Multimaster system code on I2C for Arduino works fine

Hi...!!!
Following codes works fine on I2C for both way communication. Using this multimaster system can be understood on I2C.

//Sending command 4 bytes command to Payload and Receiving 60 bytes of data

#include <Wire.h>
int command[4] = {0x50, 0x46, 0x00, 0x00};
int mm = 0;
int count=0;
void setup()
{
  Wire.begin(6);                
  Wire.onReceive(receiveEvent); 
  Serial.begin(9600);          
}

void loop()
{
  
  
  delay(20);
  Wire.beginTransmission(0x05);
  Wire.write(command[mm]);
  delay(70);
  mm++;
  if(mm==4)
  {mm = 0;}
  Wire.endTransmission();
  
}

void receiveEvent(int howMany)
{
  
  while(1 < Wire.available()) 
  { }
  int x = Wire.read();
  count++;  if(count == 60){count = 0; Serial.println(' ');}
  Serial.print(x, HEX); 



}

//Output

//Payload Camera Receiving 4 bytes of command and sending 60 bytes of data

#include <Wire.h>
int mm=0;
int outgoingByte[60] = {0xFF,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0B,0xff,0x0c,0x02,0x0d,

{int rtrn;


//For payload camera
 Wire.beginTransmission(6);

  Wire.write(outgoingByte[mm]);
  mm++;
  if(mm==60)
  {
  mm = 0;
  }
  delay(100); 
 rtrn = Wire.endTransmission();
 delay(100);}
 
 void receiveEvent(int howMany)
 {while(1 <Wire.available())
 {}
 int ch = Wire.read();
 Serial.println(ch, HEX);}

//Output

This code is working fine for my I2C implementation.
