Problem with MPU6050 + NRF24l01 + Processing

Hi, I am a new member of this forum. I write here because I have a small problem with my project; in this days I am trying to send the MPU 6050 datas with the transceiver nRF24l01 to the serial port of my pc, where elaborate it as in this link: How to: MPU6050 DMP Teapot Demo for Arduino - YouTube. That is the code of trasmitter:

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#define CE_PIN 9
#define CSN_PIN 53

#include "I2Cdev.h"
#include "MPU6050_6Axis_MotionApps20.h"
//#include "MPU6050.h" // not necessary if using MotionApps include file
#if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE
#include "Wire.h"
#endif


#define OUTPUT_TEAPOT



#define INTERRUPT_PIN 2  // use pin 2 on Arduino Uno & most boards
#define LED_PIN 13 // (Arduino is 13, Teensy is 11, Teensy++ is 6)
bool blinkState = false;

// MPU control/status vars
bool dmpReady = false;  // set true if DMP init was successful
uint8_t mpuIntStatus;   // holds actual interrupt status byte from MPU
uint8_t devStatus;      // return status after each device operation (0 = success, !0 = error)
uint16_t packetSize;    // expected DMP packet size (default is 42 bytes)
uint16_t fifoCount;     // count of all bytes currently in FIFO
uint8_t fifoBuffer[64]; // FIFO storage buffer
float Z;


typedef struct{
  .
  .   <---- not important part
  .
C_t dati2; 

// orientation/motion vars
Quaternion q;           
VectorInt16 aa;        
VectorInt16 aaReal;  
VectorInt16 aaWorld;    
VectorFloat gravity;    
float euler[3];        
float ypr[3];           

uint8_t teapotPacket[14] = { '

The problem arises when I include the function radio.write, blocking code at the comand : Serial.println(F("DMP ready! Waiting for first interrupt..."));

Code start if I take off the 3 function "radio.write", obviously without sending nothing.
If someone identify the problem I would be very grateful.
Thanks.
