I am developing New Hardware Firmware

I am forwarding data received from the device to the remote pc putty terminal forwarded from the Traccar server. I am debugging data received from device using forward.url at config file, the format as below

data={uniqueId};{latitude};{longitude};{deviceTime};{fixTime};{valid};{altitude};{speed};{course};{statusCode};{attributes};

1- What's the code list of {statusCode} variable?
2- Can I remove not necessary variables from the string?
3- Do I need to forward the <;> character at the end of the string?

Thank you

1. Check source code.
2. Yes.
3. No.

Thank you
