$GPGAA or GPGGA ?

[engeeknyer]

I think this is a syntactic error in the help.

The helps estates that the available parameters for GPS commands are gps $GPGAA or gps $GPGLL or gps $GPRMC. Trying with GPGAA and this returns a syntax error (?). So I think that GPGAA in the help must be changed by GPGGA.

Thanks for that project!
