如何从C ++代码扫描并连接到广告BLE设备？

Question

I'm trying to search and connect to advertising Bluetooth Low Energy devices from C++ code. I would like a piece of code to use laptop's wireless chip to discover and connect to BLE devices, regardless of their GATT Services. I want in fine to use GATT properties (Services, Characteristics, Descriptors, Notification).

Programmatically

I have the BluetoothLEAdvertisementWatcher Class documentation from Windows API.

I tried to make working this example but without good results.

I also tried this example , but no success.

Manually

I figured out using Windows 10 Action Center, and use manual pairing to connect devices (because Windows con see and connect my device).

Then I could use directely the Windows.Devices.Bluetooth.GenericAttributeProfile Namespace

Is there a way to implement that automatically?

Hello Raphaël and welcome to stackoverflow. When you say "without good results" or "but no success", you should detail why (compilation error, runtime error...).

I used this piece of code: Getting BLE Beacons in C++ Windows 10 Desktop Application

It compiles under Win10, so should the third link you posted ( https://github.com/urish/win-ble-cpp ) as it's very similar if you look at the includes here. Just note that this is not regular win32 projects: from Visual Studio you must create a new "Windows"/"Universal" C++ project, else they won't compile.

Alternatively, if you're OK with using a 3rd party library, you could simply use QtBluetooth , recent version supports windows 10. Then you can easily access BLE features from aregular win32 project.
