Nrf24L01 + Arduino Mega2560 send joystick data - arduino

Question

I'm trying to send the x and y values of a joystick between two arduino mega 2560 with an nrf24l01. So far I have a transmitter and reciever code but I get wrong values on the reciever.
Transmitter:
#include <SPI.h>
#include <RF24.h>
RF24 radio(7,8);
byte addresses[][6] = {"0x115331","0x222331"};
typedef struct{
int X;
int Y;
int K;
}
Values;
Values v;
void setup() {
pinMode(10, INPUT);
Serial.begin(115200);
radio.begin();
radio.setPALevel(RF24_PA_LOW);
radio.setChannel(108);
radio.setPayloadSize(32);
radio.openWritingPipe(addresses[1]);
radio.openReadingPipe(1,addresses[0]);
}
void loop() {
radio.stopListening();
v.X = analogRead(A0);
v.Y = analogRead(A1);
v.K = digitalRead(10);
Serial.print("X = ");
Serial.println(v.X);
Serial.print("Y = ");
Serial.println(v.Y);
Serial.print("Button status: ");
if (v.K == HIGH)
{
Serial.println("pressed");
}
else
{
Serial.println("not pressed");
}
radio.write(&v,sizeof(v));
delay(500);
}
Reciever:
#include <SPI.h>
#include <RF24.h>
RF24 radio(7,8);
byte addresses[][6] = {"0x115331","0x222331"};
typedef struct{
int X;
int Y;
int K;
}
Values;
Values v;
void setup() {
Serial.begin(115200);
radio.begin();
radio.setPALevel(RF24_PA_LOW);
radio.openWritingPipe(addresses[0]);
radio.openReadingPipe(1,addresses[1]);
radio.setChannel(108);
radio.setPayloadSize(32);
radio.startListening();
}
void loop() {
radio.startListening();
if ( radio.available() )
{
while(radio.available())
{
radio.read(&v, sizeof(v));
}
}
radio.stopListening();
Serial.println(v.X);
Serial.println(v.Y);
Serial.println(v.K);
delay(1000);
}
I'm using the pin configuration from this website: https://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo
