UWP与设备取消配对失败
我目前正在开发现有UWP应用程序的功能,以测试设备的蓝牙设备的功能。因此,我目前面临两个问题:一个是主要问题: 我正在基于Windows Universal示例中的设备枚举和配对示例构建蓝牙功能。我可以成功地找到并列举BT设备,甚至与它们配对,但奇怪的是,我无法与该设备解除配对。 我编写的代码可以在这里找到,我添加了整个类,以便您能够在需要时完全测试:UWP与设备取消配对失败,uwp,bluetooth,enumeration,Uwp,Bluetooth,Enumeration,我目前正在开发现有UWP应用程序的功能,以测试设备的蓝牙设备的功能。因此,我目前面临两个问题:一个是主要问题: 我正在基于Windows Universal示例中的设备枚举和配对示例构建蓝牙功能。我可以成功地找到并列举BT设备,甚至与它们配对,但奇怪的是,我无法与该设备解除配对。 我编写的代码可以在这里找到,我添加了整个类,以便您能够在需要时完全测试: class UWP_Bluetooth { DeviceWatcher deviceWatcher; public String
