Member Function Documentation

◆ onAttMtuChange()

void onAttMtuChange	(	ble::connection_handle_t	connectionHandle,
		uint16_t	attMtuSize
	)

overridevirtual

Function invoked when the connections changes the ATT_MTU which controls the maximum size of an attribute that can be read in a single L2CAP packet which might be fragmented across multiple packets.

Parameters

connectionHandle	The handle of the connection that changed the size.
attMtuSize

See also: negotiateAttMtu()

Reimplemented from GattServer::EventHandler.

Definition at line 40 of file ChainableGattServerEventHandler.h.

◆ onDataSent()

void onDataSent ( const GattDataSentCallbackParams & params )

overridevirtual

Function invoked when the server has sent data to a client.

For notifications this is triggered when data is sent, for indications it's only triggered when the confirmation has been received.

Note: params has a temporary scope and should be copied by the application if needed later

Reimplemented from GattServer::EventHandler.

Definition at line 45 of file ChainableGattServerEventHandler.h.

◆ onDataWritten()

void onDataWritten ( const GattWriteCallbackParams & params )

overridevirtual

Function invoked when a client writes an attribute.

Note: params has a temporary scope and should be copied by the application if needed later

Reimplemented from GattServer::EventHandler.

Definition at line 49 of file ChainableGattServerEventHandler.h.

◆ onDataRead()

void onDataRead ( const GattReadCallbackParams & params )

overridevirtual

Function invoked when a client reads an attribute.

Note: This functionality may not be available on all underlying stacks. Application code may work around that limitation by monitoring read requests instead of read events.; params has a temporary scope and should be copied by the application if needed later
