[英]Bluetooth Low Energy API Windows 8
我需要为Windows 8编写一个桌面应用程序,该应用程序可以与低功耗蓝牙设备进行通信。 经过研究,我认为这仅适用于Windows应用程序,而不适用于桌面应用程序,因为没有API。 是否可以在桌面应用程序中为Windows应用程序使用API?
谢谢

}
void temperatureMeasurementChanged(GattCharacteristic sender, GattValueChangedEventArgs eventArgs)
{
byte[] temperatureData = new byte[eventArgs.CharacteristicValue.Length];

您可以从桌面应用程序访问WinRT API(Windows Apps)。 只需按照以下链接中的步骤操作:

但是请注意,您需要Windows 8.1才能使用BLE功能。
