esp8266

Hello
please I have a problem in the programming code of the wifi ESP8266 .i hope someone help me on my project.

#include <SoftwareSerial.h>

SoftwareSerial wifiSerial(2, 3); // RX, TX for ESP8266

bool DEBUG = true; //show more logs
int responseTime = 10; //communication timeout

void setup()
{
pinMode(13,OUTPUT); //set build in led as output
// Open serial communications and wait for port to open esp8266:
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
wifiSerial.begin(115200);
while (!wifiSerial) {
; // wait for serial port to connect. Needed for Leonardo only
}
sendToWifi(“AT+CWMODE=2”,responseTime,DEBUG); // configure as access point
sendToWifi(“AT+CIFSR”,responseTime,DEBUG); // get ip address
sendToWifi(“AT+CIPMUX=1”,responseTime,DEBUG); // configure for multiple connections
sendToWifi(“AT+CIPSERVER=1,80”,responseTime,DEBUG); // turn on server on port 80

sendToUno(“Wifi connection is running!”,responseTime,DEBUG);

}

void loop()
{
if(Serial.available()>0){
String message = readSerialMessage();
if(find(message,“debugEsp8266:”)){
String result = sendToWifi(message.substring(13,message.length()),responseTime,DEBUG);
if(find(result,“OK”))
sendData("\nOK");
else
sendData("\nEr");
}
}
if(wifiSerial.available()>0){

String message = readWifiSerialMessage();

if(find(message,“esp8266:”)){
String result = sendToWifi(message.substring(8,message.length()),responseTime,DEBUG);
if(find(result,“OK”))
sendData("\n"+result);
else
sendData("\nErrRead"); //At command ERROR CODE for Failed Executing statement
}else
if(find(message,“HELLO”)){ //receives HELLO from wifi
sendData("\nHI!"); //arduino says HI
}else if(find(message,“LEDON”)){
//sending ph level:
digitalWrite(13,HIGH);
}else if(find(message,“LEDOFF”)){
//sending ph level:
digitalWrite(13,LOW);
}
else{
sendData("\nErrRead"); //Command ERROR CODE for UNABLE TO READ
}
}
delay(responseTime);
}

please I have a problem in the programming code of the wifi ESP8266

But you haven't told us what it is.
