nRF24 network, issue with void function

Projects Programming

Greetings
I'm working on a devices communicating in nRF24 network and at this moment I'm trying to send informations both ways but i have a issue with one void function called SendToMaster in slaves program (I have 3 slaves with mostly identical code).

When i try to compile the code I am faced with this error:
\Slave_2.ino: In function 'void SendToMaster(byte)':
Slave_2:55:44: error: invalid types 'const uint64_t {aka const long long unsigned int}[int]' for array subscript
exit status 1
invalid types 'const uint64_t {aka const long long unsigned int}[int]' for array subscript

Here's the program:

#include <RF24Network.h>
#include <RF24Network_config.h>
#include <nRF24L01.h>
#include <RF24.h>
#include <RF24_config.h>
#include <SPI.h>

RF24 radio(10, 9); //nRF24L01 pins (CE, CSN)
const uint64_t rAddress = 0xB00B1E50A4LL;
const uint64_t wAddress = 0xB00B1E50C3LL;
int LED = 0; // LED state
bool Hit = 0; //sensor state


void setup() 
{
  Serial.begin(57600);
  Serial.println("Listening");
  radio.begin();
  radio.openReadingPipe(1, rAddress);
  radio.startListening();
  pinMode(3, OUTPUT); //LED green
  pinMode(4, OUTPUT); //LED red
  pinMode(5, OUTPUT); //LED blue
  pinMode(8, INPUT);  //vibration sensor
}

void loop() 
{
  byte pipe = 0;
  while (radio.available(&pipe))
  {
    radio.read(&LED, sizeof(LED));
    if (LED==1)
    {
      Serial.println("Light");
      digitalWrite(3, HIGH);
      unsigned long startTimer = millis();
      SendToMaster(pipe);
    }
  
    if (LED==0)
    {
      Serial.println("Darkness");
      digitalWrite(3, LOW);
      SendToMaster(pipe);
    }
  }    
}

void SendToMaster(byte xAddress)
{
  radio.stopListening();
  radio.openWritingPipe(wAddress[xAddress-1]);
  radio.write(&LED, sizeof(LED));
  Serial.println("Send back");
  radio.startListening();
}

I'd be grateful for help with that issue and an explanation how to operate with the variable types in void, bool, int etc. functions

You try to access this variable as an array.

Thank you, you're right.
Ahhh, I still can't remember such a simple rules. How can I close this topic?

Why do you use the deprecated call with an uint64_t at all?

I hate all the deprecated messages on compile, they are hiding other warnings.

For this time it's just easy to use cause I was inspired by some tutorial on YT. I've tried codes from the examples and just leaved some parts of them to the new codes. I'm an total newbie so I don't want to complicate my work.

Change that.
