ทำไมESP8266 V2 ไม่ขึ้นให้เลือกPort ขอรันเสร็จก็ขึ้นแบบนี้ครับ ผมต้องการส่งข้อความเข้าlineครับ

void Line_Notify(String message) ;

#include <ESP8266WiFi.h>

// Config connect WiFi

#define WIFI_SSID "xxxx"

#define WIFI_PASSWORD "xxxx"

// Line config

#define LINE_TOKEN "xxxxx"

#define SW D2

String message = "%E0%B9%82%E0%B8%94%E0%B8%99%E0%B8%81%E0%B8%94";

void setup() {

  pinMode(SW, INPUT);

  Serial.begin(9600);

  WiFi.mode(WIFI_STA);

  // connect to wifi.

  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);

  Serial.print("connecting");

  while (WiFi.status() != WL_CONNECTED) {

    Serial.print(".");

    delay(500);

  }

  Serial.println();

  Serial.print("connected: ");

  Serial.println(WiFi.localIP());

}

void loop() {

  if (digitalRead(SW) == HIGH) {

    while(digitalRead(SW) == HIGH) delay(10);

    Serial.println("Enter !");

    Line_Notify(message);

    // Serial.println();

  }

  delay(10);

}

void Line_Notify(String message) {

  WiFiClientSecure client;

  if (!client.connect("notify-api.line.me", 443)) {

    Serial.println("connection failed");

    return;   

  }

  String req = "";

  req += "POST /api/notify HTTP/1.1\r\n";

  req += "Host: notify-api.line.me\r\n";

  // Serial.println(req);

  client.print(req);

  delay(20);
