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.

Bluetooth* PIN : 1234
Plug the adapter into the RS232 interface of the equipment it is to be operated with.
The Bluetooth RS232 Mini Adapter recognises if incoming signals are present at the serial interface, i.e. whether the equipment is switched on or off.
If the equipment is switched on, the Bluetooth RS232 Mini Adapter goes into operating mode, LED 2 flashes rapidly for approx. 3 seconds and then changes to a slowly flashing green. ( For LED sequences, please sea the overview in section 6.)
If the device is switched off, the Bluetooth Adapter remains in Standby mode. Should the RS232 Mini Adapter not switch into operational mode despite being switched on, please charge
the battery. (See 2.3) The Bluetooth Adapter can be operated during the charging process.
2.3. CHARGING THE BATTERY The Bluetooth RS232 Mini 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. The battery must be charged before the adapter is used for the first time.
To charge the battery, please use the battery charger supplied so as to avoid overcharging the battery or causing any technical faults, and connect it to the appropriate socket at the rear of the Bluetooth Rs232 Adapter ( see Illust.1) .
The status of the charging process is indicated by LED1 on the upper surface of the Bluetooth Adapter ( see Illust. 1)

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.

Illustration 4 Searching for device with the service-ID: COM-HARDWARE
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
10
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.

authentication/encryption function.
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.

15
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.
Stop bits
Deactivate automatic handshake / force software handshake
Setting
Even
Odd None No parity bit transmitted.
The parity bit is set to either 0 or 1 so as to obtain an even number of bits set to 1.
The parity bit is set to either 0 or 1 so as to obtain an odd number of bits set to 1.
Purpose
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. Automatic handshake recognition is deactivated when this box is checked. The handshake channels are no longer evaluated.

17
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
18
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.

22
A Bluetooth connection between 2 or several devices always constitutes a Master-Slave connection. The Master device is always the one that initialises the connection, i.e. the one that begins the device search, locates Bluetooth equipment and initiates the Pairing procedure. The standard setting is for the Bluetooth RS232 Mini Adapter to operate in Slave mode immediately after switch-on, which means that it awaits a request from the partner device to establish a connection.
There are many cases, however, in which it is necessary for the RS232 Mini Adapter itself to establish a connection, for instance, if the connection is interrupted for any reason. It is also generally more effective to initiate a connection from a central recording instrument to the partner devices, when the former is used to control the calibration of equipment or machines or for everyday data recording from such equipment.
The LinTech RS232 Mini Adapter can also be connected as a Master, which means that the Bluetooth R232 Mini Adapter is able to initiate a connection.
4.2 SETTING UP A CONNECTION FROM THE ADAPTER AS MASTER TO A KNOWN PARTNER DEVICE
This implies connection to a partner device with which the Bluetooth RS232 Mini Adapter has already been connected:
The LinTech RS232 Mini Adapter has already been operational in slave mode with a Bluetooth partner device and you now require that the RS232 Mini Adapter itself establishes the connection to this equipment. All that you need to do is to change the Bluetooth RS232 Mini Adapter from Slave to Master mode, since in this case the partner device is already known. For more information, see section 4.4. Changing
between Master and Slave modes ........
4.3. SETTING UP A CONNECTION AS MASTER TO AN UNKNOWN PARTNER DEVICE
The Bluetooth RS232 Mini Adapter can be programmed so that in future, it sets up a connection to an unknown, user-selected Bluetooth partner device.
Conditions: You must know the address of the Bluetooth partner device, with which you wish to establish the connection.
The partner device must support the Serial Port Profile according to Bluetooth* Specifications 1.1. In this case, you must first of all switch the Bluetooth RS232 Mini Adapter into configuration mode
set up a connection with the configuration service from any Bluetooth partner device and perform the settings for the connection to the future Bluetooth partner device (see also sections 3.2 – 3.6 ).
Please note: If the RS232 Mini Adapter is in Master mode, it will by default attempt to establish the connection using the PIN 1234.

If the future partner device requests a PIN for the connection, this can also be entered using the configuration programme.
4.4. CHANGING BETWEEN MASTER AND SLAVE MODES
Press the button at the rear of the Bluetooth RS232 Adapter to change easily between Master and Slave modes.
Press the button continuously for about 15 seconds. This is then followed by an LED sequence (red – green – orange) lasting about 2 seconds.
THEN:
The R232 Mini Adapter restarts and flashes red for approx. 3 seconds – the adapter is now in Master mode and it will attempt to create a connection to the partner device.
OR:
The R232 Mini Adapter restarts and flashes green for approx. 3 seconds – the adapter is now in slave mode and will accept any incoming connections.
4.5. NOTES REGARDING SETTING UP CONNECTION AS MASTER IN THE EVENT THAT THE PARTNER DEVICE DOES NOT REACT
When the RS232 Mini Adapter is configured as the Master, it will automatically attempt to create a connection to the configured or known partner device. If this connection fails, there may be several reasons. If the partner device is not switched on, the RS232 Mini Adapter changes to 'Master idle' mode. The LED2 then lights up orange. A new attempt at creating the connection can be initiated by pressing the button.
Note: The LinTech RS232 Mini Adapter can be configured to perform continual attempts at connecting to the partner device. This setting is recommended when the RS232 Mini Adapter is required to re-establish a connection which has broken down due to excessive distance. To do this, you can use either the LinTech R232 Mini Configtool or the respective AT command.
(AT+SCMC=1)

4.6. SETTING UP MASTER CONNECTION
To terminate an existing connection, press the button on the adapter briefly. To re-establish the connection, simply press the button again.
5. Special functions
5.1. Active device search and coupling with other Bluetooth equipment
The functionality of the Bluetooth RS232 Mini Adapter means that it can be used in variety of system environments and projects. In the previous sections of this handbook, it was described how the adapter operates in standard mode as a Slave with all Bluetooth partner devices that support the Serial Port Profile and how the Bluetooth Adapter can be configured to automatically set up a connection to other Bluetooth equipment, in the so called Master mode. The requirement in all cases for operating in Master mode was that the partner device is known.
However, now there is a special function available, with which the Bluetooth RS232 Mini Adapter can also perform an active device search for other Bluetooth devices and to set up a connection to these. The advantage of this special function is that it is controlled by use of AT commands ( in a manner similar to modem control ). This means that, unlike other standard available Bluetooth adapters, the LinTech Bluetooth RS232 Mini Adapter can be operated using equipment/PCs that run with a different operating system to Windows.
For instance, the LinTech RS232 Mini Adapter is able to initiate a device search, perform a coupling procedure and connect to the device thus located.
All that you require on your PC or other equipment, to which the RS232 Mini Adapter is connected, is a terminal programme ( e.g. Hyperterminal ), with the aid of which you can control the device search and connection setup using AT commands.
This special function must first be activated in slave and configuration modes using the AT command interpreter or the ConfigTool (AT+MCON=1)
To do this, the RS232 Mini Adapter must be in Master mode ( see section 4.4: Changing between Master and Slave operating modes). The RS232 Mini Adapter must be connected to the physical serial interface of a PC and the terminal
programme must be opened via its COM-Port. The connection parameters (baud rate, stop bit, etc. ...)
correspond to the settings in the RS232 Mini Adapter.
