Detailed Description

A class that discovers Bluetooth® devices.

Note:Below are 3 methods for doing discovery. They are platform specific. Do not attempt to implement all 3 methods.
Note: There are no cancel discovery methods. Be carefull when using these to properly dispose of discoverer objects if navigating prior to finishing discovery.

using LinkOS.Plugin;
using LinkOS.Plugin.Abstractions;

private void StartBluetoothDiscovery()
{
    IDiscoveryEventHandler handler = DiscoveryHandlerFactory.Current.GetInstance();
    handler.OnDiscoveryError += DiscoveryHandler_OnDiscoveryError;
    handler.OnDiscoveryFinished += DiscoveryHandler_OnDiscoveryFinished;
    handler.OnFoundPrinter += DiscoveryHandler_OnFoundPrinter;

    //For Android 
    BluetoothDiscoverer.Current.FindPrinters(MainActivity.Context, handler);
    //For iOS
    BluetoothDiscoverer.Current.FindPrinters(null, handler);
    //For Forms apps: implement the previous two methods in OS code projects (PrinterDiscoveryImplementation.cs)
    DependencyService.Get<IPrinterDiscovery>().FindBluetoothPrinters(handler);
}
private void OnFoundPrinter(IDiscoveryHandler handler, IDiscoveredPrinter discoveredPrinter)
{
    Device.BeginInvokeOnMainThread(() => {
        printerList.Add(discoveredPrinter);
    });
}
private void OnDiscoveryError(IDiscoveryHandler handler, string message)
{
    System.Diagnostics.Debug.WriteLine("Discovery Error: " + message);
}
private void OnDiscoveryFinished(IDiscoveryHandler handler, string message)
{
    System.Diagnostics.Debug.WriteLine("Discovery Compete");
}
