【问题描述】：

我有两个 Arduino Unos、两个液晶显示器和 Xbee s2。我将两个 xbee s2 模块连接到每个 arduino uno。我努力搜索了这个实现并尝试了它。但是，它没有用。感谢您的帮助。

配置：AP=2 协调器 API 和路由器 API

发送者：路由器

 #include <XBee.h>
       #include <SoftwareSerial.h

#include <LiquidCrystal.h>
#define LED 13
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
SoftwareSerial xSerial(3,4);
XBee xbee=XBee();
ZBTxStatusResponse txStatus = ZBTxStatusResponse();

void setup(){
  //Serial.begin(9600);
  xSerial.begin(9600);
  xbee.setSerial(xSerial);
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("hello, Gang!");
  //Serial.println("xbee start");
  pinMode(LED, OUTPUT);
  digitalWrite(LED, HIGH);
  delay(3000);
}

void loop(){
  ZBTxRequest zbTx;
  uint8_t payload[]={'H', 'E', 'Y', '\0'};
  XBeeAddress64 address=XBeeAddress64(0x13a200, 0x40b450f4);
  zbTx=ZBTxRequest(address, payload, sizeof(payload));
  xbee.send(zbTx);
   if (xbee.readPacket(500)) {              
    if (xbee.getResponse().getApiId() == ZB_TX_STATUS_RESPONSE) {
      xbee.getResponse().getZBTxStatusResponse(txStatus);
      // get the delivery status, the fifth byte
      if (txStatus.getDeliveryStatus() == SUCCESS) {
        lcd.setCursor(0,1);
        lcd.print("Success");
      } else {
        // the remote XBee did not receive our packet. is it powered on?
      }
    }
  } else if (xbee.getResponse().isError()) {
    //nss.print("Error reading packet.  Error code: ");  
    //nss.println(xbee.getResponse().getErrorCode());
  } else {
    // local XBee did not provide a timely TX Status Response -- should not happen
  }

  delay(1000);
}

#include <SoftwareSerial.h>
#include <XBee.h>

#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

SoftwareSerial xSerial(3,4);

XBee xbee=XBee();
XBeeResponse response = XBeeResponse();
// create reusable response objects for responses we expect to handle 
ZBRxResponse rx = ZBRxResponse();

void setup(){
  xSerial.begin(9600);
  xbee.setSerial(xSerial);
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("hello, tang!");
  delay(3000);  
}

void loop(){
  xbee.readPacket();
  if (xbee.getResponse().isAvailable()) {
      // got something
      lcd.setCursor(0, 1);
      lcd.print( "MSG");
      if (xbee.getResponse().getApiId() == ZB_RX_RESPONSE) {
        // got a zb rx packet
        // now fill our zb rx class
        xbee.getResponse().getZBRxResponse(rx);
        lcd.setCursor(0, 1);
        lcd.print(rx.getData(1));

        if (rx.getOption() == ZB_PACKET_ACKNOWLEDGED) {
            // the sender got an ACK
            lcd.setCursor(0,1);
            lcd.print( "ACK");

        } else {
            lcd.setCursor(0,1);
            lcd.print("ERROR");
        }
      } else {
        // not something we were expecting
        //flashLed(errorLed, 1, 25);   
       lcd.print("7 print"); 
      }
    } else if (xbee.getResponse().isError()) {
      lcd.print("error");
    }
    delay(3000);
}

啊，我将 xbee s2 连接到 arduino 上的 xbee pro shield。 xbee shield 上没有 dline/uart 开关。所以，我使用软件序列库...但它没有工作。

【问题讨论】：

您是否确认（可能与 X-CTU 一起）XBee 无线电已形成网络？您是否从 XBee 获得任何帧？您的 XBee 库是否配置为使用 ATAP=2 而不是 ATAP=1？你有正确的波特率吗？如果将接收 XBee 连接到运行 X-CTU 的计算机，它会显示接收到的帧吗？您确认什么是有效的并且您是否完全隔离了问题？

【解决方案1】：

我已经用 Arduino 完成了两个 XBee 之间的通信，你可以看看我的编码并尝试改变你的编码。

发件人 =

#include <SoftwareSerial.h>
#define Dout 2
#define Din 3
#define LED 9
SoftwareSerial XBeeSerial (Dout, Din);

void setup() {  
XBeeSerial.begin(9600);
pinMode(LED, OUTPUT);
}

void loop() {

delay(500);
XBeeSerial.write("+");
analogWrite(LED,13);
delay(3000);
XBeeSerial.write("-");
analogWrite(LED,0);
delay(500);
}

接收者 =

#include<SoftwareSerial.h>
#define LED 9
#define Dout 2
#define Din 3
SoftwareSerial XBeeSerial( Dout, Din);
char XBee_message;

void setup() {
Serial.begin(9600);
XBeeSerial.begin(9600);
pinMode(LED, OUTPUT);
}

void loop() {
while(XBeeSerial.available()) {
  XBee_message = XBeeSerial.read();
  Serial.print(XBee_message);

 switch (XBee_message){
 case '+':
 analogWrite(LED, 13);
 break;
 case '-':
 analogWrite(LED, 0);
 break;
 default:  
 analogWrite(LED, 0);
}
}
}
