The newest code i have posted works 100%! So if you have similar problems with that aweful gps, use this!
Apparently, TinyGPS and TinyGPS++ don't work well with this gps. To be precice, there is a problem with the gps.encode(c) function.
So using if (gps.encode(c)) most of the times returns false, except some rare occasions which returns true and then you can do some processing...
My last code takes care of that problem by checking continuously, using a do...while loop. If if (gps.location.isValid()) returns true, which means i have valid data, then i do the processing i want and end the do...while loop.
NOTE: This code is for TinyGPS++ library. Same theory will work for TinyGPS too of course...
Here it is:
#include <TinyGPS++.h>
#include <SoftwareSerial.h>
#define GPS_RX_PIN 2
#define GPS_TX_PIN 3
TinyGPSPlus gps;
SoftwareSerial ss(GPS_RX_PIN, GPS_TX_PIN);
void setup()
{
Serial.begin(9600);
ss.begin(4800);
}
char clat[11];
char clng[11];
void loop()
{
bool isGpsLocationValid = false;
do
{
while (ss.available()>0)
{
char c = byte(ss.read());
if (gps.encode(c)) //i previously used if(gps.encode(ss.read())); but no luck then
{
if (gps.location.isValid())
{
dtostrf(gps.location.lat(), 11, 6, clat);
dtostrf(gps.location.lng(), 11, 6, clng);
isGpsLocationValid = true;
}
}
}
} while (isGpsLocationValid = false);
Serial.write(clat);
Serial.println();
Serial.write(clng);
}
