Assistant: Конечно! Этот код на C++ предназначен для работы с Bluetooth Low Energy (BLE) на микроконтроллере ESP32. Вот краткое пояснение:

1. **Подключение библиотек и объявление переменных**:
    ```cpp
    #include <NimBLEDevice.h>

    BLEServer* pServer = NULL;
    BLECharacteristic* pCharacteristic = NULL;
    bool deviceConnected = false;
    bool oldDeviceConnected = false;
    uint32_t value = 0;
    ```

2. **Определение UUID для сервиса и характеристики**:
    ```cpp
    #define SERVICE_UUID        "4fafc201-1fb5-459e-8fcc-c5c9c331914b"
    #define CHARACTERISTIC_UUID "beb5483e-36e1-4688-b7f5-ea07361b26a8"
    ```

3. **Создание класса обратных вызовов для сервера BLE**:
    ```cpp
    class MyServerCallbacks: public BLEServerCallbacks {
        void onConnect(BLEServer* pServer) {
          deviceConnected = true;
          BLEDevice::startAdvertising();
        };

        void onDisconnect(BLEServer* pServer) {
          deviceConnected = false;
        }

        uint32_t onPassKeyRequest(){
          Serial.println("Server PassKeyRequest");
          return 123456; 
        }

        bool onConfirmPIN(uint32_t pass_key){
          Serial.print("The passkey YES/NO number: ");Serial.println(pass_key);
          return true; 
        }

        void onAuthenticationComplete(ble_gap_conn_desc desc){
          Serial.println("Starting BLE work!");
        }
    };
    ```

4. **Функция `setup()` для инициализации BLE**:
    ```cpp
    void setup() {
      Serial.begin(115200);

      BLEDevice::init("ESP32");

      pServer = BLEDevice::createServer();
      pServer->setCallbacks(new MyServerCallbacks());

      BLEService *pService = pServer->createService(SERVICE_UUID);

      pCharacteristic = pService->createCharacteristic(
                          CHARACTERISTIC_UUID,
                          NIMBLE_PROPERTY::READ   |
                          NIMBLE_PROPERTY::WRITE  |
                          NIMBLE_PROPERTY::NOTIFY |
                          NIMBLE_PROPERTY::INDICATE
                        );

      pService->start();

      BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();
      pAdvertising->addServiceUUID(SERVICE_UUID);
      pAdvertising->setScanResponse(false);
      pAdvertising->setMinPreferred(0x0);

      BLEDevice::startAdvertising();
      Serial.println("Waiting a client connection to notify...");
    }
    ```

5. **Функция `loop()` для обработки соединений и уведомлений**:
    ```cpp
    void loop() {
        if (deviceConnected) {
            pCharacteristic->setValue((uint8_t*)&value, 4);
            pCharacteristic->notify();
            value++;
            delay(10);
        }

        if (!deviceConnected && oldDeviceConnected) {
            delay(500);
            pServer->startAdvertising();
            Serial.println("start advertising");
            oldDeviceConnected = deviceConnected;
        }

        if (deviceConnected && !oldDeviceConnected) {
            oldDeviceConnected = deviceConnected;
        }
    }
    ```

Этот код создает BLE сервер на ESP32, который может подключаться к клиентам, отправлять уведомления и обрабатывать аутентификацию. Если у тебя есть конкретные вопросы по коду, не стесняйся спрашивать!
User: В код необходимо добавить второй сервис TAG_SERVICE и характеристики TAG, TIME  с правами на запись. первый сервис переименовать в LED_SERVICE. при записи значений в характеристики первого сервиса, эти значения отправить через характеристики второго сервиса в виде строки TAG;TIME
