Question

我尝试使用蓝牙在Windows和iOS之间进行通信。

在iOS方面，我发布广告，在窗口方面，我观看＆＃34;观看＆＃34;用于广告。

目前，在收到我的iOS设备正在发布的广告时，这些广告是空的。没有服务，没有ManufacturerData，DataSections列表包含1个DataSection，长度为1的数据（？）本地名称为空，这个广告包中没有任何用处。

当我调用# app/config/security.yml security: encoders: Delivery\AdminBundle\Entity\User: algorithm: bcrypt providers: our_db_provider: entity: class: DeliveryAdminBundle:User property: username access_control: - { path: ^/admin, roles: ROLE_USER } firewalls: main: pattern: ^/admin http_basic: ~ provider: our_db_provider（蓝牙地址）时，我得到一个对象，但是当我调用GetGattService时，所有内容都为空，没有服务，找不到异常的元素，DeviceInformation为空......就我而言没什么用处可以看到。

我不知道我在iOS上发布的广告是否有问题，或者我是如何在Windows上对待它的？侧。

以下是iOS代码：

    <?php
namespace Delivery\AdminBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;

/**
 * @ORM\Table(name="app_users")

 */
class User implements UserInterface, \Serializable

     */
    private $isActive;

    public function __construct()
    {
        $this->isActive = true;
        // may not be needed, see section on salt below
        // $this->salt = md5(uniqid(null, true));
    }

    public function getUsername()
    {
        return $this->username;
    }

    public function getSalt()
    {
        // you *may* need a real salt depending on your encoder
        // see section on salt below
        return null;
    }

    public function getPassword()
    {
        return $this->password;

    /** @see \Serializable::serialize() */
    public function serialize()

            $this->password,

    }

    /** @see \Serializable::unserialize() */
    public function unserialize($serialized)
    {
        list (
            $this->id,
            $this->username,
            $this->password,
            // see section on salt below
            // $this->salt
        ) = unserialize($serialized);
    }

    /**

    public function getId()
    {

    }

    {

        return $this;
    }

    /**

    public function setPassword($password)
    {
        if ($password) {
            $this->password = password_hash($password, PASSWORD_DEFAULT);
        }

        return $this;
    }

    /**

    public function setEmail($email)
    {
        $this->email = $email;

        return $this;
    }

    /**

    public function getEmail()
    {
        return $this->email;
    }

    /**

    public function getIsActive()
    {
        return $this->isActive;
    }
}

这是Windows C＃代码（暂时是一个简单的控制台应用程序）：

BluetoothLEDevice.FromBluetoothAddressAsync

对不起它有点乱......

提前感谢您的帮助，我也尝试了另一个方向（Windows广告和iOS观看）它也不顺利，这里是另一个问题我和＃39如果感兴趣，可以发表这个主题：Listening to and accepting a BLE Connect request in windows

广告是被动的，因此您应该将代码从主动更改为被动，例如： watcher.ScanningMode = BluetoothLEScanningMode.Passive;

public sealed partial class MainPage : Page
{
    Windows.Devices.Bluetooth.Advertisement.BluetoothLEAdvertisementWatcher advertisementWatcher;

    public MainPage()
    {
        this.InitializeComponent();

        advertisementWatcher = new Windows.Devices.Bluetooth.Advertisement.BluetoothLEAdvertisementWatcher();

        advertisementWatcher.ScanningMode = Windows.Devices.Bluetooth.Advertisement.BluetoothLEScanningMode.Passive;
        advertisementWatcher.Received += AdvertisementWatcher_Received;

        advertisementWatcher.Start();
    }

    private void AdvertisementWatcher_Received(Windows.Devices.Bluetooth.Advertisement.BluetoothLEAdvertisementWatcher sender, Windows.Devices.Bluetooth.Advertisement.BluetoothLEAdvertisementReceivedEventArgs args)
    {
        System.Diagnostics.Debug.WriteLine("Address: {0:X}", args.BluetoothAddress);
    }
}

仅使用.Received回调，您应该开始看到即将到来的数据，例如：

地址：A45E60F3E896地址：4BF5661A4EF2地址：549F476B5F37地址：4CB6DF3019A9地址：4BF5661A4EF2地址：106070EB42B1

在iOS设备上发布的Windows上接收BLE广告包
