请教一个arduino连接nrf24l01接受数据 的问题！！困扰很久了！

#include "SPI.h"
#include "Mirf.h"
#include "nRF24L01.h"
#include "MirfHardwareSpiDriver.h"
int S1;
int S2;
int S3;
void setup(){
Mirf.spi = &MirfHardwareSpi;
Mirf.init();
Mirf.setTADDR((byte *)"serv1");
Mirf.payload = sizeof(int);
Mirf.config();
}

void loop()
{
S1=analogRead(A0);
S2=analogRead(A1);
S3=analogRead(A2);
Mirf.send((byte *)&S1);
while(Mirf.isSending()){}
Mirf.send((byte *)&S2);
while(Mirf.isSending()){}
Mirf.send((byte *)&S3);
while(Mirf.isSending()){}
delay(2000);
}
