NRF24L01 only receiving zeros I'm attempting to transmit very simple data across some NRF24l01 modules for testing purposes, and I've been following a YouTube guide.

Here is my code:

Trasmitter:

#include "RF24.h"
#include &lt;SPI.h&gt;

RF24 Radio (7, 8);
byte address[][6] = {"0"};
struct package{
   int on = 1;
};

typedef struct package Package;
Package data;

void setup() {
  Serial.begin(9600);
  delay(1000);
  Radio.begin();
  Radio.setChannel(118);
  Radio.setPALevel(RF24_PA_LOW);
  Radio.setDataRate(RF24_250KBPS);
  Radio.openWritingPipe(address[0]);
  delay(1000);
}

void loop() {
  Radio.write(&amp;data, sizeof(data));

  Serial.println("Data sent:");
  Serial.println(data.on);
  delay(1000);
  }
}


Receiver:

 #include "RF24.h"
 #include &lt;SPI.h&gt;

 RF24 Radio (7, 8);
 byte address[][6] = {"0"};
 struct package{
    int on = 1;
 };

 typedef struct package Package;
 Package data;

 void setup() {
   Serial.begin(9600);
   pinMode(2, OUTPUT);
   delay(1000);
   Radio.begin();
   Radio.setChannel(118);
   Radio.setPALevel(RF24_PA_LOW);
   Radio.setDataRate(RF24_250KBPS);
   Radio.openReadingPipe(1, address[0]);
   Radio.startListening();
   delay(1000);
 }

 void loop() {
   while(Radio.available()){
     Radio.read(&amp;data, sizeof(data));
     if(data.on == 1){
       digitalWrite(2, HIGH);
     }
     else if(data.on == 0){
       digitalWrite(2, HIGH);
     }
     else{
       digitalWrite(2, LOW);
     }
     Serial.println(data.on);
   }
   while(!Radio.available()){
     Serial.println("Error");
   }
   delay(1000);
 }


When I run the code on each respective unit, I receive only zeros on the receiver. Since I don't see where data.on could get set to zero in my code, I'm assuming there is a communication issue somehow between the two modules, even though Radio.available() is functioning properly.

Am I missing something obvious?

The issue turned out to be that the SPI pins on the MEGA are assigned differently than the UNO, and the code was actually working the whole time. I cant thank you enough for helping me, even if it turned out to be in vain.
