NFC Forum Advances Seamless Data Exchange and Simplifies Development with Publication of 16th Specification
Simple NDEF Exchange Protocol Enables Common Data Format for Peer-to-Peer and Reader/Writer Modes
WAKEFIELD, Mass., USA - Sept. 29, 2011 - The NFC Forum, a non-profit industry association that advances the use of Near Field Communication (NFC) technology, has released its 16th specification, the Simple NDEF Exchange Protocol (SNEP). SNEP is an application-level protocol suitable for sending or receiving messages between two NFC-enabled devices. The new SNEP specification is available to the public for download at no charge.
SNEP Technical Information
SNEP allows an application on an NFC-enabled device to exchange NFC Data Exchange Format (NDEF) messages with another NFC-enabled device when operating in NFC Forum peer-to-peer mode. The protocol makes use of the NFC Logical Link Control Protocol (LLCP) connection-oriented transport mode to provide a reliable data exchange.
SNEP is a request/response protocol. A SNEP client application sends a request to a SNEP server application to either retrieve data from the server with a GET method or push data to the server using the PUT method. The protocol handles segmentation and reassembly of large messages as well as early cancellation of transfers that would exhaust receiving capabilities.
Beyond the protocol definition, the SNEP specification defines a default server that is available as a well-known service on an NFC-enabled device. This default server functions as a simple Inbox that applies locally defined processing to received NDEF messages. An NFC-enabled personal computer could, for example, open the web page that is provided in a Smart Poster NDEF message sent from an NFC-enabled mobile phone.
