Seeing nearby bluetooth-low-energy devices, getting information about devices by triggering events (update, add,remove, enumerate devices) Seeing information about Gatt, Gap protocol services, characters, features and attributes. A console application that provides write, read and subscribe, communication between client and server.

Documentation

You can check the Bluetooth Documentation.pdf file I prepared for documentation.

Requirements:

Example of code:

public void StartWatcher()
       {
           try
           {

            string[] requestedProperties = { "System.Devices.Aep.DeviceAddress", "System.Devices.Aep.IsConnected", "System.Devices.Aep.Manufacturer", "System.Devices.Aep.ModelName", "System.Devices.Aep.ModelId" };

            deviceWatcher =
                      DeviceInformation.CreateWatcher(
                          BluetoothLEDevice.GetDeviceSelectorFromPairingState(false),
                              requestedProperties,
                              DeviceInformationKind.AssociationEndpoint);

            // Register event handlers before starting the watcher.
            // Added, Updated and Removed are required to get all nearby devices
            deviceWatcher.Added += DeviceWatcher_Added;
            deviceWatcher.Updated += DeviceWatcher_Updated;
            deviceWatcher.Removed += DeviceWatcher_Removed;

            // EnumerationCompleted and Stopped are optional to implement.
            deviceWatcher.EnumerationCompleted += DeviceWatcher_EnumerationCompleted;
            deviceWatcher.Stopped += DeviceWatcher_Stopped;


            // Start the watcher.
            deviceWatcher.Start();

        }

        catch (Exception ex)
        {

            Console.WriteLine("Exception -> ", ex.Message);
        }
    }
