Compliance to FCC US/CAN
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occ ur in a particu lar
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outle t on a circuit different from that to
which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY ADEUNIS RF
COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT.
RF Exposure Warning: During operation, the user may keep a minimum
separation distance of 20 cm with the RF devices.

Overview
RF62
The A
communications over a 150-meter range in the worldwide 2.45 GHz
frequency band.
Bluetooth class 1 dongle enables Bluetooth® compliant duplex
The A
RF62
dongle fully complies with the V2 Bluetooth® standard and air data
rate goes up to 723 kbps. Data exchange and set-up are only done through
an UART data port, under SPP or DUN profile. A miniature antenna is
integrated.
RF62
A
can be used in two modes: command mode and transparent mode. The
command mode is used to established Bluetooth communications and set/get
parameters. The transparent mode is used for data exchange.
The dongle converts data from a serial link into a Bluetooth
®
radio frame to
be sent to a similar piece of equipment. The communication is half-duplex.
The operating parameters of the Bluetooth dongle (serial link, Bluetooth
®
management…) can be fully updated through AT commands via the serial
link.
We recommend reading the “specification of the Bluetooth
+ EDR” document available at the www.bluetooth.com web site.

Dongle operating mode
Two operating modes are available:
- Command mode (usage of AT commands and SPP_CONFIG mode),
- Transparent mode (serial data are transmitted on radio link).
At power up, the dongle is in transparen t mode according to the registers
configuration. The boot time is about 1s.
Command mode
The command mode is used to read and update the dongle configuration
registers using AT commands.
In command mode, the radio is inhibited (reception and transmission),
excepted when using test command.
Entering command mode : issues on the serial link a A+++ sequence.
The sequence A+++ characters is accepted only if no character has been
seen before and after the A+++ sequence. Register (S214) defines the
silence duration.
Tips : if you are using a terminal (such as Hyperterm), you hav e to send the
A+++ sequence using a text file (first create a text file containing only the
A+++ characters, and then use in Hyperterm the command “Send text file”
in the “Transfer menu”)

Exiting command mode (return back in transceiver mode) : send the serial
command
ATO <cr>
Transparent mode
In transparent mode, data received from the se rial link are transmitted on
the radio link. When data are received on the radio link, these data are sent
on the serial link.
Remote control configuration
SPP_CONFIG mode is used to remotely configure the slave dongle through
the master dongle serial link.
ARF62
Bluetooth
DCE Dongle
Master
This is done, on master side, in 4 steps:
Activation of the SPP_CONFIG mode us ing the ATC1 command. When this
mode is activated, the command issued on the master will be ignored by the
master and transmitted to the slave by radio.
Slave configuration: send command to the slave using the Master serial link.
When the remote configuration is done, the master must sent an AT&W
command to the slave (the AT&W command is mandatory because the slave
reboots when the master leaves the SPP_CONFIG mode or when the RF link
is loosed).
Leaving of the SPP_CONFIG mode using the ATC0 command.

AT Commands
Description
AT commands are interpreted only when the dongle is in Command
mode.
Commands : are used to read and update the dongle parameters
A command starts with the 2 ASCII ‘AT’ characters . ‘AT’ means ‘Attention’
follow with one or several characters or other data.
Each command is ended with <cr> (carriage return).
In the same command, the time between 2 characters must be less than 10s.
Response : is sent back for each command on the serial link. The answer is:
• <cr><lf ‘OK’<cr><lf> (ASCII character 0x4F) for accepted
command (or OK command)
• <cr><lf ‘ERROR’<cr><lf> for error
• Specific string when specified
Set of commands
The SPP CONFIG column indicates whether the command is
available or not when the dongle is in SPP CONFIG mode (ATC1
command).

Register description
The register value could be updated using the ATSn=m<cr> command and
displayed using Aton?<cr> command.
At power-up, the previous dongle configuration is read from E2PROM (non
volatile) and stored in RAM. The registers are located in RAM, any
modification is performed in RA M: To save current register con figurations, it
is necessary to use the AT&W<cr> command (If not, the updated
parameters are lost in case of power shortage).
The registers are shared in 2 types: read only (R) or read/write (R/W)
