测试 Arduino WiFiServer 消息

Question

我需要在 Arduino 上制作一个 WiFiServer 以允许我向他发送命令来执行。但是有一个问题，当我给他发命令时，他测试命令但是测试总是错误的。

消息已正确发送和接收。

有代码：

#include <WiFi.h>

#define PORT 80
#define LED 8

char ssid[] = "trvl";
char pass[] = "ninja837";

String message;
int status = WL_IDLE_STATUS;

WiFiServer server(PORT);

void setup() {
  Serial.begin(9600);
  Serial.println("========================");
  Serial.println("TCP Serveur - Starting..");
  Serial.println("========================");

  pinMode(LED, OUTPUT);

  Serial.print("Try to connect to ssid: ");
  Serial.println(ssid);

  status = WiFi.begin(ssid, pass);
  if(status != WL_CONNECTED) {
    Serial.println("Couldn't connect to wifi network");
  }else{
    server.begin();
    Serial.print("Connected to wifi. Address: ");
    IPAddress myAddress = WiFi.localIP();
    Serial.println(myAddress);
  }


  Serial.println("Ready to use!");
  Serial.println();
}

void loop() {
  WiFiClient client = server.available();

  if(client) {
    if(client.available() > 0) {
      char ch = client.read();
      if(ch != '\n') {
        message += ch;
      }else{
        Serial.print("New message: '");
        Serial.print(message);
        Serial.println("'");

        //digitalWrite(LED, !digitalRead(LED));

        if(message.equals("on")) {
          digitalWrite(LED, HIGH);
          Serial.println("on");
        }else if(message.equals("off")) {
          digitalWrite(LED, LOW);
          Serial.println("off");
        }

        client.println(digitalRead(LED));
        client.flush();

        Serial.print("led: ");
        Serial.println(digitalRead(LED));

        message = "";
      }
    }
  }
}

And here is the monitor of Arduino

谢谢你的帮助

忘记使用 message.trim() 删除 \r
