bthhfpddi.h header
This header is used by audio. For more information, see:
bthhfpddi.h contains the following programming interfaces:
IOCTLs
| IOCTL_BTHHFP_DEVICE_GET_CODEC_ID An audio driver can send an IOCTL_BTHHFP_DEVICE_GET_CODEC_ID control code to query the Bluetooth driver stack about the codec ID used by the HFP service. This helps the audio driver determine the sampling rate for the data. |
| IOCTL_BTHHFP_DEVICE_GET_CONNECTION_STATUS_UPDATE The IOCTL_BTHHFP_DEVICE_GET_CONNECTION_STATUS_UPDATE IOCTL Gets a connection status update. |
| IOCTL_BTHHFP_DEVICE_GET_CONTAINERID The IOCTL_BTHHFP_DEVICE_GET_CONTAINERID IOCTL Gets the PnP Container ID of the Bluetooth device. |
| IOCTL_BTHHFP_DEVICE_GET_DESCRIPTOR The audio driver issues the IOCTL_BTHHFP_DEVICE_GET_DESCRIPTOR control code to get information about an enabled GUID_DEVINTERFACE_BLUETOOTH_HFP_SCO_HCIBYPASS device interface. |
| IOCTL_BTHHFP_DEVICE_GET_DESCRIPTOR2 The IOCTL_BTHHFP_DEVICE_GET_DESCRIPTOR2 IOCTL Gets descriptive information about the paired Handsfree profile (HFP) device. |
| IOCTL_BTHHFP_DEVICE_GET_KSNODETYPES The IOCTL_BTHHFP_DEVICE_GET_KSNODETYPES IOCTL Gets the KSNODE types that best describe the Bluetooth device’s input and output. |
| IOCTL_BTHHFP_DEVICE_GET_NRECDISABLE_STATUS_UPDATE The IOCTL_BTHHFP_DEVICE_GET_NRECDISABLE_STATUS_UPDATE IOCTL Gets noise reduction / echo cancellation (NREC) Disable status updates from the remote Bluetooth device. |
| IOCTL_BTHHFP_DEVICE_GET_VOLUMEPROPERTYVALUES The IOCTL_BTHHFP_DEVICE_GET_VOLUMEPROPERTYVALUES IOCTL returns KSPROPERTY_VALUES data for the KSPROPERTY_AUDIO_VOLUMELEVEL property. |
| IOCTL_BTHHFP_DEVICE_REQUEST_CONNECT The IOCTL_BTHHFP_DEVICE_REQUEST_CONNECT IOCTL requests a Handsfree Profile (HFP) Service Level Connection to the Bluetooth device. |
| IOCTL_BTHHFP_DEVICE_REQUEST_DISCONNECT The IOCTL_BTHHFP_DEVICE_REQUEST_DISCONNECT IOCTL removes the Handfree Profile (HFP) Service Level Connection that existed between the audio driver and the Bluetooth device. |
| IOCTL_BTHHFP_MIC_GET_VOLUME_STATUS_UPDATE The IOCTL_BTHHFP_MIC_GET_VOLUME_STATUS_UPDATE IOCTL Gets the volume level setting of the Bluetooth device's microphone. |
| IOCTL_BTHHFP_MIC_SET_VOLUME The IOCTL_BTHHFP_MIC_SET_VOLUME IOCTL sets the volume level of the microphone for the Bluetooth device. |
| IOCTL_BTHHFP_SPEAKER_GET_VOLUME_STATUS_UPDATE The IOCTL_BTHHFP_SPEAKER_GET_VOLUME_STATUS_UPDATE IOCTL Gets the volume level setting of the Bluetooth device's speaker. |
| IOCTL_BTHHFP_SPEAKER_SET_VOLUME The IOCTL_BTHHFP_SPEAKER_SET_VOLUME IOCTL sets the volume level for the speaker of the Bluetooth device. |
| IOCTL_BTHHFP_STREAM_CLOSE The IOCTL_BTHHFP_STREAM_CLOSE IOCTL indicates that the client driver no longer requires the synchronous connection-oriented (SCO) channel for streaming audio. |
| IOCTL_BTHHFP_STREAM_GET_STATUS_UPDATE The IOCTL_BTHHFP_STREAM_GET_STATUS_UPDATE IOCTL Gets a stream channel status update. |
| IOCTL_BTHHFP_STREAM_OPEN The IOCTL_BTHHFP_STREAM_OPEN IOCTL requests an open synchronous connection-oriented (SCO) channel to transmit audio data over the air. |
Functions
| BTHHFP_AUDIO_DEVICE_CAPABILTIES_INIT The BTHHFP_AUDIO_DEVICE_CAPABILTIES_INIT method returns a pointer to an initialized BTHHFP_AUDIO_DEVICE_CAPABILTIES data structure. |
Structures
| BTHHFP_AUDIO_DEVICE_CAPABILTIES The BTHHFP_AUDIO_DEVICE_CAPABILTIES data structure describes the capabilities of a Bluetooth HFP device, including the version and whether it supports 16 kHz sampling. |
| BTHHFP_DESCRIPTOR The BTHHFP_DESCRIPTOR data structure stores information describing a paired Handsfree profile (HFP) device. |
| BTHHFP_DESCRIPTOR2 The BTHHFP_DESCRIPTOR2 data structure stores information describing a paired Handsfree profile (HFP) device. |
| HFP_BYPASS_CODEC_ID_V1 The HFP_BYPASS_CODEC_ID_V1 structure defines version 1 of the supported codec ID structure. |
Enumerations
| HFP_BYPASS_CODEC_ID_VERSION The HFP_BYPASS_CODEC_ID_VERSION enumeration defines the codec ID structure versions that are supported by the HFP service. |
