Question

我已经启动ardulink mqtt来收听arduino uno的模拟引脚1 按照以下步骤在Windows 10上使用mosquitto mqtt代理1.5.8运行 C：\ Java \ jdk1.8.0_201 \ bin \ java -jar ardulink-mqtt-2.1.0.jar -a 1-连接“ ardulink：// serial-jssc？port = COM3＆pingprobe = false”-独立

尽管我通过home / devices / ardulink / A1 / value / get订阅了主题，但我仍未得到任何答复。

我看不到ardulink日志或mosquitto日志中的任何发布

在Arduino串行监视器上，我确实看到Serial.print的所有输出，表明该草图实际上已完全上传到Arduino uno。

arduino代码

int sensorValue;
// variable to calibrate low value
int sensorLow = 1023;
// variable to calibrate high value
int sensorHigh = 0;



void setup() {

 Serial.begin(115200);

  // calibrate for the first five seconds after program runs
  while (millis() < 5000) {
    // record the maximum sensor value
    sensorValue = analogRead(A1);
    if (sensorValue > sensorHigh) {
      sensorHigh = sensorValue;
    }
    // record the minimum sensor value
    if (sensorValue < sensorLow) {
      sensorLow = sensorValue;
    }
  }

}

void loop() {
  //read the input from A1 and store it in a variable
  sensorValue = analogRead(A1);


Serial.print(sensorValue);
  // wait for a moment
  delay(1000);
}

Answer 1

似乎您没有将Ardulink草图刷新到Arduino，而是自写的东西（它不会通过串行链接发送任何消息）。刷新Ardulink草图并再次启动java mqtt客户端后，一切都应正常工作。

Answer 2

在包含标准ardulink协议后，我设法解决了该问题，以下是经过修订的arduino代码。

int sensorValue;
// variable to calibrate low value
int sensorLow = 1023;
// variable to calibrate high value
int sensorHigh = 0;
// LED pin
const int ledPin = 13;
String inputString = "";         // a string to hold incoming data (this is general code you can reuse)
boolean stringComplete = false;  // whether the string is complete (this is general code you can reuse)
void setup() {
  // Make the LED pin an output and turn it on
  Serial.begin(115200);

  Serial.print("alp://rply/");
  Serial.print("ok?id=0");
  Serial.print('\n'); // End of Message
  Serial.flush();

  pinMode(ledPin, OUTPUT);
  digitalWrite(ledPin, HIGH);

  // calibrate for the first five seconds after program runs

  while (millis() < 5000) {
    // record the maximum sensor value
    sensorValue = analogRead(A1);
    if (sensorValue > sensorHigh) {
      sensorHigh = sensorValue;
    }
  // record the minimum sensor value
    if (sensorValue < sensorLow) {
      sensorLow = sensorValue;
    }
  }


  digitalWrite(ledPin, LOW);
}

void loop() {
  //read the input from A1 and store it in a variable
  serialEvent();
  sensorValue = analogRead(A1);



  if (stringComplete==true){

   if(inputString.startsWith("alp://")) {
         boolean msgRecognized = true;
         if (inputString.substring(6,10)=="ared"){
                //Serial.println(sensorValue);
                digitalWrite(ledPin, HIGH);

         }else{

           msgRecognized = false; 
         }

 // Prepare reply message if caller supply a message id (this is general code you can reuse)
      int idPosition = inputString.indexOf("?id=");
      if(idPosition != -1) {
        String id = inputString.substring(idPosition + 4);
        // print the reply
        Serial.print("alp://rply/");
        if(msgRecognized) { // this sketch doesn't know other messages in this case command is ko (not ok)
          Serial.print("ok?id=");
        } else {
          Serial.print("ko?id=");
        }
        Serial.print(id);
        Serial.print('\n'); // End of Message
        Serial.flush();

      }




  }
// clear the string:
   inputString = "";
   stringComplete = false;
  }

if (sensorValue>0){

        Serial.print("alp://ared/");
        Serial.print("1");
        Serial.print("/");
        Serial.print(sensorValue);
        Serial.print('\n'); // End of Message
        Serial.flush();


}



   delay(1000);








}



void serialEvent() {


  while (Serial.available()>0&&!stringComplete==true) {

    // get the new byte:
    char inChar = (char)Serial.read();
    // add it to the inputString:
    inputString += inChar;

    // if the incoming character is a newline, set a flag
    // so the main loop can do something about it:
    if (inChar == '\n') {
      stringComplete = true;
    }
  }
}

Ardulink 2无法使用Serial.print
