Sim 808 module power on and send no location cordinations

[adeepak]

I'm working on a project where I'm using a SIM808 module with an Arduino to get GPS coordinates and send them to my Arduino. The problem is that even though the GPS power turns on, I'm not getting any coordinates.This same code works week before on the same location and gave cordinates.

#include <DFRobot_sim808.h>
#include <SoftwareSerial.h>

#define MESSAGE_LENGTH 160
char lat[12];
char lon[12];
char wspeed[12];

#define PIN_TX 10
#define PIN_RX 11
SoftwareSerial mySerial(PIN_TX, PIN_RX);
DFRobot_SIM808 sim808(&mySerial); // Connect RX,TX,PWR,

void getGPS();

void setup()
{
  mySerial.begin(9600);
  Serial.begin(9600);

  //******** Initialize sim808 module *************
  while (!sim808.init())
  {
    Serial.print("Sim808 init error\r\n");
    delay(1000);
  }
  delay(3000);

  Serial.println("SIM Init success");

  Serial.println("Init Success, sending location every 30 seconds!");
}

void loop()
{
  // Get GPS location
  getGPS();

  // Wait for 30 seconds before reading GPS again
  delay(30000);
}

void getGPS()
{
  while (!sim808.attachGPS())
  {
    Serial.println("Open the GPS power failure");
    delay(1000);
  }
  delay(3000);

  Serial.println("Open the GPS power success");

  while (!sim808.getGPS())
  {
  }

  Serial.print("latitude :");
  Serial.println(sim808.GPSdata.lat);
  Serial.print("longitude :");
  Serial.println(sim808.GPSdata.lon);
  Serial.print("speed_kph :");
  Serial.println(sim808.GPSdata.speed_kph);
  Serial.print("heading :");
  Serial.println(sim808.GPSdata.heading);
  Serial.println();

  float la = sim808.GPSdata.lat;
  float lo = sim808.GPSdata.lon;
  float ws = sim808.GPSdata.speed_kph;

  dtostrf(la, 4, 6, lat);
  dtostrf(lo, 4, 6, lon);
  dtostrf(ws, 6, 2, wspeed);

  Serial.println("Location:");
  Serial.print("Latitude : ");
  Serial.println(lat);
  Serial.print("Longitude : ");
  Serial.println(lon);

  // Create and print the map link
  char mapLink[150];
  snprintf(mapLink, sizeof(mapLink), "Map Link: http://maps.google.com/maps?q=%s,%s", lat, lon);
  Serial.println(mapLink);
  Serial.println();
}
