To get started, register the IAdapter implementation in AppDelegate.cs and MainActivity.cs:
DependencyService.Register<IAdapter, Adapter>
Then, to retrieve the implementation from your cross-platform code:
DependencyService.Get<IAdapter>();
Note: You should only ever instantiate one instance of IAdapter. I have used the following code to use a single instance throughout my code:
private static readonly IAdapter _bluetoothAdapter;
public static IAdapter BluetoothAdapter { get { return _bluetoothAdapter; } }
static App() {
_bluetoothAdapter = DependencyService.Get<IAdapter>();
_bluetoothAdapter.ScanTimeout = TimeSpan.FromSeconds(10);
_bluetoothAdapter.ConnectionTimeout = TimeSpan.FromSeconds(10);
}
Then, the IAdapter can be retrieved with:
App.BluetoothAdapter
Once you have an IAdapter, see the documentation here for usage.
