Bluetooth OS Functions (Windows Embedded CE 6.0)

1/6/2010

The functions that you can use when developing your Bluetooth OS design are exported from Btdrt.dll, and are provided to help you develop either a shell or dedicated application functionality in the absence of a WinSock layer. You can call these functions from an application other than the Bluetooth stack layer, in device.exe.

Most of these functions have an equivalent WinSock function, which is the preferred way to access Bluetooth functionality because of convenience and code portability within the Win32 family.

The following table shows the functions that you can use when developing your Bluetooth OS design.

Programming element Description

This function retrieves the address of the Bluetooth peer device authentication of which requires the personal identification number (PIN) code.

BthGetRemoteCOD

This functions retrieves the COD for a specified device that has a baseband connection with the local device.

BthNsLookupServiceBegin

This function initiates a client query that is constrained by the information contained within a WSAQUERYSET (Bluetooth) structure.

BthNsLookupServiceEnd

This function frees the handle after previous calls to the BthNsLookupServiceBegin and BthNsLookupServiceNext functions.

BthNsLookupServiceNext

This function retrieves the results of an SDP search.

BthNsSetService

This function adds, updates, or removes service records from the local SDP database.

BthPairRequest

This function requests the personal identification number (PIN) for a Bluetooth device.

BthPerformInquiry

This function performs an Inquiry operation.

BthReadAuthenticationEnable

This function reads the value for the authentication setting.

BthReadCOD

This function reads adapter's class of device.

BthReadLinkPolicySettings

This function reads the current link policy for the existing connection with the peer that is specified by its Bluetooth address.

BthReadLocalAddr

This function retrieves the Bluetooth address of the current device.

BthReadLocalVersion

This function Reads the version and capabilities of Host Controller Interface (HCI) and Link Manager Protocol (LMP) stacks on the Bluetooth device.

It is a combination of the following two HCI commands:

  • Read_Local_Version_Information
  • Read_Local_Supported_Features

BthReadPageTimeout

This function retrieves the current page timeout value.

BthReadRemoteVersion

This function reads the version and capabilities of Link Manager Protocol (LMP) stack on the Bluetooth device. It is a combination of the following two HCI commands: Read_Remote_Version_Information and Read_Remote_Supported_Features.

BthReadScanEnableMask

This function reads the adapter's scan mode.

BthRefusePINRequest

This function refuses an outstanding PIN request that is retrieved by BthGetPINRequest function.

BthRemoteNameQuery

This function queries the name of a remote Bluetooth device.

BthRevokeLinkKey

This function removes the link key for a Bluetooth device.

BthRevokePIN

This function revokes the PIN for the Bluetooth device.

BthSetCODInquiryFilter

This function sets the Inquiry Filter to a specified class of device (COD).

BthSetEncryption

This function requests that the encryption mode on an existing connection is switched with the peer device.

BthSetInquiryFilter

This function sets the Inquiry Filter to a specified address.

BthSetLinkKey

This function stores the link key for the Bluetooth device.

BthSetPIN

This function stores the PIN for the Bluetooth device.

BthSetSecurityUI

This function allows an application to provide an event that will be signaled by the stack when a device without a PIN sends a PIN request.

BthTerminateIdleConnections

This function disconnects all idle connections held by the L2CAP layer.

BthWriteAuthenticationEnable

This function sets the value for the authentication setting.

BthWriteCOD

This function sets adapter's class of device.

BthWriteLinkPolicySettings

This function writes the current link policy for the existing connection with the peer specified by its Bluetooth address.

BthWritePageTimeout

This function configures the page timeout.

BthWriteScanEnableMask

This function sets the adapter's scan mode.
