Build status


WinBeacon is a managed .NET (C#) library with a minimal Bluetooth LE Stack that is able to detect and act as an iBeacon¹. This stack doesn't support BLE devices, only the detection and transmission of BLE advertisement packets used by beacons.

Supported operating systems

  • Windows XP (not tested, but it should work)
  • Windows 7
  • Windows 8
  • Windows 10*

* For Windows 10, you should be able to use BluetoothLEAdvertisementWatcher instead of this library.

Supported BT4.0 LE dongles

Manufacturer Product Chipset VID / PID Compatible
ASUS USB-BT400 BCM20702A0 VID_0B05 PID_17CB Yes
Belkin Mini Bluetooth 4.0 Adapter Class 2.10M BCM20702A0 VID_050D PID_065A Yes
Pluggable USB Bluetooth 4.0 Low Energy Micro Adapter BCM20702A0 VID_0A5C PID_21E8 Yes
CSR USB Bluetooth 4.0 CSR8510 VID_0A12 PID_0001 Yes

If anyone can test with other BT4.0 dongle types, please let me know how it works out or send us a pull request.


This library needs raw USB access to a BT4.0 dongle. Therefore you should replace the original driver of the dongle with a WinUSB driver. This also means that the default Bluetooth stack is no longer used and Windows will no longer detect the dongle as a Bluetooth dongle until you re-install the original drivers.

To replace or create a WinUSB driver for the BT4.0 dongle, we advise you to use the Zadig tool.

Get it on NuGet

Install-Package WinBeacon


Detecting beacons

using (var hub = new BeaconHub(0x050D, 0x065A))
    hub.BeaconDetected += (sender, e) =>
			Console.WriteLine("Detected beacon: {0}", e.Beacon);

Advertise as a beacon

using (var hub = new BeaconHub(0x050D, 0x065A))
    hub.EnableAdvertising(new Beacon("B9407F30-F5F8-466E-AFF9-25556B57FE6D", 1000, 2000, -52));
