The NDEF NFC protocol is often a ways of getting together with NFC Forum devices directly as mapped through the NFP provider pub/sub model. Any client applying this protocol will be required to discover how to encode and decode NDEF packets. For publishing messages, a customer would merely specify the sort as NDEF protocol, because the rest of the type information is embedded inside NDEF message itself. Publishing NDEF NFC protocol types allows complaintant nearly direct pass-through access to send NDEF messages over NFC. To sign up, litigant would specify NEDF.
NFC Logical Link Control Protocol (LLCP) Technical Specification
Defines an OSI layer-2 protocol to aid peer-to-peer communication between two NFC-enabled devices, which can be essential for any NFC applications which entail bi-directional communications. The specification defines two service types, connectionless and connection-oriented, organized into three link service classes: connectionless service only connection-oriented service only and both connectionless and connection-oriented service. The connectionless service offers minimal setup without any reliability or flow-control guarantees (deferring these problems to applications also to the reliability guarantees offered by ISO/IEC 18092 and ISO/IEC 14443 MAC layers). The bond-oriented service adds in-order, reliable delivery, flow-control, and session-based service layer multiplexing.
LLCP can be a compact protocol, in line with the industry standard IEEE 802.2, designed to support either small applications with limited data transport requirements, including minor file transfers, or network protocols, such as OBEX and TCP/IP, which often supply a more robust service environment for applications. The NFC LLCP thus features a solid foundation for peer-to-peer applications, raising the basic functionality available from ISO/IEC 18092, but without impacting the interoperability of legacy NFC applications or chipsets.
NFC standards cover communications protocols and data exchange formats and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa.[6] The factors include ISO/IEC 18092[7] and the ones defined by the NFC Forum.
