GT-U7 GPS Returning Lat/Long of 0.000000

[21qhaverstick]

We have been using a GT-U7 GPS with an Arduino MEGA2560 for our project, but when we test the GPS with the TinyGPS++ it just returns the following:

The code we have been using is as follows, and should be working:

#include <TinyGPS++.h>
TinyGPSPlus gps;

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

void loop() {
while (Serial1.available() > 0) {
gps.encode(Serial1.read());
Serial.print("LAT="); Serial.println(gps.location.lat(), 6);
Serial.print("LONG="); Serial.println(gps.location.lng(), 6);
Serial.print("ALT="); Serial.println(gps.altitude.feet());
Serial.print("SPEED="); Serial.println(gps.speed.mph());
}
}

Any feedback would be greatly appreciated!

You have the GPS outside with a good view of the Sky ?

[21qhaverstick]

Yes, we have the GPS in clear view of the sky and the NMEA data is all correct, but we're having issues with the TinyGPS++ Library returning values of 0.0000

And you’re not just off the coast of Africa in the Atlantic Ocean?

There is some instructions on troubleshooting a GPS here, including a short program that will copy the GPS output to the Serial monitor so you can see what is going on;

My GPS does not work

@21qhaverstick

void loop() {
while (Serial1.available() > 0) {
gps.encode(Serial1.read());
Serial.print(“LAT=”); Serial.println(gps.location.lat(), 6);
Serial.print(“LONG=”); Serial.println(gps.location.lng(), 6);
Serial.print(“ALT=”); Serial.println(gps.altitude.feet());
Serial.print(“SPEED=”); Serial.println(gps.speed.mph());
}

With this bit of code, every time you read a single character from the GPS, you print a great big pile of stuff to the serial monitor, so likley missing essential characters from the GPS in the process.

Where did the 'code' come from ?

Have you tried the examples from the library ?
