1.Introduction
1.1. GENERAL DESCRIPTION
The Bluetooth RS232 Mini Adapter is a Bluetooth* adapter for use with the RS232 serial interface and can
be connected to any piece of equipment equipped with this interface.
The adapter is fitted with a high performance rechargeable battery so an external power supply is not
required. This makes the adapter particularly suitable for use in mobile applications.
No driver installation is required and the adapter functions fully independently of the operating system
platform in use.
Whenever a Bluetooth connection is set up between two pieces of equipment, one device is always the
Master, and initiates the connection, and the other is the Slave. The new Bluetooth RS232 Mini Adapter
can be operated in both Master and in Slave modes, i.e. the Bluetooth RS232 Mini Adapter is able to
establish a connection with another Bluetooth device and does not have to wait passively for a request for
a connection from an external piece of equipment.
In either case, it is essential that the partner device supports the Bluetooth serial port profile.
The Bluetooth RS232 Adapter is operational in slave mode immediately upon switch-on. An easy-to-use
configuration programme is supplied with the adapter with which the user can configure the connection
parameters, e.g. the baud rate, of the Bluetooth RS232 Mini Adapter.
For systems which do not operate under the Windows operating system, it is also possible to configure the
adapter using AT commands.
The adapter is fitted with a high-performance Li-Ion rechargeable battery. In mobile applications, where
such factors as power consumption and operating time are of central importance, an automatic power
management function is available, which can be set to switch the device into energy saving mode ('Sniff'
mode). This leads to a considerable reduction in the power consumed by the partner device.
A further important feature here is that the adapter only goes into operational mode once a signal is
actually present on the serial interface. In other words, the adapter is only activated once the equipment to
which the Bluetooth RS232 Mini Adapter is connected has been switched on.
Our experience has shown that a great many demands are placed on Bluetooth solutions. For this reason,
the Bluetooth RS232 Mini Adapter has been conceived to be usable together with a large number of
solutions.
If the particular application you wish to run can not be implemented using the standard functions described
in this handbook, please be sure to see Chapter 6 – Special Functions.

The Bluetooth RS232 Mini Adapter is a completely new product and displays a whole host of exciting
functions. So as to avoid problems, we highly recommend that you read the instructions in this handbook
before putting the adapter into operation for the first time.

Whenever a Bluetooth connection is set up between two pieces of equipment, one device is always the
Master, and initiates the connection, and the other is the Slave. The new Bluetooth RS232 Mini Adapter
can be operated in both Master and in Slave modes, i.e. the Bluetooth RS232 Mini Adapter is able to
establish a connection with another Bluetooth device and does not have to wait passively for a request for
a connection from an external piece of equipment.
It is important that the partner device supports the Bluetooth serial port profile (SPP).
After the initial switch-on, the Bluetooth RS232 Mini Adapter is in standard Slave mode. It is then possible
to select between two further modes – normal operation and configuration mode.
In normal operation mode, a data connection to the Bluetooth Adapter is set up, whereas the
configuration mode is used to set the configuration of the Bluetooth Adapter via the Bluetooth connection
or serial interface.
The standard settings of the LinTech Bluetooth* RS232 Mini Adapter are as follows:
Baud rate : 115200 Bit/s
Stop bit : 1
Parity : None
Data bits : 8
Bluetooth* PIN : 1234
Please note that it is essential for the Bluetooth RS232 Mini Adapter to be the Bluetooth slave when the
adapter is put into operation for the first time.
To change the configuration via a Bluetooth connection, the adapter must be set to configuration mode and
a connection to an external Bluetooth device must exist (please see the relevant section of your handbook).
If you wish to set up a Bluetooth connection from another Bluetooth device to the Bluetooth RS232 Mini
Adapter without changing the configuration, please follow the instructions in the subsequent sections.
2.5. COUPLING PROCEDURE FOR CREATING A BLUETOOTH DATA CONNECTION
Setting up a Bluetooth connection requires any Bluetooth master that supports the Bluetooth serial port
profile. Please perform the coupling procedure as described in the following.
The first step is to initiate a device search using the Bluetooth* partner device (integrated Bluetooth* circuit,
USB dongle, PCMCIA card, or similar) in the Bluetooth environment.
Here you should find displayed 'LinTech RS232 MINI', indicating that the Bluetooth RS232 Mini Adapter
has been found.

2.6. SETTING UP A CONNECTION
For information on how to establish a connection using a serial facility, please consult the instructions
supplied with your Bluetooth equipment.
In most cases, the Bluetooth environment provides you with virtual COM ports. The Bluetooth* Serial Port
Profile must be allotted to one of these COM ports. It is via this COM port that you communicate with the
Bluetooth RS232 Mini Adapter .
3. Configuration
Configuration of the Bluetooth RS232 Mini Adapter can be performed either via an existing Bluetooth
connection or directly, by connecting it to a the serial interface of a PC.
Before performing the configuration, the Bluetooth Mini Adapter must be put into configuration mode (see
chapter 3.2)
3.1. STANDARD SETTINGS
The standard settings of the LinTech Bluetooth* RS232 Mini Adapter are as follows:
Baud rate : 115200 Bit/s
Stop bit : 1
Parity : None
Data bits : 8
Bluetooth* PIN : 1234

* Bluetooth and the Bluetooth logos are trademarks owned by Bluetooth SIG, Inc., U.S.A. and licensed to Lintech
GmbH, Berlin Germany. 11
An easy to use Windows programme is provided with which you can configure standard settings and also
access other features (such as activating SNIFF mode, connection properties, security settings etc.) either
via an existing Bluetooth connection or via the serial interface of the adapter (see chapters 3.2-3.4).
For all those applications for which no Windows application is available, it is possible to perform the
configuration by means of AT commands using any available terminal programme (chapter 3.5).
For configuration purposes, the LinTech RS232 Mini Adapter provides you with a special Bluetooth*
configuration programme. In other words, in addition to its normal operational mode, it is possible to use
the Bluetooth adapter for configuration purposes and for changing from one operational mode into this
configuration mode.
It is not necessary to remove the Bluetooth adapter from the device with which you are operating it before
performing the configuration.
For information on how to switch between the two modes, please see the following section.
3.2. CHANGING BETWEEN CONFIGURATION MODE AND NORMAL OPERATION
Press the button on the rear side of the Bluetooth Adapter briefly ( see Illust. 1).
LED2 will then flash continuously for about two seconds, following which LED2 flashes slowly in green for 3
seconds before changing to red.
When LED2 flashes slowly in red, it means that the adapter is currently in configuration mode.
The serial Bluetooth service COM-CONFIG is now available.
If you press the button again for a short time, the Bluetooth adapter will return to normal operation.
(LED2 again flashes continuously, after which LED2 flashes slowly in green).
When LED2 flashes slowly in green, it means that the adapter is currently in normal operational
mode.
The serial Bluetooth service COM-HARDWARE is now available.
3.3. CONNECTING TO THE CONFIGURATION SERVICE
To be able to configure the Bluetooth RS232 Mini Adapter via Bluetooth, it is first necessary connect the
Bluetooth partner device ( Master) with the Bluetooth RS232 Mini Adapter connection service.
To do this, a service determination procedure must be carried out in the Bluetooth manager of the
Bluetooth partner device. The Bluetooth RS232 Mini Adapter offers the COM-CONFIG service.
Connect up to this configuration service.
For information on performing this step, please consult the instruction manual supplied with your Bluetooth
partner device.

Illustration 9 ConfigTool configuration programme – connection parameters
Baud rate Selecting baud rate
The baud rate defines the speed at which the device is able to communicate.
It states the number of times per second that the signal level changes during a
connection. It is only equal to one bit per second when the respective signal
contains one bit of transmitted data
Modems, for instance, must operate at the same bit rate in order for them to
be able to communicate with each other.
User-defined baud rate It is possible to programme a user-defined baud rate, which can differ from the
baud rates stated in the standard settings
Please note: Technical operating conditions may require that inputted baud
rate values are rounded down.

* Bluetooth and the Bluetooth logos are trademarks owned by Bluetooth SIG, Inc., U.S.A. and licensed to Lintech
GmbH, Berlin Germany. 16
Parity Selecting parity for error correction
The parity test involves the addition of a parity bit, the purpose of which is to
maintain either an even or odd number of bits within a data packet that are set
to 1, according to requirements. The receiver adds 1 to the number of bits it
receives and then either accepts that data packet or rejects it, depending on
whether or not the sum corresponds with the parity bit.
Setting Purpose
Even The parity bit is set to either 0 or 1 so as to obtain an even number
of bits set to 1.
Odd The parity bit is set to either 0 or 1 so as to obtain an odd number of
bits set to 1.
None No parity bit transmitted.
Stop bits Selecting number of stop bits
Stop bits form the framework of the data packages in asynchronous
communication. This data informs the receiver that a byte has been
transmitted. Modern asynchronous protocols require a maximum of one stop
bit.
Deactivate automatic
handshake / force

Use Sniff mode When selected and the SNIFF is activated, communication is reduced to the
so-called SNIFF slots. As a result, the Bluetooth RS232 Mini Adapter
consumes less energy.
Please note that activation of the SNIFF mode results in a reduction in data
flow and an increase in latency time.
Idle time preceding
operation of Sniff mode This is a sliding control used to regulate the interval after which the device switches into the energy-saving SNIFF mode, when no data is being
transmitted. As soon as further data is transmitted, the R232 Mini Adapter
changes to active operational mode.
Note:
When the sliding control is set to OFF, the device no longer alternates
between active and Sniff modes. If the Use Sniff Mode switch is activated,
the RS232 Mini Adapter is always in Sniff mode.

3.6. CONFIGURATION USING AT COMMANDS
An additional method of configuring the Bluetooth RS232 Mini Adapter for setting the connection
parameters is to use AT commands.
This option is provided due to the fact that not all environments use Windows as an operating system. All
that is required on your RS232 Bluetooth Mini Adapter partner device, or the PC to which the adapter is
directly connected, is a terminal programme, (e.g. Hyperterminal).

* Bluetooth and the Bluetooth logos are trademarks owned by Bluetooth SIG, Inc., U.S.A. and licensed to Lintech
GmbH, Berlin Germany. 19
If you wish to configure the Bluetooth RS232 Mini Adapter via a Bluetooth connection, the Bluetooth device
must be connected to the Bluetooth RS232 Mini Adapter configuration service programme.
It is also possible to configure the adapter using AT commands by connecting directly to the serial interface
of a PC.
Either way, the Bluetooth RS232 Mini Adapter must be set to configuration mode. For instructions on how
to switch from normal mode to configuration mode please see chapter 3.2.
Start the Terminal programme.
Connect the Terminal programme to the Com port to which the COM-CONFIG service of the R232 Mini
Adapter is connected.
Select the following settings: baud rate 115200 Bit/s, 8 data bits, 1 stop bit, 1 start bit and no parity.
Once the connection has been successfully established, the terminal programme window will display a list
of available AT commands.
Should this listing not be displayed, please enter <ATI2>“ followed by <ENTER> . This will effect a repeat
display of the available commands.
A list of all the available commands is also contained in the following section. The respective commands
are entered in the terminal window; no echo is produced when the characters are inputted. After inputting a
command, it is always necessary to press <ENTER> .
Any changes made are implemented immediately and saved in the RS232 Mini Adapter.
3.6. SHORT LIST OF AT COMMANDS
Whenever a Bluetooth connection is set up between two pieces of equipment, one device is always the
Master, and initiates the connection, and the other is the Slave. The new Bluetooth RS232 Mini Adapter
can be operated in both Master and in Slave modes, i.e. the Bluetooth RS232 Mini Adapter is able to
establish a connection with another Bluetooth device and does not have to wait passively for a request for
a connection from an external piece of equipment.
The AT commands in the following table indicate whether they are suitable for use in Master or Slave mode
or, in the case of general AT commands (e.g. when reading firmware version information), if both modes
are applicable.
