Called when advertising starts.

Parameters

event Advertising start event.

Note: Check event.getStatus() to see if advertising started successfully

See also: startAdvertising()

Reimplemented in ChainableGapEventHandler.

Definition at line 326 of file Gap.h.

◆ onAdvertisingEnd()

virtual void onAdvertisingEnd ( const AdvertisingEndEvent & event )

virtualinherited

Called when advertising ends.

Advertising ends when the process timeout or if it is stopped by the application or if the local device accepts a connection request.

Parameters

event Advertising end event.

Note: Check event.getStatus() to see if advertising ended successfully

See also: stopAdvertising(); onConnectionComplete()

Reimplemented in ChainableGapEventHandler.

Definition at line 343 of file Gap.h.

◆ onAdvertisingReport()

virtual void onAdvertisingReport ( const AdvertisingReportEvent & event )

virtualinherited

Called when a scanner receives an advertising or a scan response packet.

Parameters

event Advertising report.

See also: startScan()

Reimplemented in ChainableGapEventHandler.

Definition at line 354 of file Gap.h.

◆ onScanTimeout()

virtual void onScanTimeout ( const ScanTimeoutEvent & event )

virtualinherited

Called when scan times out.

Parameters

event Associated event.

See also: startScan()

Reimplemented in ChainableGapEventHandler.

Definition at line 365 of file Gap.h.

◆ onPeriodicAdvertisingSyncEstablished()

virtual void onPeriodicAdvertisingSyncEstablished ( const PeriodicAdvertisingSyncEstablishedEvent & event )

virtualinherited

Called when first advertising packet in periodic advertising is received.

Parameters

event Periodic advertising sync event.

Version: : 5+.

See also: createSync()

Reimplemented in ChainableGapEventHandler.

Definition at line 378 of file Gap.h.

◆ onPeriodicAdvertisingReport()

virtual void onPeriodicAdvertisingReport ( const PeriodicAdvertisingReportEvent & event )

virtualinherited

Called when a periodic advertising packet is received.

Parameters

event Periodic advertisement event.

Version: : 5+.

See also: createSync()

Reimplemented in ChainableGapEventHandler.

Definition at line 393 of file Gap.h.

◆ onPeriodicAdvertisingSyncLoss()

virtual void onPeriodicAdvertisingSyncLoss ( const PeriodicAdvertisingSyncLoss & event )

virtualinherited

Called when a periodic advertising sync has been lost.

Parameters

event Details of the event.

Version: : 5+.

See also: createSync()

Reimplemented in ChainableGapEventHandler.

Definition at line 408 of file Gap.h.

◆ onConnectionComplete()

virtual void onConnectionComplete ( const ConnectionCompleteEvent & event )

virtualinherited

Called when connection attempt ends.

Check event.getStatus() to see if connection was established. If this device is the peripheral and it was advertising this will end the advertising set which will also create the onAdvertisingEnd event.

See also: startAdvertising(); connect()

Parameters

event Connection event.

Reimplemented in ChainableGapEventHandler.

Definition at line 424 of file Gap.h.

◆ onUpdateConnectionParametersRequest()

virtual void onUpdateConnectionParametersRequest ( const UpdateConnectionParametersRequestEvent & event )

Application must accept the update with acceptConnectionParametersUpdate() or reject it with rejectConnectionParametersUpdate().

Parameters

event The connection parameters requested by the peer.

Version: 4.1+.

Note: This event will only be produced if manageConnectionParametersUpdateRequest() was called with true. Otherwise the stack will handle the request and no event will be generated.

Reimplemented in ChainableGapEventHandler.

Definition at line 445 of file Gap.h.

◆ onConnectionParametersUpdateComplete()

virtual void onConnectionParametersUpdateComplete ( const ConnectionParametersUpdateCompleteEvent & event )

virtualinherited

Called when connection parameters have been updated.

Parameters

event The new connection parameters.

◆ onReadPhy()

virtual void onReadPhy	(	ble_error_t	status,
		connection_handle_t	connectionHandle,
		phy_t	txPhy,
		phy_t	rxPhy
	)

virtualinherited

Function invoked when the current transmitter and receiver PHY have been read for a given connection.

Parameters

status	Status of the operation: BLE_ERROR_NONE in case of success or an appropriate error code.
connectionHandle	The handle of the connection for which the PHYs have been read.
txPhy	PHY used by the transmitter.
rxPhy	PHY used by the receiver.

See also: readPhy().

Version: : 5+.

Reimplemented in ChainableGapEventHandler.

Definition at line 494 of file Gap.h.

◆ onPhyUpdateComplete()

virtual void onPhyUpdateComplete	(	ble_error_t	status,
		connection_handle_t	connectionHandle,
		phy_t	txPhy,
		phy_t	rxPhy
	)

virtualinherited

Function invoked when the update process of the PHY has been completed.

The process can be initiated by a call to the function setPhy, the local bluetooth subsystem or the peer.

Parameters

status	Status of the operation: BLE_ERROR_NONE in case of success or an appropriate error code.
connectionHandle	The handle of the connection on which the operation was made.
txPhy	PHY used by the transmitter.
rxPhy	PHY used by the receiver.

Note: Success doesn't mean the PHY has been updated it means both ends have negotiated the best PHY according to their configuration and capabilities. The PHY currently used are present in the txPhy and rxPhy parameters.

See also: setPhy()

Version: : 5+.

Reimplemented in ChainableGapEventHandler.

Definition at line 528 of file Gap.h.

◆ onDataLengthChange()

virtual void onDataLengthChange	(	connection_handle_t	connectionHandle,
		uint16_t	txSize,
		uint16_t	rxSize
	)

virtualinherited

Function invoked when the connections changes the maximum number of octets that can be sent or received by the controller in a single packet.

A single L2CAP packet can be fragmented across many such packets.

Note: This only triggers if controller supports data length extension and negotiated data length is longer than the default 23.

Parameters

connectionHandle	The handle of the connection that changed the size.
txSize	Number of octets we can send on this connection in a single packet.
rxSize	Number of octets we can receive on this connection in a single packet.

Reimplemented in ChainableGapEventHandler.

Definition at line 549 of file Gap.h.

◆ onPrivacyEnabled()

virtual void onPrivacyEnabled ( )

virtualinherited

Function invoked when the privacy subsystem has been enabled and is ready to be used.

See also: enablePrivacy()

Reimplemented in ChainableGapEventHandler.

Definition at line 563 of file Gap.h.
