Suntech decode issue

Hi, I’m using traccar server.
Everything was ok, but when I set up an st940 I get an error for input string on suntechProtocolDecode method.
Does anyone know how to fix this error?
Thanks

Logs?

What's your server version? Did you make any config changes?

is the 4.10. I did, but only on traccar.xml on database connection. I´m using mysql

I realized this parameter has this structure CELL ID (4 hex digits), Location Code (4 hex digits) And Serving Cell 2 dec digits.
this parameter is called CELL on the st940 manual

You need to set suntech.protocolType to 1 in the config or device attributes.

Ok. How can i do that?

Read documentation.

I have read the documentation, but I didn’t see protocolType parameter. Can you please give me a new lead to get this done?

This is what you need:

I did the change and it worked. You’re the man Anton

Great, with the link you sent I was analyzing and I believe it may be at this point in the code but I can't identify.

For support would it be an email reporting the problem like here and will the hours be calculated with value?

case "UEX":
                int remaining = Integer.parseInt(values[index++]);
                double totalFuel = 0;

                    String attribute = values[index++];
                    if (attribute.startsWith("CabAVL")) {
                        String[] data = attribute.split(",");
                        double fuel1 = Double.parseDouble(data[2]);
                        if (fuel1 > 0) {

What exactly does the next config changes? couldn't find any documentation about it.

Will it affect newer suntech devices if activated? where can I find more info about this config?
