使用GattCharacteristicNotificationTrigger在UWP中挂起后台任务注册 [英] Background task registration hangs in UWP with GattCharacteristicNotificationTrigger

问题描述

我正在尝试使用进程内后台任务来获取Bluetooth LE设备的通知.但是，以下代码挂在最后一行，不会返回:

I'm trying to use an in-process background task to get notifications of a Bluetooth LE device. However, the following code hangs at the last line and does not return:

var bldr = new BackgroundTaskBuilder();
bldr.Name = guid.ToString("N");
var trigger = new GattCharacteristicNotificationTrigger(ch);
bldr.SetTrigger(trigger);
bldr.Register();

在应用程序中使用基于事件的模型时，获取设备的通知是可行的.同样，使用TimeTrigger注册任务也可以，因此在应用清单中的声明是可以的.

Getting the notifications of the device works when using the event-based model in the application. Also, registering the task with a TimeTrigger works, so the declaration in the app manifest is ok.

计算机运行创建者更新"，但UWP设置为至少需要周年纪念"更新.

The computer runs the Creators Update, but the UWP is set to require the Anniversary update as a minimum.
