代码不会发送我想要的权衡

我试图制作一个有关NRF24L01 的项目，并将其连接到Arduino和Raspberry Pi。然后，我写了代码。它没有回应。因此，我从一个网站上拿走了它，它起作用了。但是，它是一次发送消息。但是那里的代码是为了持续发送的。因此，我决定在Arduino代码中放置一条串行线，以弄清楚我在做错了什么。正如预期的那样，串行线一次打印了" A"。但是我将其放在一个循环中！所以，你们对我做错了什么有想法吗？

Arduino代码如下：

//These libraries are fully downloaded.
#include<SPI.h>
#include<RF24.h>
// ce, csn pins, connected properly.
RF24 radio(9, 10) ;
//Here, I set up the stuff needed for the Transciever.
void setup(void){
  radio.begin() ;
  radio.setPALevel(RF24_PA_MAX) ;
  radio.setChannel(0x76) ;
  radio.openWritingPipe(0xF0F0F0F0E1LL) ;
  radio.enableDynamicPayloads() ;
  radio.powerUp() ;
  Serial.begin(9600);
}
void loop(void){
  const char text[] = "Hello World!" ;
  Serial.println("A");
  radio.write(&text, sizeof(text)) ;
  delay(1000) ;
  //s
 }

和RPI3代码如下所示：

#The libraries are downloaded.
import RPi.GPIO as GPIO
from lib_nrf24 import NRF24
import time
import spidev
GPIO.setmode(GPIO.BCM)
pipes = [[0xE8, 0xE8, 0xF0, 0xF0, 0xE1], [0xF0, 0xF0, 0xF0, 0xF0, 0xE1]]
radio = NRF24(GPIO, spidev.SpiDev())
radio.begin(0, 17)
radio.setPayloadSize(32)
radio.setChannel(0x76)
radio.setDataRate(NRF24.BR_1MBPS)
radio.setPALevel(NRF24.PA_MIN)
radio.setAutoAck(True)
radio.enableDynamicPayloads()
radio.enableAckPayload()
radio.openReadingPipe(1, pipes[1])
radio.printDetails()
radio.startListening()
try:
 while(1):
     # ackPL = [1]
     while not radio.available(0):
         time.sleep(1 / 100)
     receivedMessage = []
     radio.read(receivedMessage, radio.getDynamicPayloadSize())
     print("Received: {}".format(receivedMessage))
     print("Translating the receivedMessage into unicode characters")
     string = ""
     for n in receivedMessage:
         # Decode into standard unicode set
         if (n >= 32 and n <= 126):
             string += chr(n)
     print("Out received message decodes to: {}".format(string))
except KeyboardInterrupt:
    GPIO.cleanup() 

那么，您在我的代码中看到了任何问题吗？我真的需要解决这个问题。这是我从那里获得的链接：https://www.google.com.tr/url?sa = t& amp; rct=j& q =＆q =＆amp；vpcdxo7hahukyaykhzp9dq8qfjakegqiaxab＆amp; amp; url = http％3A％2f％2f thezanshow.com％2felectrectronics tutorials tutorials％2fraspberry pi everperry-pi％2ftuter-pi％2ftutorial-2ftutorial-2ftutorial-34-35＆amp; usg = usg = aofvawawawawawawawawawaw26oekcm> cm> cm> cm> cm> cm> cm> cm> cm> cm> cm> cm> cm>
