Arduino Telegram机器人通知消息

Question

我正在尝试使用Arduino，DHT11和Telegram机器人创建监视系统。我试图发送一条消息开始，但看来arduino和电报之间的连接未建立。串行监视器打印出“电话未成功发送”消息。但是，它不会给出任何错误。请帮忙。

#include <ESP8266WiFi.h>

#include <WiFiClientSecure.h>
#include <ArduinoJson.h>

// Initialize Wifi connection to the router 
#define WIFI_SSID "xxxxx"                                             // input your home or public wifi name 
#define WIFI_PASSWORD "xxxxxx" 

// Initialize Telegram BOT 
#define BOTtoken "xxxxxxxxxxxxxxxxxxxxxxxxxxxx"
#define CHAT_ID "xxxxxxxxxxxxx"

//Create a new WiFi client
WiFiClientSecure client; //For ESP8266 boards

//Create a bot with the token and client 
UniversalTelegramBot bot(BOTtoken, client);

void setup() {
  Serial.begin(57600); 
    WiFi.begin(WIFI_SSID, WIFI_PASSWORD);                                     //try to connect with wifi
    Serial.print("Connecting to ");
    Serial.print(WIFI_SSID);
    while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);

  }
  Serial.println();
  Serial.print("Connected to ");
  Serial.println(WIFI_SSID);
  Serial.print("IP Address is : ");
  Serial.println(WiFi.localIP());

  if (bot.sendMessage(CHAT_ID, "Bot started up")){
    Serial.println("TELEGRAM Successfully sent");
  }
  else{
    Serial.println("TELEGRAM NOT Successfully sent");
  }
} 

void loop() {

}
