How to increase the refresh rate of neo 6m gps module directly in the neoGPS libary . i am using stm32f103

Projects Programming
1 
void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

when i am using this code on the arduino uno it works normally and sends data. when it is used on the stm32 same connections nothing displays.

#include <NMEAGPS.h>


#define gpsPort Serial1
#define GPS_PORT_NAME "Serial1"
#define DEBUG_PORT Serial

int32_t Lat, Long;
static NMEAGPS  gps; // This parses the GPS characters


void setup()
{
  DEBUG_PORT.begin(115200);
 
  while (!DEBUG_PORT);

  DEBUG_PORT.println( F("Looking for GPS device on " GPS_PORT_NAME) );
  DEBUG_PORT.flush();

  gpsPort.begin(9600);
  
}


void loop(){
  // DEBUG_PORT.println( F("Looking for GPS device on " GPS_PORT_NAME) );
  while (gps.available(gpsPort)) {
    
    gps_fix fix = gps.read();
    
    if (fix.valid.location) {
      DEBUG_PORT.print(fix.latitudeL());
      DEBUG_PORT.print(", ");
      DEBUG_PORT.println(fix.longitudeL());
      //DEBUG_PORT.print( fix.speed_mph(), 2 );
      }
    }
}

this code works normally but refresh every second it is slow for my project i want to increase the refresh rate to 10hz.

The code has nothing to do with it. Module default sample rate is 1 Hz. For changing it you should to setup the module itself.
And the short look to the internet showed the maximum GPS sample rate for the module is 5 Hz

To change the refresh rate you can use the u-blox u-center software.

Here is a Sparkfun tutorial for using the u-center software.

ok i know how to do that my problem was that i was afraid that it wipes out when power off

do not afraid, just test it
