Arduino and GPS module

Projects Programming

Hi all,
I'm try to used Arduino interface with the GPS module. My Arduino read NMEA data from GPS module and display on serial monitor.
This is my Arduino code:

#include <SoftwareSerial.h>

SoftwareSerial gpsSerial(2, 3);

char buffer[90];
int i;

void setup() { 
  Serial.begin(9600);
  gpsSerial.begin(9600);   
}

void loop() { 
  readline();
  Serial.println(buffer);  
}

void readline(void) {
  char c;
  char bufferindex = 0;
  if (bufferindex == 0) {
    while (c != '

And this is output:

$
GPGLL,1351.49109,N,10039.37870,E,171319.00,A,A*66

But, I want output like this:

$GPRMC,171319.00,A,1351.49109,N,10039.37870,E,0.167,,150314,,,A*7D

$GPGLL,1351.49109,N,10039.37870,E,171319.00,A,A*66

Please help me to fix the output.) {
      c = gpsSerial.read();
      if (c == -1)
        continue;
      Serial.print(c);
      if (c == '\n')
        buffer[bufferindex+1] = 0;
      bufferindex++;
      if (bufferindex == 89) {
        Serial.print('!');
        bufferindex = 0;
      }
    }
  }
}


And this is output:

§DISCOURSE_HOISTED_CODE_1§


But, I want output like this:

§DISCOURSE_HOISTED_CODE_2§


Please help me to fix the output.

Stop printing anything in readLine(). Add the $ to the array.

I'm not an expert but today I found the easy way to fix this problem.
This is new code:

#include <SoftwareSerial.h>

SoftwareSerial gpsSerial(2, 3);

char buffer[90];
int i;

void setup() { 
  Serial.begin(9600);
  gpsSerial.begin(9600);   
}

void loop() { 
  readline();
  Serial.print(buffer);  
}

void readline(void) {
  char c;
  char bufferindex = 0;
  if (bufferindex == 0) {
    while (c != '

) {
      c = gpsSerial.read();
      if (c == -1)
        continue;
      Serial.print(c);
      if (c == '\n')
        buffer[bufferindex+1] = 0;
      bufferindex++;
      if (bufferindex == 89) {
        Serial.print('!');
        bufferindex = 0;
      }
    }
  }
}

This is new code:

I guess I'm not spotting the differences.

Refer to loop, I just change from "Serial.println(buffer);" to "Serial.print(buffer);".
