Bug Found

Hi,

I found that this is a DATA format issue. The device is sending "SD1" (SD card status) where Traccar expects a number.

I'm just informing, no need for help
Cheers

Without providing the data sample this is not really useful. Ideally also the protocol documentation.

The Gl200TextProtocolDecoder.java is in the original Traccar package 6.11.1 as is

I don't have any access to the device. Device sending data to Port 5004
I requested more info about the configuration, waiting for a response

The sample you provided doesn't have "SD1", so it's decoded just fine.

Yes, position saved correctly, but, with

2026-01-09 13:17:57  WARN: [T9be4a094] error -  For input string: "SD1" - NumberFormatException (... < 

Since about half an hour ago, the error disappeared.

The error is not the sample you provided.
