Arduino Uno and Neo-6m GPS help

[slinky]

Hello everyone,

Quick question for the more code savvy individuals on this site. I have a Neo -6m GPS module connected to an Arduino UNO. The problem I have is my Uno cannot "handle" both position data and time data at the same time. For example, I can serial print both latitude and longitude and the serial monitor will output the correct values. I can serial print both hour and minute and the serial monitor will output the correct values. But i cannot serial print latitude, longitude, hour, and minute at the same time. My serial monitor will output zeroes for each value. Here is the code I am using.

#include <TinyGPS++.h>
#include <SoftwareSerial.h>
SoftwareSerial gpsSerial(3, 4); //rx,tx
TinyGPSPlus gps;


void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  gpsSerial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:

  while (gpsSerial.available() > 0) {

    gps.encode(gpsSerial.read());
    Serial.print(gps.location.lat());
    Serial.print("  ");
    Serial.println(gps.location.lng());
    Serial.print("  ");
    Serial.print(gps.time.hour());
    Serial.print("  ");
    Serial.println(gps.time.minute());
  }
  Serial.println("NO DATA");
}

I think the input buffer is overflowing because you are spending far too much time printing.
Start with a faster output rate:
Serial.begin(115200);

Then only print when a full message has been processed:

  while (gpsSerial.available() > 0)
    if (gps.encode(gpsSerial.read()) {

The function gps.encode() returns 'true' if the character processed completes a message. If it doesn't, there is no chance that any values have changed.

Yep, that corrected the problem. Thank you very much for the swift response!
