Introduction
Getting Started
Operating your SkyeModule Nova begins with finding a method to connect to a host. The SkyeModule itself does
not operate without direction (commands) from a host. The host can be in the form of a PC or, more typically, an
embedded microcontroller. This document explains the physical and electrical characteristics of the module, so
you can understand how to integrate the Nova into a finished product.
For initial demonstration of the module, SkyeWare v4 software is available on the media that came with the
developer/evaluation kit or available for download at support.skyetek.com. Open this software on your windows
PC and it will be recognized when you connect through USB or RS232 (with developer kit interface board). The
software demonstrates features like selecting tags, reading and writing. It also has a powerful command builder
that lets you format, send and receive any command to and from the reader. More about SkyeWare can be found
in the SkyeWare User Guide. See the Additional Reading section below.
The next step after demonstrating the module’s functionality is developing your own communication with the
module. This can be achieved with simple code on a microcontroller or using the SkyeTek API on a PC. Once
connected to a host through one of the four host interfaces, the reader to host communication is formatted with a
full featured protocol called SkyeTek Protocol v3. In order to make learning commands and formatting easy, we
have developed a series of application notes with examples to get you started. The application notes start with
basic tag and reader commands and become very detailed for tags with special features. Read more about the
protocol and commands in section 12, Communicating with the Module and then move on to the Additional
Reading in section 1.3.
1.2
Why a SkyeTek Module?
Many customers may wonder, “What value does a module add over an RFID transceiver chip?”
RFID transceiver chips may seem simple, but they actually require significant engineering time and capital
investment to integrate. Transceiver chips contain up to 50 registers for configuration and functionality. In
addition, communicating over air protocols such as ISO18000-6C is complex, described in nearly 150 pages of
cryptic procedures. For example, just selecting a tag requires a minimum of 6 and up to 100 over air interactions
with multiple tags present. SkyeTek has also optimized the complex RF chain to give the best performance and
efficiency possible. SkyeTek modules mask the complexities of RFID from the user and pack functionality into
just a few commands.
SkyeTek’s core set of commands allow the user to read and write to tags with a single command, regardless of the
tag type. The module is also field upgradable, so you can use the latest security algorithms and tag features as they
are released. Power regulation and filtering for the radio are handled in the Nova, so you can supply voltage
directly from an unregulated source like a battery. Finally, the Nova will be modularly approved by the FCC and CE,
so you can bypass expensive radio testing at a certified test lab and avoid potential schedule delays due to failures.
Using a SkyeTek module will greatly reduce time to market and upfront development costs. Allow SkyeTek to
take the burden of developing an RF system so you can focus your energy on your core products.

EU Guidelines
The SkyeModule Nova was tested to the standards defined by ETSI 302 208-1 (Electromagnetic compatibility
and Radio spectrum Matters; Radio Frequency Identification Equipment operating in the band 865 MHz to 868
MHz with power levels up to 2 W).
In order to market and sell product in the European markets, manufacturers need to demonstrate compliance
using a Declaration of Conformity. Unlike the United States, there is no certification process through a regulating
body. Instead, manufacturers have the sole responsibility of ensuring their products are compliant to the
applicable directives and standards.
Also, unlike the USA and Canada, there are no “Modular Approval” rules under the ETSI standards, and the
integrator must either declare conformity of the entire system based on the testing of the module, or perform
additional testing with the complete integrated system including antenna(s). Since conducted testing was
performed with the module, it is straightforward to show compliance with a particular antenna based on its
radiation characteristics. Upon request, Skyetek will provide ETSI test data and reports as necessary to aid in
showing compliance to the ETSI standards when the Nova is integrated within the final product. Skyetek can also
provide it’s Declaration of Conformity (DoC), if requested. In addition, Skyetek engineers are available to assist in
EU compliance matters.
10 Host Interface Specifications
The SkyeModule Nova supports the following microcontroller host interfaces for easy integration into existing
systems:




USB (Overrides other interfaces when connected)
TTL Serial
SPI
IC
The SkyeModule Nova and the host interface board support TTL Serial and USB communications. The host
interface board provides a USB connector and a TTL to RS-232 level converter for the TTL Serial host interface. The
Host Interface system parameter determines which host interface is used for communication with the host.
Each interface is software selectable and only one host interface is active at a time, however, USB may
always be connected and overrides the current interface. The host interface is selected based on the

10.1 USB 2.0
As a USB device, the host detects the SkyeModule Nova as an HID device. The SkyeModule Nova uses a standard
HID driver but is not a certified USB device. The SkyeModule Nova supports both standard and high speed USB
hosts and enumerates correctly on both Windows and UNIX platforms. The USB interface is typically only used
for demonstration as a USB host controller is not usually available in embedded systems. To communicate with
the reader in USB mode, either SkyeTek (Skyeware) demonstration software or the SkyeTek APIs can be used.
See the SkyeTek support site for the latest software and API downloads at support.skyetek.com.
Figure 10-1 shows an example of a circuit to permit USB communications without using the host interface board.
Figure 10-1: USB Connection Diagram
NOTE – If powered by USB, the USB host must be capable of supplying the USB standard high power device,
500mA at 5V. Also, the Nova will always communicate via USB, when a USB host is connected.

10.2 TTL Serial
A two-wire serial connection (no handshaking) is provided on the TXD and RXD lines where TXD and RXD are from
the module's point of view. Data exchange between the host and the SkyeModule Nova occurs according to
SkyeTek Protocol v3 (ASCII or Binary mode). See more about the protocol in section 12, Communicating with
the Module.
Serial communication is the most common and robust host interface for this module in an embedded
system. Because the interface is asynchronous, the module responds immediately upon command
completion instead of waiting for a host clock as in SPI or I C.
Figure 10-2 shows a sample circuit that lets you connect the SkyeModule Nova without the host interface board.
This circuit uses an RS232 to TTL level converter to allow connection to a PC serial port. For direct connection to a
micro serial interface (using TTL/CMOS levels), simply connect directly to pins 49 and 51 of the Mini PCI express
connector. Figure 10-3 shows examples of typical communication on a signal level.

The protocol for retrieving the response data is outlined below:







The SkyeModule Nova is half duplex so the response data must be retrieved after the request has been
sent.
The GPIO3_DR (data ready) signal will transition high when data is available for the host.
If data ready is not implemented on the host, the host can poll the module starting 1ms after the
command send is complete. The module will respond with 0x00 when no data is present, and 0x02 (start
of frame) when data is available.
Response data will be thrown away if not read within 10 seconds of becoming available.
The MISO signal provides the response data from SkyeModule Nova to the host.
To retrieve data on the MISO line, the SSEL (Slave Select) signal must be low when the clock is sent for an
entire byte. Between bytes, SSEL can either stay low or transition high again as long as it transitions
low before the first clock of the next byte.
The host can use the data length field (response bytes 2 and 3) in order to determine how many
bytes to read from the module as these first bytes will always be present immediately following a
start of frame (0x02).
Figure 10-7 below shows the timing required to retrieve data on the MISO line.


The I C interface uses a standard two-wire connection in which SCL is the master clock and SDA is a
bidirectional serial data line.
The data packet exchange between the host (I C Master) and the Nova (I C Slave) uses SkyeTek Protocol
v3 (Binary Mode only). See more about the protocol in section 12, Communicating with the Module.
I C fast mode plus (1MHz), I C fast mode (400 kHz), and 100kHz data rates are all supported.
The data is sent and received MSB first.

The communication scheme from host to module is as follows:




Initiate a start condition (SDA transitions low while SCL is high).
Send the nine bits of the initial start packet as follows:
o Send the 7-bit address.
o Send a write bit as the eighth bit (0 for writing from the host to the slave).
o Send the ninth bit as the “acknowledge” bit (ACK)
o If the reader recognizes the address, it pulls SDA low to acknowledge
Use the bus to clock each byte of the SkyeTek protocol request.
After sending the entire request, initiate a stop condition. (SCL transitions high, and then SDA transitions
high while SCL is high)
Wait for command to complete:


The GPIO3_DR (data ready) signal will transition high when data is available for the host to read.
If data ready is not implemented on the host, the host can poll the module after the request is sent. The
module will NAK to a read while it is busy executing a command.
Communication scheme from module to host is as follows:






Initiate a start condition. (SDA transitions low, and then SCL transitions low.)
Send the nine bits of the initial start packet as follows:

o Send a read bit as the eighth bit (1 for reading from the slave to the host).
o Send the ninth bit as the “acknowledge” bit (ACK)
o If the reader recognizes the address, it pulls SDA low to acknowledge
o If the address isn’t recognized or the module is busy the SDA bit will remain high during the ACK
bit.
Clock each byte of the SkyeTek protocol response from the module.
After receiving the response, is received, initiate a stop condition. (SDA transitions high while SCL is high.)
SDA must transition while the clock is low and remain stable while the clock is high.
Response data will be thrown away if not read within 10 seconds of becoming available.
Recommended response handler method #1 (polling):




The SkyeModule Nova has 2 antenna ports to connect external antennas. The ports use an Ultra Miniature
Connector (U.FL) to save space and cost. Any 50 ohm antenna in the appropriate frequency band (865868MHz for Europe, 920-928MHz for North America) can be used with the Nova, however to maintain
compliance with FCC/IC regulations, we recommend using those (or similar type) antennas specified in
section 9 of this document in the USA and Canada.
The SkyeModule Nova also uses an advanced Adaptive Antenna Tuning circuit to ensure a quality impedance
match with any antenna. The user can take advantage of this feature by first attaching the antenna to the
port they would like to use, then sending a SkyeTek Protocol command to the Nova for it to execute its tuning
sequence. The Nova will measure the reflected power caused by impedance mismatch and t hen will
automatically compensate, delivering the maximum power to the antenna while reducing noise in the
system.
NOTE – Read range depends on antenna choice and operating environment. Range can vary widely, depending on
your choice of tag inlay and antenna gain.

12 Communicating with the Module
12.1 Host Communication (SkyeTek Protocol v3)
The SkyeModule Nova operates under control of a host according to SkyeTek Protocol v3. The basic
command and response formats are illustrated for your reference in the following two sections 12.2 and
12.3. The best way to get started creating and understanding commands is to follow the application
notes below while using the Protocol Builder in SkyeWare v4:


Nova Basic Tag Commands – Guides you through the select tag, read tag and write tag commands.
SkyeTek Protocol v3 Reader Commands – Explains how to read and write system parameters.
For more feature specific commands, use the tag specific application notes listed in the Additional
Reading section 1.3.
For a quick reference on the protocol if you already know the command you want to use, see the SkyeTek
Protocol v3 Reference Guide. This provides detailed information on each command structure, error
codes, and tags types. Be warned that this document is very lengthy as it details every command
available for every SkyeTek module.

13.2 Changing System Parameters
CAUTION – Changing system parameter values – especially the default values – can render your
SkyeModule Nova non-operational in your environment. Research, record, and test all planned
changes to make sure they are compatible with your system.
You can read or write system parameters via the following commands:




Read System Parameter – Reads the current value of the system parameter at the memory address
specified.
Write System Parameter – Writes a new value to the system parameter at the memory address specified.
Store Default System Parameter – Writes a new system parameter value to the non-volatile memory. This
saves the setting even after a power cycle or reset.
Retrieve Default System Parameter – Reads the system parameter value at the address specified out of
non-volatile memory.
See System Parameter Detail in section 13.3 for detailed information about individual parameters.
For full examples of how to use these commands, see the system parameter examples found in the Using
SkyeProtocol V3 Reader Commands application note.
CAUTION – Resetting (cycling power) on your SkyeModule Nova causes all system parameters to
revert to their default values. Any changes made to system parameters in memory are lost at reset
unless you write them to the non-volatile memory as the new default values. Any changes to the
default values do not take effect until the reader is reset.

14 Special Features
14.1 Sleep Modes
The Nova has two low power sleep modes: deep sleep (hardware controlled) and software sleep mode. The deep
sleep mode has the lowest power consumption but a longer wake time. It can only be set using the N_DEEP_SLEEP
pin 20 of the host interface connector. There is an internal pull-up on this pin, so if it is unused it can be left
floating. To put the reader into deep sleep, set this pin low. Software sleep mode can be set using the Operating
Mode system parameter. See the System Parameters section 13 for details. Current consumption and wake times
for both modes can be found in the Error! Reference source not found. section Error! Reference source not
found. and Error! Reference source not found. section Error! Reference source not found., respectively.
NOTE: SOFTWARE SLEEP MODE DOES NOT WORK IN USB COMMUNICATIONS. This is planned for future
firmware releases.
