its all fine but im getting a bunch of 0-byte data sessions. So it seems it may be a device issue

*if you didn't change the password

This is command to set right APN. Guess you can send sms to your device from your hologram dashboard

Then you have to send SMS command to connect to your traccar server
