This example illustates access to all sentence types, using the NMEA library. It assumes that a GPS receiver is connected to serial port 'Serial1' at 4800 bps.

    #include <nmea.h>

    NMEA gps(ALL);    // GPS data connection to all sentence types

    void setup() {
      Serial.begin(9600);
      Serial1.begin(4800);
    }

    void loop() {
      if (Serial1.available() > 0 ) {
        // read incoming character from GPS and feed it to NMEA type object
        if (gps.decode(Serial1.read())) {
          // full sentence received
          Serial.print ("Sentence = ");
          Serial.println (gps.sentence());
          Serial.print ("Datatype = ");
          Serial.println (gps.term(0));
          Serial.print ("Number of terms = ");
          Serial.println (gps.terms());
        }
      }
    }
