nRF24L01+PA+LNA not working with Uno and Mega

I only have one USB cable, so I can't connect both Arduino boards to my computer.

Here is my updated transmitter code:

#include <printf.h>
#include <RF24.h>

RF24 radio(9, 10);
const byte address[6] = "00001";

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  printf_begin();
  radio.begin();
  radio.openWritingPipe(address);
  radio.setPALevel(RF24_PA_MIN);
  radio.stopListening();
  radio.printDetails();
}

void loop() {
  // put your main code here, to run repeatedly:
  const char text[] = "Hello World";
  radio.write(&text, sizeof(text));
  delay(1000);
}

Meanwhile, here is my updated receiver code:

#include <printf.h>
#include <RF24.h>

RF24 radio(49, 53);
const byte address[6] = "00001";

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  printf_begin();
  radio.begin();
  radio.openReadingPipe(0, address);
  radio.setPALevel(RF24_PA_MIN);
  radio.startListening();
  radio.printDetails();
}

void loop() {
  // put your main code here, to run repeatedly:
  if (radio.available()) {
    char text[32] = "";
    radio.read(&text, sizeof(text));
    Serial.println(text);
  }
}
