Bluetooth scan C#

问题:

I'm developing a C# WinForms app on Windows 10. I want to perform a Bluetooth environment scan and get devices list all around the PC. I also want the RSSI of each device.

I have tried 32feet library but I can't access RSSI.

Have you a solution or should I migrate to WPF/UWP?

回答1:

ok, I have found a solution here.

1. You first have to install Windows10 development kit.

2. Then in your project you have to add this library:

   C:\Program Files (x86)\Windows Kits\10\UnionMetadata\Windows.winmd
   

   Or you can install the "UwpDesktop" NuGet Package.

3. This works with Console app, Winforms, WPF and UWP.

4. Here is a simple example:

   using Windows.Devices.Bluetooth.Advertisement;
   
   namespace BeaconExample
   {
       class Program
       {
           static void Main(string[] args)
           {
               var watcher = new BluetoothLEAdvertisementWatcher();
               watcher.Received += Watcher_Received;
               watcher.Start();
           }
   
           private static void Watcher_Received(BluetoothLEAdvertisementWatcher sender, BluetoothLEAdvertisementReceivedEventArgs args)
           {
               Console.WriteLine(args.BluetoothAddress.ToString("x") + ";" + args.RawSignalStrengthInDBm);
           }
       }
   }
