Arduino nano with nRF24L0... Can anyone hepls?

Hey,

I have two arduiono nano boards and two nRF24L0 RF-links. I have tried many cases but I haven’t got it works… Does anyone gives me SIMPLE code how to send STRING over RF…?? Thank you for your help.

How have you wired them up? What code are you using now?

hei

This is Nrf24 examle and this is working… but now I want to send string…

#include <SPI.h>
#include <Mirf.h>
#include <nRF24L01.h>
#include <MirfHardwareSpiDriver.h>

void setup(){
  Serial.begin(9600);
  /*
   * Setup pins / SPI.
   */
   
  /* To change CE / CSN Pins:
   * 
   * Mirf.csnPin = 9;
   * Mirf.cePin = 7;
   */
  /*
  Mirf.cePin = 7;
  Mirf.csnPin = 8;
  */
  Mirf.spi = &MirfHardwareSpi;
  Mirf.init();
  
  /*
   * Configure reciving address.
   */
   
  Mirf.setRADDR((byte *)"clie1");
  
  /*
   * Set the payload length to sizeof(unsigned long) the
   * return type of millis().
   *
   * NB: payload on client and server must be the same.
   */
   
  Mirf.payload = sizeof(unsigned long);
  
  /*
   * Write channel and payload config then power up reciver.
   */
   
  /*
   * To change channel:
   * 
   * Mirf.channel = 10;
   *
   * NB: Make sure channel is legal in your area.
   */
   
  Mirf.config();
  
  Serial.println("Beginning ... "); 
}

void loop(){
  unsigned long time = millis();
  
  Mirf.setTADDR((byte *)"serv1");
  
  Mirf.send((byte *)&time);
  
  while(Mirf.isSending()){
  }
  Serial.println("Finished sending");
  delay(10);
  while(!Mirf.dataReady()){
    //Serial.println("Waiting");
    if ( ( millis() - time ) > 1000 ) {
      Serial.println("Timeout on response from server!");
      return;
    }
  }

  Mirf.getData((byte *) &time);
  
  Serial.print("Ping: ");
  Serial.println((millis() - time));
  
  delay(1000);
}

I soved this question... =)
