The JT808 protocol has many modifications, so sometimes problems arise with connecting devices that work using it.
First of all, we recommend that you change the device type in application to Sinotrack ST-905.
After that, you can try the following devices in descending order:
TK-Star TK905
Icar GPS
Sinocastel
Gosafe
Gosafe G1C
Huabao
Please note that after changing the device type in the application, the tracker must be redirected to the appropriate server and port, which will be specified in the application.
If you are unable to connect your tracker to our platform, please write to us at support@gps-trace.com with the login, unit ID, screenshot of device configuration (SMS commands and device’s answers) and link to this topic, then we will try to check additionally and help you.
