5 Wi-Fi features and main scenarios (FC6050W)
The Parrot module can either be configured as a Wi-Fi Access Point (AP), a Wi-Fi
station (client) or can be used in ad-hoc mode. As an access point, up to 8 devices can
be connected simultaneously.
The host is responsible for:
• enabling/disabling Wi-Fi
• configuring the security level (WEP, WPA, WPA2), and associated passes
• retrieving network information as needed (example: which users are connected)
The FC6050W manages the Wi-Fi network according to the host commands.
Regardless, the FC6050W is responsible for:
• taking care of low-level networking tasks
• keeping the host informed of networking events
There are a lot of different possible use cases, you’ll find below an overview of the main ones. For
more details, please refer to the part 14

currently widely supported on the market.
PAN, personal area network
The mobile device supporting PAN-AP (access point) provides the data directly on Bluetooth
L2CAP layer in IP packets. The module acts as PAN-U (user).
NAD, network access device, optional feature
An external NAD can be integrated on the customer motherboard. Parrot module manages
Telephony, data call, SAP, Phonebook and messaging features of the NAD. All these
features are provided to the host using the same upper level commands. The Hardware
integration and monitoring are under the customer responsibility. NAD supplier choice shall
be jointly agreed with Parrot.

3G USB Dongle
Parrot currently supports over 200 3G dongles worldwide. Compatibility testing is done
continually to verify interoperability with new dongles on the market. Test teams are present
is in the US, Europe, Japan, Korea and China.
USB Tethering
As for DUN and PAN, the device acts as a modem and provides the data to the module over
USB. Feature availability is provider and OS dependant. Parrot currently supports Android,
iOS, RIM and Symbian OS.
Wi-Fi Tethering
Any mobile device supporting Wi-Fi access point feature can be used by Parrot module as
an additional internet source. This feature has to be enabled by the network provider.
6.2
Parrot router
In order to provide flexible network handling and configuration, Parrot developed a router
embedded on the FC6050.
It allows the host to connect any network interface available on the FC6050 (Wi-Fi, 3G
modem, DUN/PAN via BT, Tethering over USB, HOST). It is configurable through a user
friendly set of AT commands (Parrot’s HSTI) and makes it possible to enable internet
services (ftp, vnc, http, for example) on each interface.
:
6.3
Miscellaneous
The FC6050W needs to be informed of the provider’s DNS (Domain Name Server) IP
address. This information is transmitted to the FC6050W via an HSTI command.
Parrot's FC6050W does not do filtering (firewalling) on the host provided network
transactions, except what may be needed for its own safety. Hence, if some filtering must be
done for network operator or any other reason, it shall be done by the host. Thus, the host is
responsible for the incoming network traffic. Examples include blocking incoming
connections, restricting use to http and https protocols, forbidding POP/IMAP use, blocking
VOIP etc. (these examples come from common phone operator contractual regulations).

7 Host to FC6050B/W interface details
The architecture relies on 4 key features:
1. Using USB as a fast, standard physical medium – USB is used to exchange
commands, events, and user data between the host and Parrot's Wi-Fi enabled
FC6050W. A USB 2.0 High Speed link has a bandwidth of 480 Megabits per second
(60 Megabytes per second). Even with upper layer protocol overhead needed by the
USB physical medium, there is more than enough room for a quality network
connection. [As a point of reference, a typical PC network interface card (NIC) is
100Mbs. A full-blown heavy duty network server has 1000Mbs (1Giga bit per second)
NICs.]
2. Standard networking over USB protocols - Just as serial lines have been used as
the physical medium for networking for years (reference Point-to-Point Protocol), USB
can be used as the physical medium for standard TCP/IP networking. CDC ECM
(Communication Device Class, Ethernet Control Model) is the USB - Implementers
Forum standard for such use. Using such protocols, the USB connection appears to
the operating system as a Network Interface Card (NIC), ready to carry Ethernet
frames. From then on, all rich TCP/IP protocol stacks are available.
3. Parrot's HSTI library uses networking as its logical medium - The Parrot Host
Software Interface (HSTI) library (see section 8) uses a network socket interface,
allowing command and event communication as on a network.
4. An inner, user-hidden network – This connection simply consists of just two nodes:
• the host processor
• Parrot’s Wi-Fi enabled OEM module.
The car information and entertainment system can be referred to as the host, and
Parrot's FC6050W module as the target. However, from a USB bus perspective (i.e.
according to USB standard terminology):
• the host is considered a “USB device”
• the Parrot's FC6050W target module is considered a “USB host”
The USB terminology of “USB host” and “USB device” does not interfere with the notion
of master / slave from a system perspective, but rather is a matter of hardware and
operating system stack configuration.
The networking architecture can be done using FC6050W as an USB device, and the
host as the USB host. However, in such a case, the use of USB media devices (for
example, MTP or USB flash drive with media files) cannot be done by the FC6050W,
even if a USB hub is used.
7.1
UART
Alternatively, if no USB port is available on the Host side, a serial port can be used to
control the FC6050 using Parrot’s HSTI command and control interface over UART.
DATASHEET Confidential Information 16/84
Ref: EL-
2009-009
7.2
Protocols used
Two types of protocols are used:
1. Standard networking over USB protocol, carrying both HTSI and internet data.
2. The Parrot's HSTI command and events protocol.
7.3
Standard networking over USB protocol for data transmission
The FC6050W handles a USB protocol named CDC ECM (Communication Device
Class, Ethernet Control Model) for networking over USB.
CDC ECM is the USB-Implementers Forum SIG standard for networking Ethernet over
USB. Widely used for cable DSL modem and USB-Ethernet dongles before the domestic
use of NIC became widespread, it has been an official part of the Linux OS since 2003.
CDC ECM goal is to use a USB connection to mimic NICs cards between a USB host
and a USB device, with their MAC and configurable IP addresses, able to convey any
Ethernet frames. These NICs can then be set up and used as any regular network card
would be. From a Linux application point of view, there isn’t any difference between a
USB CDC ECM network connection and a regular one. Actually, the Linux application is
not even aware of physical media used (USB rather Ethernet), since this media is hidden
behind the networking stack of the Linux OS.
RNDIS (Remote Network Driver Interface Specification) is Microsoft vendor-specific,
non-standard way to carry Ethernet over USB. Although RNDIS is not recommended,
RNDIS may be used as a replacement for CDC ECM.
8 Software interface, HSTI Library
The FC6050x software interface, HSTI Library, is defined by a high level command set
on top of Parrot Libraries.
This interface software is based on the HSTI commands defined by Parrot. These
commands are fully documented and the software library is provided by Parrot for easy
implementation in the host CPU.
Some commands are used to manage Bluetooth related functions like device pairing and
connection management as well as the acoustic and speech recognition functions.
Other commands are used to manage Music connected on USB ports.
The HSTI Command List and Bluetooth AT Command Software Specification are
available upon request.
The Bluetooth software stack, BLUES, supports Unicode, which allows the management
of language accents and allows for phonebook management in any language.

Parrot’s HSTI protocol for network connectivity
HSTI is Parrot's standard API used over its product range. It provides a rich yet simple,
fully documented set of more than 250 high-level commands to pilot the FC6050. The
host sends AT commands, and registers to events to be notified of changes occurring in
the FC6050.
HSTI is available and used on Linux operating system.
HSTI can be used over a network socket or a serial line (UART).
Some HSTI commands are specifically designed to handle network connectivity. For
examples, see the document “Parrot Host Software Interface Specification”. Some
networking commands are exemplified below.
The following steps are required in order for the host CPU to establish a dialog and take
command of the FC6050;
1. Setup the USB link to FC6050 as CDC ECM.
2. Configure this new Ethernet interface (IP address, netmask, broadcast address). For
ease of use, and since there is no added value in making these parameters dynamic,
these IP parameters should be fixed in the product (example 192.168.64.1) - to be
discussed with Parrot.
3. In the host application, open a standard internet socket. This socket will be used to
communicate with the FC6050 via HSTI. The port used for this socket should be a
fixed one, that does not interfere with any commonly used protocol (example value:
23000) – to be discussed with Parrot. From this point, regarding communication to
the FC6050, the host application will not have to care about networking any more.
The socket and USB network connection will be used transparently between the 2
CPUs to carry all HSTI dialog.
4. Register to HSTI events for notification. Events can either be responses from FC6050
to explicit host commands, or unsolicited, asynchronous events such as “new USB
stick insertion”, or “3G dongle insertion”.
5. The host can then send commands to the FC6050 using the HSTI API.
Regarding networking, some additional steps are required. As an example, if the internet
connectivity comes from a 3G dongle plugged into the FC6050 (see section 4, scenario
2):
• The FC6050 shall notify the host of the availability of the 3G dongle by sending an
event.
• If the host decides to enable the internet connection, it prompts the user, for the PIN
code. The prompt and PIN entry is done through the host user interface (screen and
keyboard or touch screen).
• The host sends the PIN code to the FC6050, via an HSTI command.
• The FC6050 manages the 3G dongle, and reports connection status to the host
(example: connection established, or PIN code rejected)

Some things to notice:
• The host may choose to make the internet connection available to the FC6050 Wi-Fi
access point or not. In all cases, the host is in command to dynamically enable or
disable capabilities via the FC6050.
• If the internet connectivity comes from the host (section 4, scenario 1), then the DNS
IP address has to be sent to the FC6050, using the dedicated HSTI command.
• If the host requires internet connectivity for itself from the FC6050 (section 4, third
scenario), then it should do so explicitly and query the FC6050 for the DNS address,
again using the dedicated HSTI commands.
• Internet connectivity provided by the FC6050 (second and third use case) is not “all or
nothing”. It can be used for;
o Wi-Fi access point only
o host only
o both Wi-Fi access point and host use
o disabled
In all relevant cases, the internet networking traffic between the host and the FC6050 will
use the same network interface established before via USB CDC ECM to carry HSTI
commands. This is done transparently so that applications, either on host or on the
FC6050, do not need to handle it (unless of course the host application is willing to do
so).
As a benefit inherited from its rooted serial line interface, the network traffic generated by
the HSTI dialog is extremely low: a typical HSTI query or reply ends up in a dozen or
less bytes of payload. Thus, this HSTI traffic does not interfere with the network
bandwidth available to Wi-Fi users or the host.
Here is an example demonstrating a typical host-side HSTI sequence to setup Wi-Fi,
choose a security level and setup a Wi-Fi network name:
/* set the Wi-Fi “on”, Access Point mode : */
HSTI_CmdAPI_Send_WSWM(AP);
/* Send access point configuration : set the security protocol to WPA */
HSTI_CmdAPI_SendWAPC(SET, SECURITY, WPA);
/* Access point configuration : the SSID naming the Wi-Fi network is “my car network” */
HSTI_CmdAPI_SendWAPC_STR(SET, SSID, “my car network”);

10.2
Text To Speech (TTS)
Text to Speech (TTS) on FC6050B & FC6050W is based on SVOX Automotive Speech.
SVOX Automotive TTS solutions are tailored for noisy car environments and enjoy a
reputation for industry-leading quality. They power many of the most advanced and
successful in-dash infotainment systems in the market. SVOX TTS technology is
characterized by natural and clear sound as well as unique polyglot capability – the
same voice can speak multiple languages like a native speaker.
SVOX TTS is not limited in vocabulary. It can be used to confirm the orders identified by
a voice recognition process or for reading vehicle commands, songs titles or phonebook
entries.
Abbreviations, tags, symbols (emoticons) are converted into readable text (grapheme-tographeme conversion). In addition, the SVOX TTS engine contains an advanced text
pre-processor that automatically handles common specifications for date and time.
SVOX provides an excellent quality prosody (i.e. sentence intonation) using state-of-theart prosody modelling technology. Accent values, phrase types, and phrase boundary
positions are taken into account for the determination of the speech melody (pitch
contour) and sound durations.

Voice Recognition for Music Data on external sources
10.4.1 RAP
RAP is an optional Parrot-developed voice recognition gateway. In combination with the
voice recognition option and the CONCERTOS software option it provides the user the
ability to select music on multiple external sources and to operate player functionalities
by voice commands. RAP allows recognition by album title, music type (genre) or artist
name regardless of where the media file resides.
The voice recognition latency is, on average, 1.8 seconds for a database size of 20,000
Albums or Artists. The latency can be improved by reducing the number of Albums or
Artists (~1s for 10 000). Based on trials with the French Parrot test database the voice
recognition accuracy is ~ 85 %.
The maximum number of recognizable items depends on the available memory.
10.4.2 Gracenote® for Music Data on external sources
Gracenote's technology is being relied on by many of the world's leading consumer
electronic devices and media software applications. Gracenote uses a multi-step
recognition method to enable identification, categorization, and organization of digital
music. Regardless of source or format, Gracenote gives music fans the tools to manage
and enjoy their music collections.
10.4.2.1 MediaVOCS TM
MediaVOCS, provided by Gracenote, is an advanced speech-based media database.
This database includes phonetic transcriptions for alternate artist, album and track
names. Even common names are often multiethnic, abbreviated or nicknames which
cannot be recognized by a standard voice recognition database. Based on Parrot
studies, adding Gracenote MediaVOCS to the voice recognition improves the recognition
rate by a factor of 33% on artist names and 16% on album names.
Gracenote MediaVOCS is available in the following languages:
US English
UK English
French
Italian

10.4.2.2 Playlist Plus
Parrot also offers an additional tool from Gracenote known as Playlist PlusTM. Designed
to work with MediaVOCS, Playlist Plus analyzes the metadata for music brought into the
vehicle and offers a variety of playlists for the music library. These playlists may be
either pre-set or user customized. In addition, the user may select “More Like This” and
hear other songs in the music library of a similar genre to the song currently playing.
10.4.3 Natural Language Understanding (NLU)
The Parrot FC6XX0 product line offers an advanced voice recognition system based on
Grammar based NLU (Natural Language Understanding, VoCon3200 version 3.3 )
With NLU, the user has the ability to control various vehicle feature by voice without
"being constrained" by traditional voice recognition menu trees or categories (music,
phone book, ...).
All Parrot features and other vehicle functions can be controlled via voice from the press
of a single “push-to-talk” (PTT) button.
With NLU, the user can skip the step of narrowing the choices:
• Selection of Phone Number from Phonebook
• “I want to call John Smith”
• “Call John Smith”
• “Call John Smith at home”
• “Call Smith at the office”
• “Call John Smith on Mobile
• Selection of Music from Music Library
• “Play something from John Mayer”
• “Play Parachutes from Coldplay”
• “Play Bob Marley” [Note: this command works even though the official artist name is
“Bob Marley and the Whalers”]
• “Play Jazz”
• “Play Alternative”
• “Play Super Hits of Miles Davis
These are just a sample of what is possible with NLU.
Other features, not residing on the Parrot FC6XX0 module can also benefit from NLU.
This includes use cases such as tuning of a radio station or activating a rear-camera
image:
• “Tune to 97.1 Megahertz”
• “Tune to 950 AM”
• “Switch to FM”
• “Seek”
• “Play AM preset 3

The Parrot RAP multimedia library option includes Nuance Music Pre-Processor (MPP)
to facilitate flexible voice recognition access to music. Specifically, Nuance MPP allows
the user to speak only a portion of the album title or artist name and find the intended
song. Flexible music selection allows users to speak the most common variations and
still be understood.
“Avia” for “Avia feat. Raz Ohara”
“Nuage” for “Nuage (Take 2)”
“Police” for “The Police”
With Nuance MPP, users can speak album titles are artist’s names that they know are
present on their own music player without looking at any visual prompt.
10.4.3.2 ddG2P / CLC MP3
Nuance ddG2P MP3 and CLC MP3 are Nuance’s high speed, small footprint
Graphemes to Phonemes converters (G2P, converting the text to phonetics) dedicated
to the music domain.
