NRF24L01+ module Error sending Hello world.

Hello i found a site that send a Hello world from one arduino to another arduino using the Nrf24l01+ modules i have used them before sending a ping but i wanted to send some text and receive it on the other end so this website Connecting and programming nRF24L01 with Arduino and other boards – Starter Kit i went to it and got

Transmit:
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>

RF24 radio(7, 8);

const byte rxAddr[6] = "00001";

void setup()
{
  radio.begin();
  radio.setRetries(15, 15);
  radio.openWritingPipe(rxAddr);
  
  radio.stopListening();
}

void loop()
{
  const char text[] = "Hello World";
  radio.write(&text, sizeof(text));
  
  delay(1000);
}

and Receiving:

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>

RF24 radio(7, 8);

const byte rxAddr[6] = "00001";

void setup()
{
  while (!Serial);
  Serial.begin(9600);
  
  radio.begin();
  radio.openReadingPipe(0, rxAddr);
  
  radio.startListening();
}

void loop()
{
  if (radio.available())
  {
    char text[32] = {0};
    radio.read(&text, sizeof(text));
    
    Serial.println(text);
  }
}

When i go to the transmitting side this error comes when i try to compile the sketch

sketch_feb17d.ino: In function 'void setup()':
sketch_feb17d:13: error: invalid conversion from 'const byte*' to 'uint64_t'
sketch_feb17d:13: error: initializing argument 1 of 'void RF24::openWritingPipe(uint64_t)'

i have never seen before can someone please help me out? thank you.

From the documentation:

Addresses are 40-bit hex values, e.g.:

   openWritingPipe(0xF0F0F0F0F0);

You're trying to pass it a string when it wants a 64 bit unsigned int instead.

So what means it needs a longer address that looks like a mac address?

Okay i think i found my problem wrong Library i was using manaicbug library and in the website says use TMr library. so i did and it works. but there is one slight problem when sending the hello world transmitting it to the receiver side is a bad delay. there is no delay on the receiver side but on the transmitting side there is a delay of 1000 one second and comes in very slow. i try to change that to 100 ms didn't make no difference. So i comment out the delay and it went faster but instead of getting one Hello world at a time i get 3 or 4 at a time so i need to uncomment out the delay again. my Question is should i make the delay smaller like 10 ms ? or more or lower? to make it go faster if needed?
