The software interface provides a high level command set, hiding the complexity of the
Bluetooth.
This software is based on the well-known AT commands. Some of these commands are
directly derived from the GSM 07.07 recommendations and the appropriate Bluetooth
profiles.
Some supplementary commands are used to manage Bluetooth related functions like device
pairing and connection management as well as the acoustic and speech recognition
functions.
AT Command List and Bluetooth AT Command Software Specification are available on
demand.
BLUES supports Unicode, which allows the management of accents and phonebook in any
language. The format of the exchange with the HOST is UTF8

3.6 Reset and supply sequence diagram
3.6.1 Switching ON
•
The signal “NRESET” on the host interface is forced to a logical zero value by host
until the supply voltage reached its nominal value.
During this phase no component on the module is supplied.
•
The host switches its signal “NRESET” to a logical one value allowing the module to
turn on its supply.
•
After 70 ms, the supply gets stabilized and then triggers the start of the ASIC
•
100ms is necessary for the ASIC to start and give execution to the embedded
software that will turn the module into a permanent “active mode”
3.6.2 Switching OFF
•
The host sends the "sleep” AT command
•
The ASIC disconnects any BT link
•
The ASIC sends the "sleep acknowledge" AT command allowing the host to switch
the reset to a zero logical value.
•
If the host activate the “NRESET” to zero for at least 5 us but no more than 4ms the
module will be reset.
•
The signal “NRESET” on the host interface is forced to a logical zero value by host
until the supply voltage reached its nominal value.
Note: Switching off is also possible during “active mode” by turning reset to “zero” during
500ms. This unexpected reset is not recommended because some BT devices may
abnormally behave if the BT link is not properly disconnected.

3.8.5 USB
Note: USB Routing:
• Maintain parallelism between USB differential signals with the trace spacing needed to achieve 90
ohms differential impedance i.e the separation between the two traces; D+, D-, shall be larger than
their distances towards the USB signal reference plane: 90 Ohms differential = 2 times 45 Ohms to
ground in series.
• Avoid 90° turns , use two 45° turns or an arc instead.
• Do not route USB traces under crystals, oscillators.
• Route high-speed USB signals using a minimum number of vias and corners (avoid changing layers with
high-speed traces as much as practical.)
• Stubs on high speed USB signals e.g.towards the pull-down resistors, should be avoided
• Verify with an impedance calculator or TDR that the trace spacing and the trace width used on the
specific board stack up to 90 ohms differential impedance. With low or minimal coupling between the
two traces; D+, D-, the characteristic impedance towards the USB signal reference is dominant and
shall be equal to 45 Ohm single ended.
• HIGH SPEED USB signal pair traces should be trace length matched. The maximum trace length
mismatch between HS USB signal pairs should be no greater than 200 mils.
• Ensure D+ and D- traces have grounded solid guard traces aside and a solid USB signal reference plane
underneath them from the USB connector up to the USB transceiver device.

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 Confidential Information 36/49
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.

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.

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 behaviour:
- 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.

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 Confidential Information 40/49
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.
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.

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. USB/iPod Use Cases
Parrot DISCO Library handles the USB/iPod/iPhone connectivity, and gives to the Host the
ability to manage the music player.
When it is allowed by the protocol, DISCO is able to build a database from the music files
available on the device.
o
USB mass storage, SDCards, local file system: a database can be created, called the BSM
Database ("Base de Synchronization Musicale": in French for historical reason).
o
MTP (Media Transfer Protocol) devices: a similar database can be created.
o
iPods/iPhone: if the device is seen as a USB mass storage device, a database can be
created, otherwise we use the iAP (iPod Accessory Protocol) protocol and no database is
created.

The iPhone/iPhone3G can be used as a Bluetooth AG and Music content at the same time.
In this case,
- First the user has to pair/connect its iPhone via Bluetooth to get the HFP features.
- Once HFP connection has been established, he can connect its iPhone to the
dedicated iPod connector, and the Module handles the browsing.
The user will have the Bluetooth HFP capacity and at the same time the possibility to browse
the iPod’s content.
Parrot releases more information about supported features in the Parrot Compatibility Matrix.

Parrot music Management
Once the USB stick is plugged in for the first time, the Module reads the USB stick content,
parses music files, and gives the Host the access to the file system. Once this first parsing is
finished, the Module reparses music files, one by one, and builds the database using the
Metadata included in each file. The database is built according to this new parsing.
The Parrot Module provides the same set of commands for USB or iPods devices. The
implementation on the Host side is generic.
HFP and USB use at the same time
If a USB stick is plugged in while an HFP connection is already established with a phone, this
case is handled in two separate processes. Handsfree features are available while DISCO is
building the database in the background, without altering the Bluetooth link.

C. Head unit BT/USB software update
The firmware of Parrot modules can be updated in four different ways: by Bluetooth when paired with
a
Bluetooth-enabled
laptop, by DUN, USB 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 work-a-round 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, USB...) 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
o Via DUN (through a mobile phone connected to a server where is stored the
new software)
- Via USB with a standard USB Stick.
- Via UART with a host CPU that send the data
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, USB Stick removed…), 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.
