Question

我的项目有问题。我正在将SIM800L和GPS Neo6MV2与arduino真正的uno一起使用。我的项目正在通过消息发送GPS位置。但是，我收到的消息仅包含long = 0,000000 lat = 0，000000。这是我的代码：

#include <TinyGPS++.h>
TinyGPSPlus gps;
//float latitude, longitude;
int myled=13;
#include <SoftwareSerial.h>
SoftwareSerial SIM800L(7, 8);
//SoftwareSerial gps_serial(2,3);
String response;
int lastStringLength = response.length();
String latitude, longitude;
String link;
void setup() {
  Serial.begin(9600);
  Serial.println("GPS Mulai");
    SIM800L.begin(9600);  
    SIM800L.println("AT+CMGF=1");
    Serial.println("SIM800L started at 9600");
    delay(1000);
    Serial.println("Setup Complete! SIM800L is Ready!");
    SIM800L.println("AT+CNMI=2,2,0,0,0");
    gps.encode(Serial.read()); 
      latitude = gps.location.lat();
      longitude = gps.location.lng();
}
void loop() {
    if (gps.location.isValid())
  {
    Serial.print(gps.location.lat(), 6);
    Serial.print(F(","));
    Serial.print(gps.location.lng(), 6);
  }
  else
  {
    Serial.print(F("INVALID"));
  }
  if (SIM800L.available()>0){
      response = SIM800L.readStringUntil('\n');
    }
   if(lastStringLength != response.length()){

}

      if(response.indexOf("ON") == 4){

          SIM800L.println("AT+CMGF=1");    //Sets the GSM Module in Text Mode
          delay(1000);  // Delay of 1000 milli seconds or 1 second
          SIM800L.println("AT+CMGS=\"082232949301\"\r"); // Replace x with mobile number
          delay(1000);
          SIM800L.println("https://www.google.com/maps?q=" + latitude+","+longitude) ;// The SMS text you want to send
          delay(100);
          SIM800L.println((char)26);// ASCII code of CTRL+Z
          delay(1000);
      }
  }

您能帮我解决这个问题吗？

我的GPS无法通过短信分享位置
