IrDA Data Specifications (SIR/MIR/FIR/VFIR)


This family of specifications provides the base on which all upper layer protocols and applications are built.  The Data specifications are required for any IrDA-enabled devices.
  • IrDA Physical Layer Specification v1.5.

    The IrDA Physical Layer Specification is intended to facilitate the point-to-point communication between electronic devices (e.g., computers and peripherals) using directed half duplex serial infrared communications links through free space. This document specifies the optical media interfaces forSerial Infrared (SIR) data transmission up to and including 115.2 kbit/s, 0.576Mbit/s, 1.152 Mbit/s, 4.0 Mbit/s, 16 Mbit/s and 96 Mbit/s. It specifies transmission characteristic including optical properties and framing details.

  • IrDA Link Access Protocol v1.1
    The IrDA Link Access Protocol (IrLAP) specification describes thefunctions, features, protocol and services for interconnection between computers at the data link layer (OSI layer 2). IrLAP manages the negotiation, establishment and maintenance of areliable data communication link between a pair of IrDA devices
  • IrDA Link Management Protocol v1.1
    IrDA Link Management(IrLMP) defines two components within this architecture: the Link Management Information Access Service (LM-IAS) and the Link Management Multiplexer(LM-MUX). The LM-IAS provides amechanism for exchanging information about participating devices and the services they offer. The LM-MUX provides services to both Link Management itself and to its service users at Link Service Access Points (LSAPs).
  • IrDA Tiny TP v1.1
    The Tiny TP protocol detailed in this document provides independent per channel flow controll  plus and segmentation and reassembly of data above the LM-MUX between peer application entities.

  • IrDA Link Access Protocol - Fast Connect
    The purpose of the IrLAP Fast Connect procedure is to provide a faster method of establishing an IrLAP connection in certain scenarios. This document describes a new faster method for discovering a device and establishing an IrLAP connection. This new procedure is not appropriate for all scenarios and use cases. It is intended for scenarios where the initiating device occupies a fixed location (fixed-point device). An example is a tollbooth on a road.

  • IrDA Minimal Protocol Implementation, IrDA Lite
    IrDA Lite is a set of ideas on how to reduce the complexity and code size of the IrDA protocols while maintaining the capability to communicate with existing IrDA devices. The intent of these ideas is to provide a method for devices with simple data communication needs to implement IrDA protocols with a minimum of complexity in a small amount of RAM and ROM.

  • IrDA Physical Layer Test and Measurement Guidelines
    This document is intended to assist developers and others by providing recommendations and examples of measurements to determine compliance to the IrDA Serial Infrared Physical Layer Specification and is intended to be used with it and companion document the Protocol Test Specification.
  • IrDA Protocol Layer Test and Measurement Guidelines
    The purpose of this specification is to define the minimum behaviors that should be required of a device in order to receive the IrDA logo. The testing process is a verification of the claims made on the Compliance Statement. This specification will focus on the Protocol implementation. IrDA believes that Testing to the Protocol is the most reliable means of assuring interoperability and compatibility between devices.
