Declaration of Conformity
Manufacturer’s name: ADEUNIS R.F.
Manufacturer’s address Parc Technologique PRE ROUX IV
38920 CROLLES - FRANCE
declares that the product if used and installed according to the user guide available on
our web site : www.adeunis-rf.com
Product Name: ARF32
Product Number(s): ARF7044A
is designed to comply with the RTTE Directive 99/5/EC:
EMC: according to the harmonized standard EN 301 489.
Safety: according to the standard EN 60950-1/2001
Radio: according to harmonized standard EN 300-328 covering essential radio
requirements of the RTTE directive.
Notes: - Conformity has been evaluated according to the procedure described in
Annex III of the RTTE directive.
- Receiver class (if applicable): 3.
According to the 1999/519/EC recommendation, minimum distance between the product
and the body could be required depending on the module integration.
Warning : - CE marking applies only to End Products: Because this equipment is only a
subassembly, conformity testing has been reduced (equipment has been design in
accordance to standards but full testing is impossible). Manufacturer of End Products,
based on such a solution, has to insure full conformity to be able to CE label marking.
- As the integration of a radio module requires wireless technological
knowledge, ADEUNIS RF proposes its technical proficiency to its customers for a precompliance qualification of end products. In case of no-conformity, ADEUNIS RF will not
be held back responsible if this stage has not been.

Overview
RF32
The A
over a 20-meter range in the worldwide 2.45 GHz frequency band.
The A
data rate goes up to 723 kbps. Data exchange and set-up are only done
through an UART data port, under SPP profile. A miniature antenna is
integrated.
A
module enables Bluetooth® compliant duplex communications
RF32
module fully complies with the V2.0 Bluetooth® standard and
RF32
can be used in two modes:
Classical Bluetooth® mode : Master starts with GAP identification, then,
SDAP profile review, SPP connection and transparent communication.

NOTE
For all I/Os :
Use of the Data Rate Jumper
The purpose of this jumper is to access the A
data rate in case of unknown UART parameters.
Data Rate Jumpe
It becomes possible to re-program the “Non volatile Settings” to access again
the ARF32 Module. When done, jumper can be removed.

module by forcing the UART
In case of setup error while evaluating,
communication with ARF32 module can be lost
(bad UART parameters setup).
By connecting the “Data Rate Jumper”, UART
settings are forced to :
• Data rate = 9600 bps
NB : other settings (Parity, Stop bit & Flow
control…) remain the same and have to be
check for recovery values..

If needed, ARF7044 modules may use a 2-mm pitch connector.
Usable references for mass production are:

Transparent mode
In this mode all the data received on the UART RX pin are sent by radio to
the target Bluetooth
module UART TX pin.
Mode selection
A specific command (transparent mode) is used in order to switch from
command mode to transparent mode.
A specific pattern : “UART break” is used to switch from transparent mode to
command mode.
Setting up a link using the command interface
Quick start using “Simply Blue Commander” SBC software (*) :
Connect one module with the RS232 link to a PC supporting SBC software.
Setup “SBC Configuration / Transport layer” at the current baudrate (default
9600), 8 bits, 1 stop, no parity, “Low level driver” & “CTS output flow control”
enabled.
Power up the two Bluetooth
< Rx: Event: SimplyBlue Ready, SW Version: 0212

> Click “BT environment inquiry” & “Send”
< All BT devices nearby send their own BDADDR & Class of Device
(SPP modules class of devices = 000000)
> Click “SPP link establishment”, replace FFs with slave BDADDR & “Send”
In bold : address of the target Bluetooth
< Target module will confirm the connection (State has to be 00)
> Click “Enter SPP transparent mode” & “Send”
< Target module will confirm entering transparent mode (State has to be 00)
You can now close SBC and use any kind of terminal software to exchange
data or files through the Bluetooth SPP link.

Final use with a PC terminal or a microcontroller
Power up the two Bluetooth
link to a PC or Notebook or PDA. Use a terminal software configured at the
current baudrate (9600 by default), 8 bits, 1 stop, no parity, flow control
material.
Please find below a typical request / response sequence in order to establish
a typical link. All requests must be sending by the PC / NB / PDA (i.e. the
master). All indication and confirm responses are sent by the Bluetooth
slave module:
