在Windows 10上连接到BLE外围设备 [英] Connect to BLE peripheral on Windows 10

问题描述

我尝试连接到BLE外围设备.首先，我看广告:

I try to connect to BLE peripheral. First, I watch for advertisements:

watcher = new BluetoothLEAdvertisementWatcher { ScanningMode = BluetoothLEScanningMode.Active };
watcher.Received += WatcherOnReceived;
watcher.Start();

，并且在WatcherOnReceived回调中，我尝试创建BluetoothLEDevice

and in the WatcherOnReceived callback I try to create BluetoothLEDevice

public async void WatcherOnReceived(BluetoothLEAdvertisementWatcher sender, BluetoothLEAdvertisementReceivedEventArgs btAdv)
{
    BluetoothLEDevice bleDevice = await BluetoothLEDevice.FromBluetoothAddressAsync(btAdv.BluetoothAddress);
}

但是，我总是在WatcherOnReceived回调中得到bleDevice == null.为什么以及如何解决?在UWP应用程序中创建BLE设备的正确方法是什么?然后，我需要连接到该设备，发现其GATT服务和特征，在其中一些上启用通知，并读/写其中一些.

However, I always get bleDevice == null in WatcherOnReceived callback. Why and how to fix it? What is the proper way of creating BLE device in UWP application? I then need to connect to that device, discover its GATT services and characteristics, enable notifications on some of them and read/write some of them.

推荐答案

此问题的答案很简单-不要在Windows 10上使用BLE.该API无法正常工作或行为随机，并且完全没有文档说明.我喜欢每个人都在谈论物联网是下一次工业革命，而微软在存在六年的BLE后仍无法使用BLE API.

The answer to this question is simple - do not use BLE on Windows 10. The API doesn't work or behaves randomly and is totally undocumented. I like everyone talking about IoT being next industrial revolution and Microsoft not having working BLE API after 6 year BLE exists.
