Witam wszystkich bardzo serdecznie.
Stworzyłem wg. różnych poradników bibliotekę bluetooth:

using System.Collections.Generic;

using System.Text;
using System.Threading.Tasks;
using Windows.Devices.Bluetooth;
using Windows.Devices.Bluetooth.Rfcomm;

I nie mam pojęcia jak zaimplementować to Page'a tak aby działało
(chodzi mi o zwykły komunikator WindowsMobile < - - - > Bluetooth <serial> Arduino <serial> PC)
i tak aby sterować arduino przez polecenia String ( /polecenie )
public async Task<DeviceInformationCollection> FindPairedDevicesAsync() to ComboBox
public async Task<bool> WriteAsync(string str) from TextBox
public async Task<String> ReadAsync() to TextBlock
Dopiero zaczynam zabawę z UWP i nie mam na razie za bardzo zaawansowanego pojęcia dot. wątków a tym bardziej dla mnie magia to sockety.
