可以使用Arduino Portenta H7的蓝牙模块与Windows设备进行连接。以下是一份示例代码，可以在Arduino IDE中运行。

首先，需要在Arduino IDE中安装BLE库。在Arduino IDE中，选择“Sketch” -> “Include Library” -> “Manage Libraries”，搜索“BLE”并安装该库。

接下来，可以使用以下代码将Arduino Portenta H7的蓝牙模块与Windows设备进行连接。

#include

BLEServer *pServer = NULL; BLECharacteristic *pCharacteristic = NULL; bool deviceConnected = false; float txValue = 0;

#define SERVICE_UUID "4fafc201-1fb5-459e-8fcc-c5c9c331914b" #define CHARACTERISTIC_UUID_TX "beb5483e-36e1-4688-b7f5-ea07361b26a8" #define CHARACTERISTIC_UUID_RX "beb5483e-36e1-4688-b7f5-ea07361b26a8"

class MyServerCallbacks : public BLEServerCallbacks { void onConnect(BLEServer* pServer) { deviceConnected = true; }

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

};

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

// 创建BLEServer BLEDevice::init("PortentaBLE"); pServer = BLEDevice::createServer(); pServer->setCallbacks(new MyServerCallbacks());

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

// 创建BLE特征 pCharacteristic = pService->createCharacteristic( CHARACTERISTIC_UUID_TX, BLECharacteristic::PROPERTY_NOTIFY );

pCharacteristic->addDescriptor(new BLE2902());

BLECharacteristic *pCharacteristic = pService->createCharacteristic( CHARACTERISTIC_UUID_RX, BLECharacteristic::PROPERTY_WRITE );

pService->start();

// 启动BLE广播 BLEAdvertising *pAdvertising = BLEDevice::getAdvertising(); pAdvertising->addServiceUUID(pService->getUUID()); pAdvertising->setScanResponse(true); pAdvertising->setMinPreferred(0x06); // 最小间隔: 0.625ms pAdvertising->setMinPreferred(0x12); // 最大间隔: 1.25ms BLEDevice::startAdvertising(); }

void loop() { if (deviceConnected) { pCharacteristic->setValue((uint8_t*)&txValue, sizeof(tx
