When a Bluetooth LE device is paired with a Windows machine, the device becomes part of the system. The following diagram illustrates the way objects are structured inside a typical GATT service. Compliant service implementations are constructed from characteristics organized in a way that conforms to the established schema defined on the Bluetooth Special Interest Group developer website. Profiles that are developed on this technology are organized into the generic attribute profile (GATT).Įach profile defines the use of one or more services to create a use case or scenario. This sample shows how to accomplish all those things:īluetooth drivers should be installed automatically for the Bluetooth LE device in your laptop, one way to check that Bluetooth LE is running normally is by going to Device Manager->Check the status of your inbox Bluetooth radio (it should be listed underīluetooth, you should also see a "Microsoft Bluetooth LE Enumerator", that means that your Bluetooth LE radio is working properly, if you don't se it please give us more details about what laptop/radio combination you are using.Bluetooth LE introduces a new physical layer that shares the same frequency space as Bluetooth basic rate.
On a characteristic value that supports them, this will make sure that a connection is automatically established when your device is in range. If your requirements also include auto-reconnecting when the device is in reach, you'll need to register for notifications or indications If you need to monitor the connection state you can use a DeviceWatcher to monitor the PnP Connected State of the device. Will automatically attempt to establish a connection to the device if it's not already connected, if a connection attempt failed because the device was not there, you'll get an Unreachable GattCommunicationStatus.Ģ.
In order to uses your device with Windows, it must first be paired, once paired the Windows Bluetooth stack handles connections to your device automatically, if you need to write something to the device, just call WriteCharacteristicValueAsync, that The way to use Bluetooth LE devices in Windows Store Apps in Windows 8.1 is through the GenericAttributeProfile namespace ( )ġ.
