Question

我已成功连接到Xbees。一个通过XbeeExplorer连接到CPU，另一个是ElSequencer（一个lilypad arduino板）。连接效果很好，我可以使用串行监视器发送无线信号而不会出现问题。波特率，平移ID和目的地地址都正确且有效。事实是，奇怪的是，Xbee不断向Arduino发送数据。像各种串行信号一样。如果我把Arduino打印回收到的信号，

Serial.print(incomingByte);

我也开始看到无限的信号回来了。 Xbee在没有任何命令的情况下继续发送连续出版物意味着什么。这些值完全是随机的。喜欢： 126010 131005301080854 126010131005301080854 126010131005301080854 126010131005101080856 126010131005101080856 126010131005301080854 126010131005201080855

我的arduino代码如下。是一个简单的开关灯。由于Xbee不断发送随机信号，有时信号与编程的信号匹配，并且灯会打开或关闭。

int incomingByte;      // a variable to read incoming serial data into

void setup() {
  // initialize serial communication:
  Serial.begin(57600);

  // The EL channels are on pins 2 through 9
            // Initialize the pins as outputs
            pinMode(2, OUTPUT);  // channel A  
            pinMode(3, OUTPUT);  // channel B   
            pinMode(4, OUTPUT);  // channel C
            pinMode(5, OUTPUT);  // channel D    
            pinMode(6, OUTPUT);  // channel E
            pinMode(7, OUTPUT);  // channel F
            pinMode(8, OUTPUT);  // channel G
            pinMode(9, OUTPUT);  // channel H

}

void loop() {
  // see if there's incoming serial data:
  if (Serial.available() > 0) {
    // read the oldest byte in the serial buffer:
    incomingByte = Serial.read();
    Serial.print(incomingByte);

    //EL WIRES
    if (incomingByte == 'A') {
      digitalWrite(2, HIGH);
    }
   if (incomingByte == 'B') {
      digitalWrite(3, HIGH);
    }
   if (incomingByte == 'C') {
      digitalWrite(4, HIGH);
    }
   if (incomingByte == 'D') {
      digitalWrite(5, HIGH);
    }
   if (incomingByte == 'E') {
      digitalWrite(6, HIGH);
    }
   if (incomingByte == 'F') {
      digitalWrite(7, HIGH);
    }
   if (incomingByte == 'G') {
      digitalWrite(8, HIGH);
    }
   if (incomingByte == 'H') {
      digitalWrite(9, HIGH);
    }
   //
  if (incomingByte == 'I') {
      digitalWrite(2, LOW);
    }
   if (incomingByte == 'J') {
      digitalWrite(3, LOW);
    }
   if (incomingByte == 'L') {
      digitalWrite(4, LOW);
    }
   if (incomingByte == 'M') {
      digitalWrite(5, LOW);
    }
   if (incomingByte == 'N') {
      digitalWrite(6, LOW);
    }
   if (incomingByte == 'O') {
      digitalWrite(7, LOW);
    }
   if (incomingByte == 'P') {
      digitalWrite(8, LOW);
    }
   if (incomingByte == 'Q') {
      digitalWrite(9, LOW);
    } 
  }
}

Xbee奇怪地发送随机序列值
