2.3 Software interface

The FC6000 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.
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 phonebook management in any language.

2.4 Memory configurations

2.5 Speaker independent Voice recognition

2.5.1 Voice Recognition principles

2.5.1.1 Description
VoCon 3200 V3.3 is NUANCE training-less speaker independent speech recognition algorithm.
Phonemes recognition: words are recognized without previous training Words models for a better precision, especially for digits recognition Continuous voice recognition: no need for blanks between words New words learning (Voice tags), speaker dependent speech recognition (100 Voice
tags, 2kbytes by Voice tag)
Noise robustness and accuracy in an automotive environment: engine, click-button
etc…
Highly accurate recognition
2.5.1.2 Operation
During a voice recognition process, "Feature Extraction" module decomposes the signal. The module "Search" looks for the equivalent text using the modules "G2P" and "Grammar to compile". These two modules are using the libraries "Acoustic Model", "Lexicon" and "Grammar". Module G2P ensures equivalence between the graphemes and the phonemes. For each language is associated an acoustic model ("Acoustic Model"), a grammar and a lexicon ("Grammar" and "Lexicon"). System feedback is realized by a screen display and/or sounds (synthesized voice, chime, pre-recorded voice prompts…). Operation is ended by a final action (phone number dialing, radio station tuning…).

2.5.2 Text To Speech (TTS)

Text to Speech (TTS) on FC6000 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.
It 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.
Please find below Voice Recognition and TTS languages available in FC6000:

Notes:
1
: To make sure 1V8 power source is off when FC6000 is off, a Pull down resistor can be placed on
1V8_ENABLE line. Minimum value of 10kΩ is advised.
2
: Because current spikes up to ~20mA can occur on RESET_EXT_N pin, it is advised to use an interface
transistor to drive the RESET_EXT_N pin.
3
: BOOTS can be directly driven by a MCU GPIO without special concern.

7 Use Cases

A. Bluetooth HFP & A2DP/AVRCP use cases overview:

a. Head Unit paired with Mobile phone

Handsfree telephony & Phonebook Synchronization
Connections Strategy
If the Host does not store the last synchronized phonebook, it is always available for the Host at Module start up. Right after HFP connection (which is initiated to the last connected device), it is possible to place an outgoing call if requested. Once HFP initialization has finished (end of SLC/Extended SLC), the Module starts the best phonebook synchronization method available on the phone. The Module alerts the Host that the updated phonebook with new entries is available, and ready to be displayed on the HMI.
If an incoming/outgoing call occurs during the phonebook synchronization process, depending on the method of phonebook synchronization which is used, the process is paused. Once the call is finished, the phonebook synchronization restarts from where it has been stopped, and the call history is updated. This is transparent for the end user.
Calls Management
For incoming calls, the Caller ID (received from phone via CLIP or CLCC) is sent to the Host to be displayed on the HMI.
HFP indicators such as signal level, battery level and network provider are forwarded to the Host to be displayed on the HMI. CIND/CIEV indicators or GSM AT Commands are used for this purpose.
Service Continuity
This feature handles the audio management of a call when the module is powered on/off:
- When the module is powered on, the module automatically connects HFP to the phone and establishes the communication ((e)SCO connection) through the speakers during the SLC.
- When the module is powered off, the module transfers the audio to the phone ((e)SCO disconnection) and disconnects the Bluetooth link.
This process ensures the Host to be immediately ready to start Handsfree usage.
DATASHEET FC6000 Confidential Information 42/52
Page 43
Three way calling / multiple calls management
Once a call is established, if a second incoming call occurs, here is how the Host should handle the HMI:
- Green button: takes the second incoming call as active, and put the first one on hold. Press green button again to switch between the two calls.
- Red button: hangs up the active call and takes the second one as active.
Full 3-way calling management (and multiparty calls) is optimized with phones supporting HFP1.5. Parrot supports up to 7 calls at the same time for conference calls purpose.
With phones supporting HFP1.0 only, there are gaps in the specification such as:
- When the user manages the calls from the phone interface, the phone does not always notify the Module.
- When the distant party who is on hold hangs up from its side.

b. Head Unit connected to Mobile phone and headset device

SCO forwarding feature (2 SCO)
The module is connected to a Headset and a phone at the same time. When requested by the user, the Module is able to forward audio from the phone to the Headset. Therefore, the communication is switched for privacy purpose. Two SCO channels are opened from the Module.
Description of the behavior:
- Incoming call:
o Pick up from the HMI will pick up the call and establish one (e)SCO with the
phone and one with the Headset.
o Hang up from the HMI will hang up the call and release the 2nd SCO.
- Outgoing call:
o Dialing from the HMI will place the call on the phone, and once the remote
party has picked up, one (e)SCO is established with the phone and one with the Headset.
o Hang up from the HMI will hang up the call and release the 2nd SCO.
A command is proposed on Parrot Module to handle the establishment of dual SCO, depending on user need.

c. Head Unit paired with two Mobile phones

Multi HFP Feature
Parrot has developed the “Multi - HFP”, which enables the Module to handle two Handsfree connections at the same time. This use case is useful for people having two mobile phones, or when two users are in the car.
The Module is running phonebook synchronization on both phones, and each phone has its own phonebook available for the Host (phonebooks are not merged).
HFP indicators are available for each phone. Description of the behavior:
- First example: two phones (P1 and P2) are connected to HFP service. The host can start dialing on P1, hang up call then start outgoing call on P2.
- Second example: the phone receives incoming call P1 on Module. After the end of the first call from P1 the phone P2 can receive incoming call.
The multi HFP does not manage the calls of two phones at the same time.

d. Audio Streaming and Handsfree working together

Audio Streaming from phone to Module (remotely controlled by the Module)
AVHFP Feature
Most phones now support both HFP and A2DP Source/AVRCP TG. The most difficult case is to correctly handle the AVHFP Feature (dual use of A2DP/AVRCP and HFP).
As there is no specification release by the Bluetooth SIG explaining how this multi-profile use case should operate, a whitepaper has been issued by the A/V Working Group (“Simultaneous Use of HFP, A2DP, And AVRCP Profiles”).
Basically, the Whitepaper states that the phone should handle the streaming restart management once the call is finished (this is the main concern today):
- Incoming call: the AG should handle the streaming management:
o Pause the streaming on incoming call. o Send to the HF the indicators (CIEV Call setup) o Then the HF picks up the call with ATA, communication/SCO is established o Once finished (from AG or HF), the AG should restart streaming from where it
has been paused.
- Outgoing call from HF (ATD): the AG should also handle this in the same manner.
Nevertheless, most phones do not correctly implement the Whitepaper, and the streaming does not always restart after the call. Parrot has developed a strategy that automatically re­launches streaming in this case.
Song information availability
According to the AVRCP version supported by the music player (can be a phone or a Bluetooth Music player), the Host is updated with the following information in order to update its HMI.
AVRCP TG 1.0 (Category 1 – Music Players):
- Mandatory commands:
o Play and stop.
- Optional Features:
o Enhanced control: Next, Previous, Pause, FF, FW (most of the
phones/Players supporting AVRCP1.0 support those commands).
DATASHEET FC6000 Confidential Information 46/52

o There are a lot of other features, but the phone/Bluetooth Music Players do
not implement these extended commands.
AVRCP CT 1.0 (Category 1 – Parrot Module):
- At least one command of the specification should be supported.
- Parrot has decided to implement the full Player Control (events send to the phone):
o Play, Pause, Stop, Next, Previous, Pause, FF, FW
AVRCP TG 1.3 (Category 1 – Music Players):
- Mandatory commands:
o Same perimeter as AVRCP TG 1.0.
- Optional Features:
o If the phone supports the Bluetooth SIG Vendor Unique Feature, only Title of
the Media is mandatory for Metadata. And Playback status and change of current track shall be supported in this case.
o Other important features for Metadata support are Name of the Artist, Name
of the Album, Genre...
AVRCP CT 1.3 (Category 2 – Parrot Module):
- Mandatory commands:
o Same perimeter as AVRCP CT 1.0.
- Parrot optional features implemented:
o Referring to the specification, all “List of Media Attributes” are supported to be
displayed on the car radio HMI.
AVRCP TG 1.4 (Category 1 – Music Players)4:
- Mandatory commands:
o Same perimeter as AVRCP TG 1.0.
- Optional Features:
o If the phone supports the Bluetooth SIG Vendor Unique Feature, only Title of
the Media is mandatory for Metadata. And Playback status and change of current track shall be supported in this case.
o Other important features for Metadata support are Name of the Artist, Name
of the Album, Genre...
AVRCP CT 1.4 (Category 2 – Parrot Module)5:
- Mandatory commands:
o Same perimeter as AVRCP CT 1.0.
- Parrot optional features implemented:
o Referring to the specification, all “List of Media Attributes” are supported to be
displayed on the car radio HMI.
According to the AVRCP version supported by the phone, the HMI should be implemented with information provided by the Module: Player status / Metadata for the current played song.
As member of AV Working Group, Parrot is involved with the development of those specifications.

Parrot Module is able to maintain two Bluetooth connections: one HFP to a phone (where the phonebook synchronization is running after connection) and the other one with an A2DP SRC Music Player. From the Module point of view, there are two users connected.
As stated with the Whitepaper, in this use case, the Module handles the AVHFP because the A2DP SRC is not the connected phone. If the Bluetooth Music Player supports AVRCP TG, Parrot alerts the HMI with Playback status and Metadata.

g. Head Unit paired with Mobile phone: Data transfer

Dial Up Networking: The Head Unit acts as data terminal with a connected gateway device, typically a mobile phone.
Multi Profile Use
Parrot handles multiple Bluetooth connections. On the same device, it is possible to set up both an HFP and a DUN connection.
According to the various Bluetooth implementations on phones, here is the description of what is possible (given no phone limitations):
- DUN only:
o In this case, the phone acts as a Gateway and the Module forwards the data
to the Host (Data Terminal).
- HFP and DUN:
o If an incoming call occurs during the data transfer, there are three behaviors:
The call is established and data transfer continues without bandwidth
diminution.
The call is established and data transfer is stopped (AG gives priority
to HFP feature).
The distant caller reaches the voice mail of the connected phone
(phone limitation).
o If an outgoing call is requested by the user, the behaviors above also apply.
Those behaviors are described, phone by phone in the Parrot Bluetooth Compatibility Matrix with all tested phones.

B. Head unit BT/UART software update

The firmware of Parrot modules can be updated in two different ways: by Bluetooth when paired with a Bluetooth-enabled laptop, or UART.
This is a very important feature of the Parrot Module. This ensures better Bluetooth Compatibility with new phones coming on the Market. Some of these new phones need to have a specific workaround when the Bluetooth specifications are not correctly implemented on the phone (i.e. non-generic Bluetooth management).
Moreover, a major software update can include a new feature/profile (such as AVRCP1.4 for instance) to give more compatibility or functionality to a car radio. This software update can immediately be flashed (by Bluetooth, UART...) into your product already out in the market.
After the update, user settings (paired devices, phonebooks...) are not erased. This process is transparent for the user.
Methods available
- Bluetooth
o Via SPP o Via FTP
- Via UART with a host CPU that send the data
DATASHEET FC6000 Confidential Information 51/52
Page 52
Secured update mechanism
The new software is copied into the flash Module’s memory but the previous software is not
affected by this copy. During this process, if an error occurs before the end of file transfer (Bluetooth disconnection, data transfer stopped…), the module will restart with the previous software version.
The checksum of the new software is included into this new software. If the new file is correctly written into the flash, when Module will reboots, the new checksum internally calculated is compared the checksum of this new software. If checksum are equals, the new file will overwrite the previous one. During this process, if power supply is turned off, the remaining data will be continuing to be written where it has been stopped at the next boot.
