Serial printing things using the F() macro outputs gibberish

I'm trying to run this example scketch from the RF24 library, but it outputs gibberish in the terminal:

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

/****************** User Config ***************************/
/***      Set this radio as radio number 0 or 1         ***/
bool radioNumber = 0;

/* Hardware configuration: Set up nRF24L01 radio on SPI bus plus pins 7 & 8 */
RF24 radio(1,2);
/**********************************************************/

byte addresses[][6] = {"1Node","2Node"};

// Used to control whether this node is sending or receiving
bool role = 0;

void setup() {
  Serial.begin(115200);
  Serial.println(F("RF24/examples/GettingStarted"));
  Serial.println(F("*** PRESS 'T' to begin transmitting to the other node"));
  
  radio.begin();

  // Set the PA Level low to prevent power supply related issues since this is a
 // getting_started sketch, and the likelihood of close proximity of the devices. RF24_PA_MAX is default.
  radio.setPALevel(RF24_PA_LOW);
  
  // Open a writing and reading pipe on each radio, with opposite addresses
  if(radioNumber){
    radio.openWritingPipe(addresses[1]);
    radio.openReadingPipe(1,addresses[0]);
  }else{
    radio.openWritingPipe(addresses[0]);
    radio.openReadingPipe(1,addresses[1]);
  }
  
  // Start the radio listening for data
  radio.startListening();
}

If I don't use the F() macro it works properly. I've read that it could be the microcontroller running out of memory, but it is not, here is the log:
Sketch uses 5,706 bytes (17%) of program storage space. Maximum is 32,256 bytes.
Global variables use 565 bytes (27%) of dynamic memory, leaving 1,483 bytes for local variables. Maximum is 2,048 bytes.

I also tried to test the F() macro using a simple scketch and it works well, the problem seems to happen only with this library.
Any thoughts? I really don't know what else to do.

/* Hardware configuration: Set up nRF24L01 radio on SPI bus plus pins 7 & 8 */
RF24 radio(1,2);

Looks like you are using Pin 1 for part of the nRF24L01 interface. Unfortunately that is one of the Serial I/O pins. DON'T use Pin 0 or Pin 1 for data if you want to use Serial.

Thanks, I changed the pins to 2 and 3 and the serial is working.
