Question

我正在尝试通过VRF槽NRF24l01模块在Arduino和RaspberryPi 3模型之间建立通信。

我遵循了本教程： http://invent.module143.com/daskal_tutorial/raspberry-pi-3-wireless-pi-to-arduino-communication-with-nrf24l01/

    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()

    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 &gt;= 32 and n &lt;= 126):
                string += chr(n)
        print("Out received message decodes to: {}".format(string))

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

    // ce, csn pins
    RF24 radio(9, 10);

    void setup(void){
    radio.begin();
    radio.setPALevel(RF24_PA_MAX);
    radio.setChannel(0x76);
    radio.openWritingPipe(0xF0F0F0F0E1LL);
    radio.enableDynamicPayloads();
    radio.powerUp();

    }

    void loop(void){
        const char text[] = "Hello World is awesome";
        radio.write(&text, sizeof(text));
        delay(1000);

    }

RPi无法读取arduino发送的数据。在终端中，它使用与arduino发送的内容无关的整数来打印数组。不论是否插入arduino，RPi都能打印出相同的结果，因此很明显根本没有任何连接。

RPI和ARDUINO之间的NRF24L01传输不起作用
