SoftwareSerial esp8266(2,3); 

// the TX pin of esp8266 is connected to pin 3 of 
// arduino uno and RX pin is connected to 2    
// we need to pass baud rate to begin function

void setup()
{
  Serial.begin(115200);
  esp8266.begin(???); // what should i do in order to make it work?
}

    Simplest to just re-flash the AT firmware. Follow one of the many thousands of tutorials, or find all the answers here telling you how. – Majenko Aug 24 '17 at 9:20
  • I tried to flash, everywhere it is asking for baud rate to communicate to esp8266,i tried 9600 which is configured for my arduino, it doesnt work. – Rajat Aug 27 '17 at 12:17
  • You need the bootloader baud rate. Try 57600. – Majenko Aug 27 '17 at 12:18
  • Hi Majenko, i tried all the possible standard baud rates(including 57600), did not work :/ – Rajat Aug 30 '17 at 18:23
  • I couldn't find a solution, So, bought new esp8266 and worked with it default baudrate (115200). – Rajat Sep 9 '17 at 11:16
