BluetoothSetLocalServiceInfo function (bluetoothapis.h)

The BluetoothSetLocalServiceInfo function sets local service information for a specific Bluetooth radio.

Syntax

DWORD BluetoothSetLocalServiceInfo(
  [in, optional] HANDLE                             hRadioIn,
  [in]           const GUID                         *pClassGuid,
  [in]           ULONG                              ulInstance,
  [in]           const BLUETOOTH_LOCAL_SERVICE_INFO *pServiceInfoIn
);

Parameters

[in, optional] hRadioIn

A handle of the Bluetooth radio device to specify local service information for. If NULL, BluetoothSetLocalServiceInfo searches for the first available local Bluetooth radio.

[in] pClassGuid

The GUID of the service to expose. This should match the GUID in the server-side INF file.

[in] ulInstance

An instance ID for the device node of the Plug and Play (PnP) ID.

[in] pServiceInfoIn

A pointer to a BLUETOOTH_LOCAL_SERVICE_INFO structure that describes the local service to set.

Return value

The BluetoothSetLocalServiceInfo function returns the following values:

Return code Description
ERROR_NOT_FOUND
 The specified Bluetooth radio was not detected.
ERROR_BAD_UNIT
 No Bluetooth radios were detected.
STATUS_INSUFFICIENT_RESOURCES
 Sufficient resources were not available to complete the operation. You can receive this error when more than 100 local physical device objects (PDOs) correspond to Bluetooth services.
STATUS_PRIVILEGE_NOT_HELD
 The caller does not have the required privileges. See the Remarks section for information about how to elevate privileges.

Remarks

BluetoothSetLocalServiceInfo is a user-mode API that is used only by profile driver developers to trigger the installation of a local service that is described by the service GUID in pClassGuid.

BluetoothSetLocalServiceInfo generates a Plug and Play (PnP) device ID in the form of "BTHENUM{ClassGuid}". For example, "BTHENUM{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}". User-mode applications can call BluetoothSetLocalServiceInfo subsequent times with the same service GUID but with a different instance ID to create multiple instances of the specified server-side profile.

To use Bluetooth APIs like BluetoothSetLocalServiceInfo, user-mode applications should link with BthProps.lib.

Warning  The process that calls BluetoothSetLocalServiceInfo must have the SE_LOAD_DRIVER_NAME privilege. A process running in the system or an administrator context can elevate its privilege by using the SDK LookupPrivilegeValue and AdjustTokenPrivileges functions. For more information about this see Installing a Bluetooth Device.
 
The BLUETOOTH_LOCAL_SERVICE_INFO structure is defined in the SDK BluetoothApis.h header file.
