Windows Driver Kit DDI reference (ns-bthddi-_brb)

_BRB structure

Description

Profile drivers use Bluetooth request blocks (BRBs), to send requests to the Bluetooth driver stack. The BRB structure defines the format for all supported commands that can be sent to a Bluetooth device.

Members

`BrbHeader`

Describes basic information about the request being sent to the Bluetooth device. For more information, see BRB_HEADER.

`BrbGetDeviceInterfaceString`

Defines the format for a command to get the interface string of the current Bluetooth device object. For more information about getting the device interface string, see _BRB_GET_DEVICE_INTERFACE_STRING.

`BrbL2caRegisterServer`

Defines the format for a command to register a L2CAP server. For more information about registering a L2CAP server, see _BRB_L2CA_REGISTER_SERVER.

`BrbL2caUnregisterServer`

Defines the format for a command to unregister a previously registered L2CAP server. For more information about unregistering a L2CAP server, see _BRB_L2CA_UNREGISTER_SERVER.

`BrbL2caOpenChannel`

Defines the format of the L2CAP open channel and the L2CAP open channel response commands sent to the Bluetooth device. For more information about opening a L2CAP channel, see _BRB_L2CA_OPEN_CHANNEL.

`BrbL2caCloseChannel`

Defines the format of a L2CAP close channel command sent to the Bluetooth device. For more information about closing a L2CAP channel, see _BRB_L2CA_CLOSE_CHANNEL.

`BrbL2caPing`

Defines the format of a command that sends a L2CAP_EchoReq message to and receives a L2CAP_EchoRsp message from a remote Bluetooth device over a L2CAP connection. For more information about pinging a L2CAP connection, see _BRB_L2CA_PING.

`BrbL2caAclTransfer`

Defines the format of a command that performs read and write operations over a L2CAP connection to a Bluetooth device. For more information about ACL transfers, see _BRB_L2CA_ACL_TRANSFER.

`BrbGetLocalBdAddress`

Defines the format of a command that returns the address of the local Bluetooth radio. For more information about getting the local Bluetooth device address, see _BRB_GET_LOCAL_BD_ADDR.

`BrbPsm`

Defines the format for the commands that register and unregister a Protocol/Service Multiplexer (PSM) that L2CAP Bluetooth devices connect to. For more information about PSMs, see _BRB_PSM.

`BrbL2caUpdateChannel`

Defines the format of a command that updates the settings of a L2CAP channel to a Bluetooth device. For more information about updating a L2CAP channel, see _BRB_L2CA_UPDATE_CHANNEL.

`BrbScoRegisterServer`

Defines the format for a command to register a SCO server. For more information about registering a SCO server, see _BRB_SCO_REGISTER_SERVER.

`BrbScoUnregisterServer`

Defines the format for a command to unregister a previously registered SCO server. For more information about unregistering a SCO server, see _BRB_SCO_UNREGISTER_SERVER.

`BrbScoOpenChannel`

Defines the format of SCO open channel and the SCO open channel response commands sent to the Bluetooth device. For more information about opening a SCO channel, see _BRB_SCO_OPEN_CHANNEL.

`BrbScoCloseChannel`

Defines the format of a SCO close channel command sent to the Bluetooth device. For more information about closing a SCO channel, see _BRB_SCO_CLOSE_CHANNEL.

`BrbScoFlushChannel`

Defines the format of a SCO flush channel command. For more information about flushing a SCO channel, see _BRB_SCO_FLUSH_CHANNEL.

`BrbScoTransfer`

Defines the format of a command that reads isochronous data from or writes data to a SCO channel from a Bluetooth device. For more information, see _BRB_SCO_TRANSFER.

`BrbScoGetChannelInfo`

Defines the format of a command that reads the settings of a SCO channel to a Bluetooth device. For more information about SCO transfers, see _BRB_SCO_GET_CHANNEL_INFO.

`BrbScoGetSystemInfo`

Defines the format of a command that reads the SCO settings of the local system. For more information about getting local SCO settings, see _BRB_SCO_GET_SYSTEM_INFO.

`BrbAclGetMode`

Defines the format of a command to get the current ACL mode. For more information about getting the current ACL mode, see _BRB_ACL_GET_MODE.

`BrbAclEnterActiveMode`

Defines the format of a command to enter active ACL mode. For more information about entering active ACL mode, see _BRB_ACL_ENTER_ACTIVE_MODE.

`BrbL2caOpenEnhancedChannel`

Defines the format of the enhanced L2CAP open channel and the enhanced L2CAP open channel response commands sent to the Bluetooth device. For more information about opening an enhanced L2CAP channel, see _BRB_L2CA_OPEN_ENHANCED_CHANNEL. This member is present in Windows 8 and later versions of Windows.
