Detailed Description

Implementation of NFCForum Logical Link Control Protocol (LLCP) 1.1.

Macro Definition Documentation

PHLN_LLCP_SW_ID

#define PHLN_LLCP_SW_ID   0x01

ID for Software LLCP layer.

Event posted by Reader library thread to the application thread once LLCP is activated.

Enumeration Type Documentation

phlnLlcp_PType

enum phlnLlcp_PType

Protocol Data Unit (PDU) type.

Enumerator
PHLN_LLCP_PTYPE_SYMM	Symmetry PDU.
PHLN_LLCP_PTYPE_PAX	Parameter Exchange concerning the LLCP Link configuration.
PHLN_LLCP_PTYPE_AGF	Aggregated Frame.
PHLN_LLCP_PTYPE_UI	Unnumbered Information to transfer service data units to the peer LLC.
PHLN_LLCP_PTYPE_CONNECT	CONNECT PDU is an unnumbered PDU which is used to request a data link connection.
PHLN_LLCP_PTYPE_DISC	Disconnect is an unnumbered PDU which is used to terminate a data link connection.
PHLN_LLCP_PTYPE_CC	Connection Complete is used by an LLC to acknowledge the receipt and acceptance of the CONNECT.
PHLN_LLCP_PTYPE_DM	Disconnected Mode is used to report status indicating that the LLC is logically disconnected.
PHLN_LLCP_PTYPE_FRMR	Frame Reject is used to report the receipt of a inappropriate PDU.
PHLN_LLCP_PTYPE_SNL	Service Name Lookup used to discover the availability of named services.
PHLN_LLCP_PTYPE_INFO	Information is used to transfer service data units.
PHLN_LLCP_PTYPE_RR	Receive Ready to acknowledge one or more received I PDUs and indicate that the LLC is able to receive subsequent Information PDUs (I PDUs).
PHLN_LLCP_PTYPE_RNR	Receive Not Ready is used by LLC to indicate a temporary inability to process subsequent I PDUs.

Function Documentation

phlnLlcp_Sw_Init()

phStatus_t phlnLlcp_Sw_Init	(	phlnLlcp_Sw_DataParams_t *	pDataParams,

Operation successful.

Parameters

[in]	pDataParams	Pointer to this layer's parameter structure.
[in]	wSizeOfDataParams	Specifies the size of the data parameter structure.
[out]	pLocalGenBytes	Pointer to General data bytes buffer (Length of the buffer should be between min 6bytes and max 20bytes based on number the TLV to be framed).
