GNSS

Post by gn19940720 » Thu May 30, 2019 3:12 am

Hi,

I use the library from the site: https://github.com/Seeed-Studio/WioLTE_ ... no_Library
and I had tried the gnss example and get things like below
************************************************************************

$GNRMC,,V,,,,,,,,,,N*4D
$GNVTG,,,,,,,,,N*2E
$GNGGA,,,,,,0,00,99.99,,,,,,*56
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GPGSV,1,1,01,30,,,44*7B
$GLGSV,1,1,00*65
$GNGLL,,,,,,V,N*7A
$GNRMC,,V,,,,,,,,,,N*4D
$GNVTG,,,,,,,,,N*2E
$GNGGA,,,,,,0,00,99.99,,,,,,*56
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GPGSV,1,1,04,07,,,43,17,,,38,18,,,39,30,,,44*70
$GLGSV,1,1,00*65
$GNGLL,,,,,,V,N*7A
$GNRMC,,V,,,,,,,,,,N*4D
$GNVTG,,,,,,,,,N*2E
$GNGGA,,,,,,0,00,99.99,,,,,,*56
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GPGSV,2,1,06,07,,,44,09,,,41,17,,,40,18,,,41*79
$GPGSV,2,2,06,28,,,40,30,,,45*73
$GLGSV,1,1,00*65
$GNGLL,,,,,,V,N*7A
************************************************************************

However, I want to get the str_longitude and str_latitude,
so I try the code like below:
************************************************************

#include <ublox_sara_r4_gnss.h>

UBLOX_SARA_R4_GNSS gnss = UBLOX_SARA_R4_GNSS();

void setup()
{
// Open GNSS module
gnss.open_GNSS();
delay(3000);
SerialDebug.println("_Start");
}

void loop() {
char buffer[64];
if(gnss.getCoordinate()){
SerialDebug.print("GNSS: ");
SerialDebug.print(gnss.longitude, 6);
SerialDebug.print(",");
SerialDebug.println(gnss.latitude, 6);
SerialDebug.print(gnss.str_longitude);
SerialDebug.print(",");
SerialDebug.println(gnss.str_latitude);
} else{
SerialDebug.println("Error!");
}

delay(1000);
}

**************************************************************

but i didn't recieve any response
How can I get the GNSS data from WioLTE_Cat_NB1 ?

Thank You .
