Hi.
It's simple.
const char* time = fuGPS.getField(1);
You have also available public fields:
byte Hours, Minutes, Seconds;
byte Days, Months, Years;
Example:
byte minutes = fuGPS.Minutes;
from fugps.
from fugps.
Sorry, but everything works on my side:
stream.print(String(fuGPS.Years) + "." + String(fuGPS.Months) + "." + String(fuGPS.Days));
Date is stored in RMC message.
Library needs at least one message of that type to parse date. Maybe your module is wrongly configured.
fuGPS.sendCommand(FUGPS_PMTK_API_SET_NMEA_OUTPUT_RMCGGA);
You can always check out demo programs to display detailed data or connect the module directly to the serial port and see what is being sent.

#include <FuGPS.h>
#define NMEA_RX1 44
#define NMEA_TX1 43
FuGPS fuGPS(Serial1);
bool gpsAlive = false;
void setup()
{
Serial.begin(115200);
Serial1.begin(38400, SERIAL_8N1, NMEA_RX1, NMEA_TX1);
fuGPS.sendCommand(FUGPS_PMTK_SET_NMEA_BAUDRATE_38400);
// fuGPS.sendCommand(FUGPS_PMTK_SET_NMEA_UPDATERATE_1HZ);
fuGPS.sendCommand(FUGPS_PMTK_API_SET_NMEA_OUTPUT_RMCGGA);
}
void loop()
{
// Valid NMEA message
if (fuGPS.read())
{
// We don't know, which message was came first (GGA or RMC).
// Thats why some fields may be empty.
gpsAlive = true;
Serial.print("Quality: ");
Serial.println(fuGPS.Quality);
Serial.print("Satellites: ");
Serial.println(fuGPS.Satellites);
Serial.print("Date: ");
Serial.println(fuGPS.Days);
Serial.print("Month: ");
Serial.println(fuGPS.Months);
Serial.print("Year: ");
Serial.println(fuGPS.Years);
if (fuGPS.hasFix() == true)
{
// Data from GGA message
Serial.print("Accuracy (HDOP): ");
Serial.println(fuGPS.Accuracy);
Serial.print("Altitude (above sea level): ");
Serial.println(fuGPS.Altitude);
// Data from GGA or RMC
Serial.print("Location (decimal degrees): ");
Serial.println("https://www.google.com/maps/search/?api=1&query=" + String(fuGPS.Latitude, 6) + "," + String(fuGPS.Longitude, 6));
}
}
// Default is 10 seconds
if (fuGPS.isAlive() == false)
{
if (gpsAlive == true)
{
gpsAlive = false;
Serial.println("GPS module not responding with valid data.");
Serial.println("Check wiring or restart.");
}
}
}
here is the code i am running and i dont receive date, everything(not including speed) but date
from fugps.
found the problem in the FuGPS library, the value of tokensCount should be compared to 14 and not 13
from fugps.
@MeY0u there is no problem with the library. RMC message has 13 tokens including message id:
https://aprs.gids.nl/nmea/#rmc
eg1. $GPRMC,081836,A,3751.65,S,14507.36,E,000.0,360.0,130998,011.3,E*62
eg2. $GPRMC,225446,A,4916.45,N,12311.12,W,000.5,054.7,191194,020.3,E*68
eg3. $GPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,130694,004.2,W*70
1 2 3 4 5 6 7 8 9 10 11 12
Perhaps your GPS module sending data out of standard. That's why it's better to display all incoming messages to analyze.
from fugps.
i use ATGM332D-5NR32 and i print the currentbuffer variable from the library and i didnt notice any difference between the standard and what i sends back.
all the tokens are at the correct index as you set it.
By the way, the library is pretty easy to modify, thats great bonus thank you.
