Java 获取Arduino UNO r3上XBee数据包的有效负载值

我正在做一个使用XBee S1作为发射机/接收机的项目。以下是我正在使用的硬件：

协调员：带XBee S1模块的XBee USB EXplorer v2.0

终端设备：带有XBee和XBee S1模块的r3.0

项目的目的很简单，即打开/关闭。以下是代码（控制器）：

这是Arduino（终端设备）的代码：

这些值保持不变，但我已将输入值从0更改为1

这是我的Java终端（控制台）的示例输出：

我确信这是有效负载值（用^^^^标记）：

但是如何通过Arduino获得这种价值呢

---

无论如何，我参考了教程。

好吧，在做了一些搜索之后，通过Arduino获得XBee有效负载值的最佳方法是使用，正如我读到的这个站点：。以下是获取“有效载荷”值的代码：

#include<Xbee.h>
int DEBUG = 13;
XBee xbee = XBee();
XBeeResponse response = XBeeResponse();
Rx16Response rx16 = Rx16Response();

void setup() {
  pinMode(DEBUG, OUTPUT);
  Serial.begin(9600);
  DEBUG = 0;
}

void loop() {
 xbee.readPacket();

 if(xbee.getResponse().isAvailable()){
   lcd.print("Data received");
     if(xbee.getResponse().getApiId() == RX_16_RESPONSE){
       xbee.getResponse().getRx16Response(rx16);

       uint8_t payload = rx16.getData(0);//this is the payload value, easy to get it :D
     }
 }     
}

#包括
int-DEBUG=13；
XBee XBee=XBee（）；
XBEERResponse response=XBEERResponse（）；
Rx16Response rx16=Rx16Response（）；
无效设置（）{
pinMode（调试、输出）；
Serial.begin（9600）；
调试=0；
}
void循环（）{
xbee.readPacket（）；
if（xbee.getResponse（）.isAvailable（））{
lcd.打印（“收到的数据”）；
if（xbee.getResponse（）.getapid（）==RX\u 16\u RESPONSE）{
xbee.getResponse（）.getRx16Response（rx16）；
uint8_t payload=rx16.getData（0）；//这是有效负载值，很容易得到：D
}
}     
}

那是！！：D

#include <LiquidCrystal.h>
int LED = 12;                //Turn this LED on or off, depending on packet rx'd
int debugLED = 13;           //Flash light to indicate rx
int packet;                 //Packet will be two bytes in length
int analogValue;
int debugValue = 0;
int discard;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  pinMode(LED, OUTPUT);
  pinMode(debugLED, OUTPUT);
  Serial.begin(9600);
  packet = 0x01;
  lcd.begin(16,2);
}

void loop() {
 lcd.setCursor(0, 1); 
 if(Serial.available() >= 16){     //<--Changing the value from 21 to 16 fixed the problem! 

    debugValue = 0;

    debugValue = Serial.read();

    if(debugValue == 0x7e){      //Look for starting byte
      lcd.clear();
      lcd.print(debugValue);
      delay(500);
      digitalWrite(debugLED, HIGH);    //Flash Arduino LED (not the one on digital pin 11)
      delay(1000);                          //to indicate rx'ing data
      digitalWrite(debugLED, LOW);
      //lcd.print(debugValue);


      for(int i = 2; i != 10; i++){      //Discard unused data (see XBee API protocol for more info)
        discard = Serial.read();
        if (i != 8)
          packet = discard;
          // print the number of seconds since reset:
         if(i == 5)
         lcd.setCursor(0,1);
         lcd.print(packet);
         delay(500);
      }
      lcd.print(discard);
   }
 }
 if(packet == 0x7e)
     digitalWrite(LED, HIGH);
 else
     digitalWrite(LED, LOW);
}
