RF24 tranceivers: trouble with two way communication

I am using RF24 modules with my two Arduinos Leonardo with the RF24 library. My goal is to be able to press a button on the first Arduino which will light up an LED on the second Arduino, and be able to press a button on the second Arduino to light up an LED on the first Arduino. I was easily able to figure this out as a one-way transmission with the first Arduino only transmitting and the second only receiving, but I am unable to make it a two-way transmission, where each Arduino can transmit and receive at the same time.

This is my code so far:

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

int msg[1];
RF24 radio(9,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
const uint64_t pipe2 = 0xF0F0F0F0AA;
void setup(void){
  Serial.begin(57600);
  pinMode(A0, INPUT);
  radio.begin();
  radio.openWritingPipe(pipe);
  radio.openReadingPipe(1,pipe2);
}

void loop(void){
  int charToSend[1];
  charToSend[0] = digitalRead(A0);
  if (!radio.write(charToSend,1)) {Serial.println('didn\'t send');}
  radio.startListening();
  if (radio.available()){
    bool done = false;  
    done = radio.read(msg, 1); 
    Serial.println(msg[0]);
    digitalWrite(13, msg[0]);
  }
  radio.stopListening();
  radio.powerDown(); 
  delay(10);
  radio.powerUp();
}

But the radio.write() is returning false and therefore not sending.
