Signal problems with long-range Nordic nRF24L01+PA+LNA 2.4GHz RF module

Hello , I am trying to create a one way controller for a project and the (nRF24L01+PA+LNA) wireless modules will not connect to each other and I have tried all the suggestions I could find but nothing will even give me a sign of connection. Here is the code that I am using.

This is the Controller (Transmitter) Code. It is run by and Arduino Uno R3
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
RF24 radio(9, 10); // CE, CSN
const byte address[6] = "00001";
void setup() {
Serial.begin(9600);
radio.begin();
radio.openWritingPipe(address);
radio.setPALevel(RF24_PA_MIN);
radio.stopListening();
}
void loop() {
const char text[] = "1111";
radio.write(&text, sizeof(text));
Serial.println(text);
delay(1000);
}

This is the Reciever code. It is run by an Arduino Mega2560.
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
RF24 radio(49, 48); // CE, CSN
const byte address[6] = "00001";
void setup() {
Serial.begin(9600);
radio.begin();
radio.openReadingPipe(1, address);
radio.setPALevel(RF24_PA_MIN);
radio.startListening();
digitalWrite(22, HIGH);
delay(50);
digitalWrite(22, LOW);
delay(50);
}
void loop() {
if (radio.available()) {
char text[32] = "";
radio.read(&text, sizeof(text));
Serial.println(text);
if(text=="1111"){
Serial.println("Done");
digitalWrite(22, HIGH);
}
else{
digitalWrite(22, LOW);
}
}
}

Thank you very much. If you have any suggestions please let me know. I very much admire your knowledge of coding and electronics and I strive to be an engineer one day.

I have suggested to the Moderator to move your Post to its own Thread.

Have a look at this Simple nRF24L01+ Tutorial.

Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.

The examples are as simple as I could make them and they have worked for other Forum members. If you get stuck it will be easier to help with code that I am familiar with. Start by getting the first example to work

The high power nRF24 needs more current than an Arduino 3.3v pin can provide. Try using a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND.

If the high power nRF24 is too close to its mate it can overwhelm it. Try it at a distance of 2 or 3 metres (or more).
