#include <BLEUtils.h>

void setup() {
  Serial.begin(9600);
  BLEDevice::init("ESP32_BT");
  BLEServer *pServer = BLEDevice::createServer();
  BLEService *pService = pServer->createService(BLEUUID("180F"));
  BLECharacteristic *pCharacteristic = pService->createCharacteristic(
    BLEUUID("2A37"),
    BLECharacteristic::PROPERTY_READ | BLECharacteristic::PROPERTY_WRITE);
  pCharacteristic->setValue("Hello World");
  pService->start();
  pServer->getAdvertising()->start();
  Serial.println("Server started");
}

void loop() {
  if (Serial.available()) {
    String value = Serial.readString();
    pCharacteristic->setValue(value);
  }
}
```
