/id like to use wifi manager to add more credentials without hard coding ,SSID,PASSWORD,BOTID ,TOKEN and Camera identity im struggling to get ESP32-cam to communicate with telegram ive also tried OTP to secure the credentials but nothing works , here is the code below:/

#include <WiFiManager.h> #include <Preferences.h> #include <WiFiClientSecure.h> #include <UniversalTelegramBot.h> #include <ArduinoJson.h>

// Wi-Fi and Telegram WiFiManager wm; Preferences preferences; WiFiClientSecure client; UniversalTelegramBot bot("YOUR_BOT_TOKEN", client); // Replace with your bot token String chat_id = "YOUR_CHAT_ID"; // Replace with your chat ID String botToken, botId, camId;

// Replace with your SMS API or function String phoneNumber = "+1234567890"; // Your phone number to receive OTP String generatedOTP = "123456"; // Placeholder OTP, replace with real OTP generation String password = wm.getWiFiPass(); // Correct function

// Function to send the OTP to the specified phone number void sendOTP() { Serial.println("Sending OTP to phone: " + phoneNumber); // Example: Use an SMS API like Twilio to send OTP (for now it just simulates) }

// Function to verify the OTP input bool verifyOTP(String otpInput) { return otpInput == generatedOTP; // Verify the input OTP }

void setup() { Serial.begin(115200); client.setInsecure(); // Required for Telegram to skip SSL cert verification preferences.begin("credentials", false);

// Load saved credentials String storedSSID = preferences.getString("ssid", ""); String storedPassword = preferences.getString("password", ""); botToken = preferences.getString("botToken", ""); botId = preferences.getString("botId", ""); camId = preferences.getString("camId", "");

// WiFi Manager setup WiFiManagerParameter custom_botId("botId", "Enter BOT ID", botId.c_str(), 50); WiFiManagerParameter custom_botToken("botToken", "Enter Bot Token", botToken.c_str(), 50); WiFiManagerParameter custom_camId("camId", "Enter Camera Identity", camId.c_str(), 50);

wm.addParameter(&custom_botId); wm.addParameter(&custom_botToken); wm.addParameter(&custom_camId);

if (storedSSID == "") { // Open Wi-Fi Manager if no credentials if (!wm.autoConnect("ESP")) { Serial.println("Failed to connect to Wi-Fi Manager"); }

// Save new credentials
preferences.putString("ssid", wm.getWiFiSSID());
preferences.putString("password", wm.getWiFiPass());
preferences.putString("botId", custom_botId.getValue());
preferences.putString("botToken", custom_botToken.getValue());
preferences.putString("camId", custom_camId.getValue());

} else { // Connect to saved Wi-Fi credentials WiFi.begin(storedSSID.c_str(), storedPassword.c_str()); if (WiFi.waitForConnectResult() != WL_CONNECTED) { Serial.println("Failed to connect to Wi-Fi"); } else { Serial.println("Connected to Wi-Fi"); } }

// Telegram Connection Test bool botConnected = bot.getMe(); // returns true if connected if (botConnected){ Serial.println("Telegram Bot Connected!"); bot.sendMessage(chat_id, "Bot is now online!", ""); } else { Serial.println("Failed to connect to Telegram Bot."); } }

// Access WiFi Manager after OTP verification void accessWiFiManager() { String otpInput;

// Send OTP to phone sendOTP();

Serial.println("Enter the OTP sent to your phone:"); while (Serial.available() == 0) { // Wait for user to enter OTP via serial }

otpInput = Serial.readStringUntil('\n');

if (verifyOTP(otpInput)) { Serial.println("OTP verified. Accessing Wi-Fi Manager."); // Open Wi-Fi Manager for credential changes if (!wm.startConfigPortal("ESP")) { Serial.println("Failed to start Wi-Fi Manager"); } else { Serial.println("Wi-Fi Manager opened."); } } else { Serial.println("Invalid OTP. Access denied."); } }

// Function to handle Telegram messages void handleTelegramMessages() { int numNewMessages = bot.getUpdates(bot.last_message_received + 1); while (numNewMessages) { for (int i = 0; i < numNewMessages; i++) { String text = bot.messages[i].text;

  // Start Command
  if (text == "/start") {
    bot.sendMessage(chat_id, "Welcome! Type /otp to get your OTP.", "");
  }

  // OTP Command
  else if (text == "/otp") {
    sendOTP();
    bot.sendMessage(chat_id, "OTP sent to your phone number.", "");
  }
}
numNewMessages = bot.getUpdates(bot.last_message_received + 1);

} }

void loop() { // Monitor Telegram messages handleTelegramMessages();

// Monitor if user wants to access Wi-Fi Manager again via OTP if (Serial.available() > 0) { String input = Serial.readStringUntil('\n'); if (input == "reset") { accessWiFiManager(); } } }
