I am working on esp8266 module with arduino uno board. This is my program.

#include <SoftwareSerial.h>
 
#define DEBUG true
 
SoftwareSerial esp8266(2,3); // make RX Arduino line is pin 2, make TX Arduino line is pin 3.
                             // This means that you need to connect the TX line from the esp to the Arduino's pin 2
                             // and the RX line from the esp to the Arduino's pin 3
void setup()
{
  Serial.begin(9600);
  esp8266.begin(9600); // your esp's baud rate might be different
   Serial.print("START");
  pinMode(11,OUTPUT);
  digitalWrite(11,LOW);
  
  pinMode(12,OUTPUT);
  digitalWrite(12,LOW);
  
  pinMode(13,OUTPUT);
  digitalWrite(13,LOW);
   
  sendData("AT+RST\r\n",2000,DEBUG); // reset module
  sendData("AT+CWMODE=2\r\n",1000,DEBUG); // configure as access point
  sendData("AT+CIFSR\r\n",1000,DEBUG); // get ip address
  sendData("AT+CIPMUX=1\r\n",1000,DEBUG); // configure for multiple connections
  sendData("AT+CIPSERVER=1,80\r\n",1000,DEBUG); // turn on server on port 80
}
 
void loop()
{
  if(esp8266.available()) // check if the esp is sending a message 
  {
 
    
    if(esp8266.find("+IPD,"))
    {
     delay(1000); // wait for the serial buffer to fill up (read all the serial data)
     // get the connection id so that we can then disconnect
     int connectionId = esp8266.read()-48; // subtract 48 because the read() function returns 
                                           // the ASCII decimal value and 0 (the first decimal number) starts at 48
          
     esp8266.find("pin="); // advance cursor to "pin="
     
     int pinNumber = (esp8266.read()-48)*10; // get first number i.e. if the pin 13 then the 1st number is 1, then multiply to get 10
     pinNumber += (esp8266.read()-48); // get second number, i.e. if the pin number is 13 then the 2nd number is 3, then add to the first number
     
     digitalWrite(pinNumber, !digitalRead(pinNumber)); // toggle pin    
     
     // make close command
     String closeCommand = "AT+CIPCLOSE="; 
     closeCommand+=connectionId; // append connection id
     closeCommand+="\r\n";
     
     sendData(closeCommand,1000,DEBUG); // close connection
    }
  }
}
 
/*
* Name: sendData

* Returns: The response from the esp8266 (if there is a reponse)
*/
String sendData(String command, const int timeout, boolean debug)
{
    String response = "";
    
    Serial.println(esp8266.print(command)); // send the read character to the esp8266
    
    long int time = millis();
    while( (time+timeout) > millis())
    {
      
      while(esp8266.available())
      {
        Serial.print("Coming");
        
        // The esp has data so display its output to the serial window 
        char c = esp8266.read(); // read the next character.
        response+=c;
      }  
    }


    
    if(debug)
    {
      Serial.print(response);
    }
    
    return response;
}

the problem is i am not getting any output from esp module but arduino is transmitting the data. power supply for esp is given by 3.3v regulator (LD3.3)feeding 12v from arduino power supply adapter to regulator input . TX esp to rx arduino arduino tx to esp rx by voltage divider (R1=1k and R2=1.8k) esp gnd to arduino gnd chpd and esp vin are 3.3v from regulator Can anyone tell me where the problem is ?
