I am using a arduino uno and neo 6m gps module. The problem I am facing is quite weird. When I connected the setup the data from neo6M was seen in serial monitor, I even printed it on a Oled display. It was a close room at night. I used tiny gps plus plus library to parse the data. I got both latitude longitude. After disconnected the circuit i tried again and that is when nothing came out in serial monitor. The same sketch did not work for a day. But again at afternoon at some point i got the data properly. Sometimes the red led is blinking but nothing happens. While I change the rx and tx pins in software serial it got data but then again same problem and changing pins don't work. I have tested it in front of my window so there must be a good signal. Can someone tell me what is wrong with the system? I have so far waited long enough like 10 mins to get the data but nothing. I have to present the project by tomorrow in office. This is the code :
#include <TinyGPS++.h>
#include <SoftwareSerial.h>
// Choose two Arduino pins to use for software serial
int RXPin = 2;
int TXPin = 3;
int GPSBaud = 9600;
// Create a TinyGPS++ object
TinyGPSPlus gps;
// Create a software serial port called "gpsSerial"
SoftwareSerial gpsSerial(RXPin, TXPin);
void setup()
{
// Start the Arduino hardware serial port at 9600 baud
Serial.begin(9600);
// Start the software serial port at the GPS's default baud
gpsSerial.begin(GPSBaud);
}
void loop()
{
// This sketch displays information every time a new sentence is correctly encoded.
while (gpsSerial.available() > 0)
if (gps.encode(gpsSerial.read()))
displayInfo();
// If 5000 milliseconds pass and there are no characters coming in
// over the software serial port, show a "No GPS detected" error
if (millis() > 5000 && gps.charsProcessed() < 10)
{
Serial.println("No GPS detected");
while(true);
}
}
void displayInfo()
{
if (gps.location.isValid())
{
Serial.print("Latitude: ");
Serial.println(gps.location.lat(), 6);
Serial.print("Longitude: ");
Serial.println(gps.location.lng(), 6);
Serial.print("Altitude: ");
Serial.println(gps.altitude.meters());
}
else
{
Serial.println("Location: Not Available");
}
Serial.print("Date: ");
if (gps.date.isValid())
{
Serial.print(gps.date.month());
Serial.print("/");
Serial.print(gps.date.day());
Serial.print("/");
Serial.println(gps.date.year());
}
else
{
Serial.println("Not Available");
}
Serial.print("Time: ");
if (gps.time.isValid())
{
if (gps.time.hour() < 10) Serial.print(F("0"));
Serial.print(gps.time.hour());
Serial.print(":");
if (gps.time.minute() < 10) Serial.print(F("0"));
Serial.print(gps.time.minute());
Serial.print(":");
if (gps.time.second() < 10) Serial.print(F("0"));
Serial.print(gps.time.second());
Serial.print(".");
if (gps.time.centisecond() < 10) Serial.print(F("0"));
Serial.println(gps.time.centisecond());
}
else
{
Serial.println("Not Available");
}
Serial.println();
Serial.println();
delay(1000);
}
