Hex printing

Hardware Arduino Due
1

I use two Arduino DUE in i2c . The master reads the data from the slave. The slave sends the data (0XBB),I have attached the programs and the output ,I must receive 0XBB on master side ,but i donot get it

Master code

#include <Wire.h>

void setup() {
  // put your setup code here, to run once:
Wire.begin();        // join i2c bus (address optional for master)
Serial.begin(9600);  // start serial for output

}
void PrintHex8(int num,int precision)
{
  char tmp[16];
  char format[128];
  sprintf(format, "0x%%.%dX",precision);

  sprintf(tmp,format,num);
  Serial.println(tmp);
  }

void loop() {
  // put your main code here, to run repeatedly:
Wire.requestFrom(0x03, 8);   

  while(Wire.available())   
  { 
   Serial.println("Receiving");

   uint8_t i  = Wire.read();
    
    PrintHex8(i,1);
   
    delay(500);
}

}

Slave code:

#include <Wire.h>

void setup()
{
  Wire.begin(0x03);                
  Wire.onRequest(requestEvent); // register event
}

void loop()
{
  delay(100);
}

// function that executes whenever data is requested by master
// this function is registered as an event, see setup()
void requestEvent()
{
  Wire.write("0xBB ");
}

Output:
0x48
