Hi I'm currently doing a bit of a project in my college course and currently using an arduino with a few extra features on it like a ESP8266, LED display etc. Anyways, I'm currently having trouble on what is wrong with me code here. I haven't had trouble with it until I put the two functions calls in setup but I'm having trouble now uploading it. I always figured that the function calls must be in setup but it doesn't seem to recognise it in my code.

Code:
#include <SoftwareSerial.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <TinyGPS++.h>

//I2C pins declaration
LiquidCrystal_I2C lcd(0x27, 16, 2);
// SoftwareSerial serial_connection (11, 10);
TinyGPSPlus gps;

const int sensor = A1; // Assigning analog pin A1 to variable 'sensor'
float tempc;  //variable to store temperature in degree Celsius
float tempf;  //variable to store temperature in Fahreinheit
float vout;  //temporary variable to hold sensor reading


#include "WiFiEsp.h"

// Emulate Serial1 on pins 6/7 if not present
#ifndef HAVE_HWSERIAL1
#include "SoftwareSerial.h"
SoftwareSerial Serial1(6, 7); // RX, TX
#endif

char ssid[] = "";            // your network SSID (name)
char pass[] = "";        // your network password
int status = WL_IDLE_STATUS;     // the Wifi radio's status
int reqCount = 0;                // number of requests received

WiFiEspServer server(80);

void setup()
{
  // initialize serial for debugging
  Serial.begin(115200);
  // initialize serial for ESP module
  Serial1.begin(9600);
  // initialize ESP module
  WiFi.init(&Serial1);

pinMode(sensor,INPUT); // Configuring pin A1 as input
Serial.begin(9600);

lcd.begin();//Initializing display
lcd.backlight();//To Power ON the back light
//lcd.backlight();// To Power OFF the back light

  // attempt to connect to WiFi network
  while ( status != WL_CONNECTED) {
    Serial.print("Attempting to connect to WPA SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network
    status = WiFi.begin(ssid, pass);
  }

  Serial.println("You're connected to the network");
  printWifiStatus();
  printGpsGsm();

  // start the web server on port 80
  server.begin();
}
}

void loop()
{
  lcd.setCursor(0,0); //Defining positon to write from first row,first column .
lcd.print(" Dog Tracker");
delay(1000);//Delay used to give a dynamic effect
lcd.setCursor(0,1);  //Defining positon to write from second row,first column .
lcd.print(" Device " );
delay(5000);
lcd.clear();//Clean the screen
lcd.setCursor(0,0);
lcd.print(" IoT Project ");
lcd.setCursor(0,1);
lcd.print(" 2021 ");
lcd.clear();
delay(3000);

vout=analogRead(sensor);
vout=(vout*500)/1023;
tempc=vout; // Storing value in Degree Celsius
tempf=(vout*1.8)+32; // Converting to Fahrenheit
lcd.setCursor(0,0);
lcd.print(" Temparature ");
delay(3000);
lcd.setCursor(0,0);
lcd.print("Degrees=C");
lcd.print(tempc);
lcd.setCursor(0,1);
lcd.print("Fahrenheit=F");
lcd.print(tempf);
delay(10000); //Delay of 10 seconds for ease of viewing in serial monitor
lcd.clear();
delay(5000);

  // listen for incoming clients
  WiFiEspClient client = server.available();
  if (client) {
    Serial.println("New client");
    // an http request ends with a blank line
    boolean currentLineIsBlank = true;
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        Serial.write(c);
        // if you've gotten to the end of the line (received a newline
        // character) and the line is blank, the http request has ended,
        // so you can send a reply
        if (c == '\n' && currentLineIsBlank) {
          Serial.println("Sending response");
         
          // send a standard http response header
          // use \r\n instead of many println statements to speedup data send
          client.print(
            "HTTP/1.1 200 OK\r\n"
            "Content-Type: text/html\r\n"
            "Connection: close\r\n"  // the connection will be closed after completion of the response
            "Refresh: 20\r\n"        // refresh the page automatically every 20 seconds
            "\r\n");

delay(1000);
Serial.write(0x1A);
Serial.write(0x00);
Serial.write(0x0A);
delay(1000);
}
}

And these are the errors I keep getting. I can't seem to find the missing } in the code either.

Move all the '#include' lines to the top of your code.

Then check that "WiFiEspServer server(80);" is the correct code to use for "WiFiEsp.h", my guess is you have it named wrongly, for example should it be "WiFiServer server(80)" perhaps.

I haven't fully followed your code but I suspect you will run into problems by serving the web page in a loop and particularly with the delays in it. Serving a web page repeatedly does not update it in the readers browser. Personally, I would check for the request in the loop() so it isn't missed while in one of the delay routines then when one is received, call a subroutine to publish the web page.

Brian.
