Bluetooth Devices Reference
Overview of the Bluetooth devices reference technology.
To develop Bluetooth devices reference, you need these headers:
For programming guidance for this technology, see:
GUIDs
The following GUIDs are defined in the bthledef.h header file. To enumerate paired Bluetooth LE devices, you can use the SetupDiXxx Win32 enumeration APIs to enumerate devices of the GUID_BLUETOOTHLE_DEVICE_INTERFACE device interface class.
| GUID name, description | Value |
|---|---|
| GUID_BLUETOOTHLE_DEVICE_INTERFACE. Bluetooth LE device interface GUID. | 0x781aee18, 0x7733, 0x4ce4, 0xad, 0xd0, 0x91, 0xf4, 0x1c, 0x67, 0xb5, 0x92 |
| GUID_BLUETOOTH_GATT_SERVICE_DEVICE_INTERFACE. Bluetooth LE Service device interface GUID. | 0x6e3bb679, 0x4372, 0x40c8, 0x9e, 0xaa, 0x45, 0x09, 0xdf, 0x26, 0x0c, 0xd8 |
| BTH_LE_ATT_BLUETOOTH_BASE_GUID. Bluetooth base GUID. | 0x00000000, 0x0000, 0x1000, 0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB |
Enumerations
| BTH_LE_GATT_DESCRIPTOR_TYPE The BTH_LE_GATT_DESCRIPTOR_TYPE enumeration describes the different types of Bluetooth LE generic attributes (GATT). |
| BTH_LE_GATT_EVENT_TYPE The BTH_LE_GATT_EVENT_TYPE enumeration describes the different types of Bluetooth Low Energy (LE) generic attribute (GATT) profile events. |
Functions
| BluetoothGATTAbortReliableWrite Specifies the end of reliable write procedures, and the writes should be aborted. |
| BluetoothGATTBeginReliableWrite The BluetoothGATTBeginReliableWrite function specifies that reliable writes are about to begin. |
| BluetoothGATTEndReliableWrite Specifies the end of reliable writes, and the writes should be committed. |
| BluetoothGATTGetCharacteristics Gets all the characteristics available for the specified service. |
| BluetoothGATTGetCharacteristicValue Gets the value of the specified characteristic. |
| BluetoothGATTGetDescriptors Gets all the descriptors available for the specified characteristic. |
| BluetoothGATTGetDescriptorValue Gets the value of the specified descriptor. |
| BluetoothGATTGetIncludedServices Gets all the included services available for a given service. |
| BluetoothGATTGetServices The BluetoothGATTGetServices function gets all the primary services available for a server. |
| BluetoothGATTRegisterEvent Registers a routine to be called back during a characteristic value change event on the given characteristic identified by its characteristic handle. |
| BluetoothGATTSetCharacteristicValue Writes the specified characteristic value to the Bluetooth device. |
| BluetoothGATTSetDescriptorValue Writes the specified descriptor value to the Bluetooth device. |
| BluetoothGATTUnregisterEvent Unregisters the given characteristic value change event. |
| BluetoothSetLocalServiceInfo Sets local service information for a specific Bluetooth radio. |
| IsBthLEUuidMatch Determines whether two UUIDs match each other. |
| PFNBLUETOOTH_GATT_EVENT_CALLBACK Profile drivers implement a Bluetooth GATT event callback to be called whenever the value of a specific characteristic changes. |
Structures
| BLUETOOTH_GATT_VALUE_CHANGED_EVENT The BLUETOOTH_GATT_VALUE_CHANGED_EVENT structure describes a changed attribute value. |
| BLUETOOTH_GATT_VALUE_CHANGED_EVENT_REGISTRATION The BLUETOOTH_GATT_VALUE_CHANGED_EVENT_REGISTRATION structure describes one or more characteristics that have changed. |
| BTH_LE_GATT_CHARACTERISTIC The BTH_LE_GATT_CHARACTERISTIC structure describes a Bluetooth Low Energy (LE) generic attribute (GATT) profile characteristic. |
| BTH_LE_GATT_CHARACTERISTIC_VALUE The BTH_LE_GATT_CHARACTERISTIC_VALUE structure describes a Bluetooth Low Energy (LE) generic attribute (GATT) profile characteristic value. |
| BTH_LE_GATT_DESCRIPTOR The BTH_LE_GATT_DESCRIPTOR structure describes a Bluetooth Low Energy (LE) generic attribute (GATT) profile descriptor. |
| BTH_LE_GATT_DESCRIPTOR_VALUE The BTH_LE_GATT_DESCRIPTOR_VALUE structure describes a parent characteristic. |
| BTH_LE_GATT_SERVICE The BTH_LE_GATT_SERVICE structure describes a Bluetooth Low Energy (LE) generic attribute (GATT) profile service. |
| BTH_LE_UUID The BTH_LE_UUID structure contains information about a Bluetooth Low Energy (LE) Universally Unique Identifier (UUID). |
