The HSDL-D100-001 and
HSDL-D100-002 comes with in
sub-assembly Printed Circuit
Board (PCB) module, while
the HSDL-D110-002 comes
complete in stylish mechanical
casing.

System Overview

Agilent IrDA Smart Dongles
are microcontroller-based
standalone system, complete
with standard embedded IrDA
protocol stack with IrOBEX
and support optional
application programs such as
the IrFM Profile, OBEX Server
and OBEX Client. Smart
Dongles handle IrDA
communication between
interfacing terminals
transparently, without the
need for constant host
supervision.

Smart Dongles are connected
to host terminals using 3-wire
Null-Modem serial interface.
The Serial Interface connection
is used for transferring data
as well as command and
control. The serial interface is
also used for firmware
updating from a connected PC
with the Smart Dongle Flash
Utility.

HSDL-D100-001 Smart Dongle

The HSDL-D100-001 Smart
Dongle uses a small form-
factor, single chip MCU
solution for basic standard
application such as data object
transfer using the IrOBEX
Profile. It comes with two
memory options: 2KB RAM +
32KB Flash (standard), and
4KB RAM + 64KB Flash
(optional). Figures 1 and 3
show the HSDL-D100-001
Smart Dongle System Block
Diagram and Software
Structure, respectively.

The HSDL-D100-001 software
supports core IrDA protocol
stack, IrOBEX, and basic host
serial interface software
module. Core IrDA protocol
stack handles low-level baud
rate negotiation, exchange of
connection configuration
parameters, data integrity
check, link management etc,
relieving host terminal from
such low-level IrDA
transaction.

This platform is equipped with
a 3-wire Serial Interface Port
(UART) for interfacing to a
host device. Table 1 and
Figure 2 show the pin
definitions for HSDL-D100-
001. TXD and RXD pins are
designed for direct connection
to UART port of host system.
Pin signals do not go through
a Level Shifter nor provide
RS-232 compliant voltage.

The power is supply from the
host system through the +3.3V
connector pin.

HSDL-D100-001 Smart Dongle
support a range of host
interface communication speed
(baud rate) from 9600bps to
115.2kbps.

Software Architecture for IrFM Application

The IrDA protocol stack is developed in layers, with API service for each layer of the infrared
communication protocols. Figure 7 shows an overview of IrFM customized Smart Dongle software
architecture. The IrFM software system consists of the following:

�

IrDA Port

The physical IrDA port provides a continuous, bidirectional communication up to 30 cm with
30degree half angle cone. Communication speed varies between 9600bps to 115.2kbps with the
data packet validation by software CRC-16.

�

Physical Driver

A set of low-level functions are provided to control and configure the hardware such as the
HSDL-3208 IrDA Transceiver, 16550 Compatible UART with ENDEC etc.

�

IrDA Base Protocol Layers

IrDA Base Protocol Layers consists of the following layers:

�

IrLAP

Provides a reliable device-to-device connection for reliable ordered transfer of data
between two IrDA devices. This protocol is a variant derived from the multi-drop HDLC
protocol that manage information exchange, connection/disconnection, resolve address
conflict, discovery to identify other devices and sniffing for devices to connect to.

�

LM-IAS

Maintains an information database for the IrDA device to identify itself to other IrDA
devices on the services it offers and looks for another compliant IrDA device as well.

�

LM-MUX

Provides multiple links over a single IrLAP.

�

TinyTP

TinyTP provides a flow control mechanism, segmentation and reassembly of data packets
for each transport connection created.

�

IrSock

This layer serves as an interface for higher layer application to access the underlying IrDA
protocol stack..

�

OBEX

Provides generic Object Exchange services to the application to support IrOBEX operations
such as CONNECT, PUT, GET, SETPATH, ABORT and DISCONNECT. This layer is required for
implementing the IrFM Point and Pay Profile.

�

Core IrFM Protocol (CIP)

Provides the IrFM Services with a set of primitives and corresponding data object that
conforms to the CIP specifications, for data to be exchanged between the POS and PTD
devices.

�

Applications (IrFM Service)

This layer provides IrFM services to user application.

IrFM Transaction Flow

Figure 11 illustrates a typical
the transaction flow for an
IrFM Transaction among the
Personal Trusted Device,
Smart Dongle and the POS/
CAT Terminal.

Sale transaction starts with
the POS initiates an IrFM
transaction with a customer's
PTD through the Smart Dongle
by sending the purchasing
amount to the Smart Dongle.

The Smart Dongle establish a
reliable IR connection, that is
capable of resuming a session
without the lost of data when
the underlying transport layer
(i.e. IrLAP Link) is temporary
broken. This is accomplished
by employing the OBEX
Session Protocol.

After a successful OBEX
Session has been setup, the
Smart Dongle and customer's
PTD complete the IrFM

transaction by using a set of
Core IrFM Service.

A soft copy of the digital
receipt is beamed to the
customer's PTD for verification
and tracking at the end of
IrFM transaction.
