对于在使用 Arduino 的时候出现的这种问题，可以考虑使用不同的解决方案来避免 .read() 函数干扰 BLE 连接。以下是一个代码示例：

#include 
#include 
#include 

BLECharacteristic *pCharacteristic;
bool deviceConnected = false;
uint8_t txValue = 0;

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

  // 创建 BLE 设备
  BLEDevice::init("MyBLE");

  // 创建 BLE 服务
  BLEServer *pServer = BLEDevice::createServer();
  BLEService *pService = pServer->createService(SERVICE_UUID);

  // 创建 BLE 特征值
  pCharacteristic = pService->createCharacteristic(
                      CHARACTERISTIC_UUID,
                      BLECharacteristic::PROPERTY_NOTIFY |
                      BLECharacteristic::PROPERTY_READ |
                      BLECharacteristic::PROPERTY_WRITE
                    );

  pCharacteristic->addDescriptor(new BLE2902());

  // 开始服务
  pService->start();

  // 开始广播
  BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();
  pAdvertising->addServiceUUID(SERVICE_UUID);
  pAdvertising->setScanResponse(true);
  pAdvertising->setMinPreferred(0x06);
  pAdvertising->setMinPreferred(0x12);
  BLEDevice::startAdvertising();
}

void loop() {
  // Handle BLE disconnect
  if (!deviceConnected && BLEDevice::getConnections()->begin()) {
      BLEDevice::getConnections()->clear();
      deviceConnected = true;
  }

  // Handle BLE connect
  if (deviceConnected && !BLEDevice::getConnections()->begin()) {
      deviceConnected = false;
  }

  // Update characteristic value when device connected
  if (deviceConnected) {
      txValue++;
      pCharacteristic->setValue(&txValue, 1);
      pCharacteristic->notify();
      delay(10);
  }
}

可以看到，在这个示例中，我们没有使用 .read() 方法，而是使用了 BLECharacteristic 类的 setValue() 方法来设置 BLE 特征值，在 BLE 连接建立后使用 notify() 方法来将变更
