我有一个 Windows 7 应用程序，它使用Stollmann SDK成功地将 PC 与 Android 绑定。蓝牙 MAC 地址、哈希和随机器的双向交换通过 NFC在带外进行：
遗憾的是，Windows 应用程序的源代码无法在此处共享。在 Android 端，不需要任何应用程序，一旦收到 NDEF 消息，操作系统（由HandoverManager ？）执行安全简单配对。application/vnd.bluetooth.ep.oob
现在我正在尝试创建一个 Android 应用程序，它将使用单向身份验证通过扫描的 QR 码（而不是 NFC）执行 OOB 配对。
自定义二维码将显示在 PC 屏幕上（由ZXing.Net生成）并包含蓝牙 MAC 地址、哈希和随机数。
然而，OOB 绑定似乎尚未在 Android 中实现 -

if (getState() != STATE_ON) return null;

我的问题：
由于 OOB 蓝牙配对在 Android 上的 NFC 上运行良好 - 你认为有一种（hackish）方法可以通过 QR 码来做同样的事情吗？
也许（疯狂的想法）通过HandoverManager提供虚假的 NDEF 消息？
