Transmit String with nRF24L01+ modules and Mirf Library

hello everybody,
i'm asking project. want send string first arduino board second arduino board using nrf24l01 modules , mirf library. don't know how convert array of bytes caught receiver string, , how print it.

this program on first (sender) :

code: [select]


#include <spi.h>
#include <mirf.h>
#include <nrf24l01.h>
#include <mirfhardwarespidriver.h>

string data;

void setup(){
  serial.begin(9600);
  mirf.spi = &mirfhardwarespi;
  mirf.init();
  mirf.setraddr((byte *)"pcard");
  mirf.payload = sizeof(string);
  mirf.config();
  serial.println("configuration terminé");
  mirf.settaddr((byte *)"drone");
  serial.println("configuration terminé");
}

void loop(){
 
   
  if(serial.available()>0){
    data = serial.readstring();
    serial.println("bien recu : "+ data);
    mirf.send((byte *) &data);
   
    while(mirf.issending()){
    }
    serial.println("finished sending");
    }
}


this code on receiver :

code: [select]


#include <spi.h>
#include <mirf.h>
#include <nrf24l01.h>
#include <mirfhardwarespidriver.h>




void setup(){
  serial.begin(9600);
  mirf.spi = &mirfhardwarespi;
  mirf.init();
  mirf.setraddr((byte *)"drone");
  mirf.payload = sizeof(string);
  mirf.config();
  serial.println("configuration terminé");
 
}

void loop(){
  string data="";

 
  if(mirf.dataready()){   
    mirf.getdata((byte *) &data);
    serial.println(data);
  }
}

thanks help 

if need in array of bytes transmitting on transceiver, why bother strings in first place? use char arrays (also known strings)
