The error above appears when I try to connect a tk106 device. After this logs, nothing else are catched by the log file but the device appears connected normaly, however without send any positions.
Can anyone help me?

What protocol are you using? Do you have any computed attributes?

I have tested it in demo server 1 traccar yet, but the same error occurred

Same error on demo server? How did you get demo server logs?
