Can someone give me a simple code of sending a "Hi" message on Whatsapp or Telegram using esp8266 or esp32. I had tried many things but failed with esp8266. Should use esp32 ?

Here are the codes I had used :

#include <ESP8266WiFi.h>
#include <SoftwareSerial.h>
#include <WiFiClientSecure.h>
#include <UniversalTelegramBot.h>

const char* ssid = "XXXXX";
const char* password = "XXXXX;
#define BOTtoken "XXXXX";
#define CHAT_ID "XXXXX";

SoftwareSerial serial(5, 4); // RX, TX

X509List cert(TELEGRAM_CERTIFICATION_ROOT);
WiFiClientSecure client;
UniversalTelegramBot bot(BOTtoken, client);

void setup() {
  Serial.begin(115200);
  serial.begin(9600);

  // Connect to Wi-Fi
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}

void loop() {
  // Read float value from Arduino via RX pin
  float receivedFloat = receiveFloatData();

  if (!isnan(receivedFloat)) {
    // Construct the message to be sent
    String message = "Name: Sam\n" + String(receivedFloat);

    // Send the message to the specified Telegram group
    sendTelegramMessage(message);

    delay(5000); // Adjust the delay as needed
  }
}

float receiveFloatData() {
  float data = 0.0;
  while (serial.available() > 0) {
    char incomingByte = serial.read();
    if (incomingByte == '\n') {
      break; // End of the float value
    }
    data = data * 10.0 + (incomingByte - '0');
  }
  return data;
}

void sendTelegramMessage(String message) {
  if (bot.sendMessage(chatId, message, "Markdown")) {
    Serial.println("Message sent successfully");
  } else {
    Serial.println("Failed to send message");
  }
}

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <UniversalTelegramBot.h>
#include <SoftwareSerial.h>

const char* ssid = "XXXXX"; // Enter your WIFI SSID
const char* password = "XXXXX"; // Enter your WIFI Password

#define BOTtoken "XXXXX" // Enter the bottoken you got from botfather

#define CHAT_ID "XXXXX" // Enter your CHAT_ID you got from CHAT_ID bot

SoftwareSerial mySerial(5, 4); // RX, TX
X509List cert(TELEGRAM_CERTIFICATE_ROOT);

UniversalTelegramBot bot(BOTtoken, client);

// Function declaration for sendMessage
void sendMessage(String message);

void setup() {
Serial.begin(115200);
mySerial.begin(9600);

client.setTrustAnchors(&cert);

WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);

int a = 0;
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(500);
a++;
}

Serial.println("");
Serial.println("WiFi connected");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
sendMessage("Wifi Connected!");
sendMessage("System has Started!!");
}

void loop() {
String msg = mySerial.readStringUntil('\r');
Serial.println(msg);
sendMessage(msg);
delay(5000);
}

// Function definition for sendMessage
void sendMessage(String message) {
int response = bot.sendMessage(CHAT_ID, message, "Markdown");
if (response == 200) {
Serial.println("Message sent successfully");
}
else {
Serial.print("Failed to send message. HTTP error code: ");
Serial.println(response);
