HM-10 BLE and Xamarin Forms with Xabre

Hi guys

I'm playing around with an Arduino to which I have purchased the HM-10 BLE module. Currently, I just try to see if I can actually discover bluetooth devices through a simple application.

For this purpose, I use Xabre.

The sample application is as follows:

namespace BluetoothExample
{
        public partial class MainPage : ContentPage
        {


        public MainPage()
        {
            Padding = new Thickness(0, 20, 0, 0);
            var listView = new ListView();
            listView.ItemsSource = refreshcmd();
            Content = listView;
        }

        public static List<IDevice> refreshcmd()
        {
            List<IDevice> deviceList = new List<IDevice>();
            var adapter = CrossBluetoothLE.Current.Adapter;
            adapter.DeviceDiscovered += (s, a) => deviceList.Add(a.Device);
            adapter.StartScanningForDevicesAsync();
            return deviceList;
        }
    }
}

Now, my experience with Xamarin is little. However what i try to achieve here, is to create a listview and populate it with the bluetooth devices that my phone discovers.

Obviously, it doesn't show anything in the table, when i use it on my physical phone.
My logic tells me that i should allow the phone time to actually scan the environment before populating the list. Furthermore it could probably be convenient to add an automatic update feature to the list. - so that once a BT device is discovered, it is added to deviceList and then appended to the listview.

Can any of you help me with this relatively simple issue? Thanks in advance
