puts Arduino outputs garbage values aton serial monitor with esp8266ESP8266

I have connected my arduinoArduino with esp8266an ESP8266.

When I check esp8266the ESP8266, by manually entering commands at serial monitor i, I get correct results.

ButHowever, when I run this program

#include<SoftwareSerial.h>

SoftwareSerial esp8266(2,3);

void setup() {
  Serial.setTimeout(5000);
  Serial.begin(115200);
  esp8266.begin(115200);
  delay(1000);
}

void loop() {
  delay(2000);
  String command="AT";
  
  esp8266.println(command);
  if(esp8266.available())
  {
    while(esp8266.available())
    {
      char c=esp8266.read();
      Serial.write(c);          
    }
  }
}

I get garbage values where sometimes it has OK inbetween it.an OK in between the output:

" Received: "ÁT OK " Received: "AÔ ÏË " Received: "AÔ OK " Received: "ÁT ÏË " Received: "ÁT OË " Received: "ÁÔ OK " Received: "Á¬ OK " Received: "ÁT OË "

Could someone help me?
