两个Arduino之间以api模式进行Xbee通信

Question

我有两个Arduino Unos，两个LCD和Xbee s2。 我将两个xbee s2模块连接到每个arduino uno。 我仔细搜索了此实现并进行了尝试。 但是，它没有用。 我感谢您的帮助。

配置：AP = 2协调器API和路由器API

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);

      xbee.getResponse().getZBTxStatusResponse(txStatus);

      if (txStatus.getDeliveryStatus() == SUCCESS) {
        lcd.setCursor(0,1);
        lcd.print("Success");
      } else {

      }

    //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
  }

啊，我将xbee s2连接到arduino上的xbee pro防护板。 xbee防护罩上没有dline / uart开关。 因此，我使用软件串行库...但是它没有用。

我已经用Arduino完成了两个XBee之间的通信，您可以看一下我的编码，然后尝试稍微更改一下编码。
