NRF24- Why doesnt my receiver or transmitter work?

Transmitter:

//on MEGA
#include <SPI.h>
#include <RF24.h>
#include <nRF24L01.h>
#include <printf.h>
#include <RF24_config.h>
                    
#define Rstick_y    A2  
                     
#define CE_PIN      8
#define CSN_PIN     53
RF24 radio(CE_PIN, CSN_PIN); 
byte addresses[][6] = {"1Node"};
   
struct positionData
{                      
  byte Raxis_y;        
};
positionData data;                                   

void setup()
{
  Serial.begin(115200);
  Serial.println("Starting");
  radio.begin();   
  radio.setPALevel(RF24_PA_LOW);            
  radio.setDataRate(RF24_250KBPS);
  radio.openWritingPipe(addresses[0]);           
}
void loop()
{
  Serial.print("BEGIN");
  data.Raxis_y = analogRead(Rstick_y);              //read the joystick
  radio.stopListening();                            //is this part needed for transmitter?
  radio.write( &data, sizeof(unsigned long) );           
  Serial.print("    Ryaxis: ");          Serial.println(data.Raxis_y);
}

the "data.Raxis_y" reads values from 0 to 255. why isnt it reading values from 0 to 1023 like a joystick?

Reciever

//reciever will have the motors
#include <SPI.h>
#include <RF24.h>
#include <nRF24L01.h>
#include <printf.h>
#include <RF24_config.h>

#define CE_PIN   7
#define CSN_PIN  8
RF24 radio(CE_PIN, CSN_PIN);  
byte addresses[][6] = {"1Node"};      

struct positionData{  
  byte Raxis_y;          
};
positionData data;

void setup(){
  Serial.println("Starting");             
  Serial.begin(115200);
  radio.begin();                                    //Link The Radio
  radio.setPALevel(RF24_PA_LOW);
  radio.setDataRate(RF24_250KBPS);
  radio.openReadingPipe(1, addresses[0]);                  
  radio.startListening();      
}


void loop() 
{
  if ( radio.available() )
  {                                    
    while (radio.available()){
      radio.read( &data, sizeof(unsigned long) );              
    }
    int right_y = data.Raxis_y;
    Serial.print("    RightJoystick: ");
    Serial.print(right_y);                       
  }
  else{
    Serial.println("LOST"); 
  } 
}

it keeps print LOST, what am i doing wrong?

As far as I can see you now have this and two other Threads (here and here) for this single project.

It is much easier to help if you just have a single Thread for a single project.

You can click "Report to Moderator" and ask for them to be merged.

I don't plan to read all three all the time to try to keep myself up to date.
