Hi,

well the comments says that the baud rate should be 4800, but your code (just below the comment) sets baud rate to 9600.

/**
 * D1 - TX pin (RX on the GPS module side)
 * D0 - RX pin (TX on the GPS module side)
 * 4800 - GPS baud rate
 */
SerialGPS gps(P4_22, P4_23,9600);

For 4800 baud rate it shows output as "Overflowed message limit" so i kept 9600 but the output is always zero

Maybe you should write the serial data coming from the gps to the pc serial port. Just to look at the data that is coming from the gps module.
