So i tried modifying the "simple_test" sketch from TinyGPS examples. Here is the code:
#include <SoftwareSerial.h>
#include <Bridge.h>
#include <TinyGPS.h>
/* This sample code demonstrates the normal use of a TinyGPS object.
It requires the use of SoftwareSerial, and assumes that you have a
4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
*/
TinyGPS gps;
SoftwareSerial ss(9, 8);
void setup()
{
Serial.begin(115200);
ss.begin(9600);
Bridge.begin();
Serial.print("Simple TinyGPS library v. "); Serial.println(TinyGPS::library_version());
Serial.println("by Mikal Hart");
Serial.println();
}
void loop()
{
bool newData = false;
unsigned long chars;
unsigned short sentences, failed;
// For one second we parse GPS data and report some key values
for (unsigned long start = millis(); millis() - start < 1000;)
{
while (ss.available())
{
char c = ss.read();
// Serial.write(c); // uncomment this line if you want to see the GPS data flowing
if (gps.encode(c)) // Did a new valid sentence come in?
newData = true;
}
}
if (newData)
{
float flat, flon;
unsigned long age;
gps.f_get_position(&flat, &flon, &age);
Serial.print("LAT=");
Serial.print(flat == TinyGPS::GPS_INVALID_F_ANGLE ? 0.0 : flat, 6);
Serial.print(" LON=");
Serial.print(flon == TinyGPS::GPS_INVALID_F_ANGLE ? 0.0 : flon, 6);
Serial.print(" SAT=");
Serial.print(gps.satellites() == TinyGPS::GPS_INVALID_SATELLITES ? 0 : gps.satellites());
Serial.print(" PREC=");
Serial.print(gps.hdop() == TinyGPS::GPS_INVALID_HDOP ? 0 : gps.hdop());
Serial.print(" ");
int year;
byte month, day, hour, minute, second, hundredths;
gps.crack_datetime(&year, &month, &day, &hour, &minute, &second);
// Serial.print(" ");
// Serial.print(month, DEC); Serial.print("/");
// Serial.print(day, DEC); Serial.print("/"); Serial.print(year);
// Serial.print(" ");
// Serial.print(hour, DEC); Serial.print(":");
// Serial.print(minute, DEC); Serial.print(":"); Serial.println(second, DEC);
SetTime();
}
// gps.stats(&chars, &sentences, &failed);
// Serial.print(" CHARS=");
// Serial.print(chars);
// Serial.print(" SENTENCES=");
// Serial.print(sentences);
// Serial.print(" CSUM ERR=");
// Serial.println(failed);
// if (chars == 0)
// Serial.println("** No characters received from GPS: check wiring **");
}
void SetTime()
{
int year;
byte month, day, hour, minute, second, hundredths;
gps.crack_datetime(&year, &month, &day, &hour, &minute, &second, &hundredths);
char sz[32];
sprintf(sz, "%02d/%02d/%02d %02d:%02d:%02d ",
month, day, year, hour, minute, second);
Serial.println(sz);
Process Set;
Set.begin("date --set");
Set.addParameter("year-month-day hour:minute:second");
Set.run();
}
No luck though. This is seriously frustrating. When I SSH into the Linino side, the "date" command returns a date from like Aug 2013. BTW, the modified part is in the function SetTime(). I'm still able to manually set the date though.
