INDICATION_CODE enumeration (bthddi.h)

  • Article

The INDICATION_CODE enumeration type indicates to a profile driver what type of L2CAP event has occurred.

Syntax

typedef enum _INDICATION_CODE {
  IndicationAddReference,
  IndicationReleaseReference,
  IndicationRemoteConnect,
  IndicationRemoteDisconnect,
  IndicationRemoteConfigRequest,
  IndicationRemoteConfigResponse,
  IndicationFreeExtraOptions,
  IndicationRecvPacket,
  IndicationPairDevice,
  IndicationUnpairDevice,
  IndicationUnpersonalizeDevice,
  IndicationRemoteConnectLE
} INDICATION_CODE, *PINDICATION_CODE;

Constants

 
IndicationAddReference
Indicates to a profile driver to add a reference to its device object because it may be called at
any time.
IndicationReleaseReference
Indicates to a profile driver to release a reference to its device object and that it will no
longer be called.
IndicationRemoteConnect
Indicates to a server profile driver that a remote device is connecting to the PSM that the
profile driver registered earlier. Profile drivers accept or reject this request by
building and sending a

BRB_L2CA_OPEN_CHANNEL_RESPONSE request. When this indication code is passed, the profile driver
should use the parameters that are passed to it in the
Connect member of the

INDICATION_PARAMETERS structure.
IndicationRemoteDisconnect
Indicates to a registered profile driver that a remote device disconnecting from the local radio.
When this indication code is passed, the profile driver should use the parameters that are passed to it
in the
Disconnect member of the INDICATION_PARAMETERS structure.
IndicationRemoteConfigRequest
Indicates to a client profile driver that a remote device is performing a configuration request.
When this indication code is passed, the profile driver should use the parameters that are passed to it
in the
ConfigRequest member of the INDICATION_PARAMETERS structure.
IndicationRemoteConfigResponse
Indicates to a client profile driver that a remote device is responding to a configuration
request. When this indication code is passed, the profile driver should use the parameters that are
passed to it in the
ConfigResponse member of the INDICATION_PARAMETERS structure.
IndicationFreeExtraOptions
Reserved for future use. Do not use.
IndicationRecvPacket
Indicates to a registered profile driver that a packet has been received on the specified PSM. The
profile driver can use this event to determine when it is necessary to issue a read
BRB_L2CA_ACL_TRANSFTER BRB. Profile drivers that need to read from the remote device can also ignore
this notification and keep a read BRB pending at all times. When this indication code is passed, the
profile driver should use the parameters that are passed to it in the
RecvPacket member of the

INDICATION_PARAMETERS structure.
IndicationPairDevice
Indicates to a registered driver that the local radio has bonded to a specific remote
radio.
IndicationUnpairDevice
Indicates to a registered driver that the local radio is no longer bonded to a specific remote
radio.
IndicationUnpersonalizeDevice
Indicates to a registered driver that the specified remote radio has been removed from the list of
personal devices.
IndicationRemoteConnectLE
Indicates to a server profile driver that a low energy (LE) remote device is connecting to the PSM that the
profile driver registered earlier. Profile drivers accept or reject this request by
building and sending a

BRB_L2CA_OPEN_CHANNEL_RESPONSE request. When this indication code is passed, the profile driver
should use the parameters that are passed to it in the
Connect member of the

INDICATION_PARAMETERS structure. This value is present in Windows 8 and later versions of Windows.

Remarks

A value from this enumeration is passed to a profile driver's L2CAP Callback Function to notify it of an event.
