LinTech RS232 Bluetooth Mini Adapter
Introduction
General Description
The Bluetooth RS232 Mini Adapter/S is a Bluetooth* adapter for use with the RS232 serial interface and can be connected to any piece of equipment displaying this interface. The adapter is equipped with a high-performance rechargeable battery, so an external power source is not required. This makes the adapter particularly suitable in mobile applications. No driver installation is required and the adapter functions fully independently of the operating system platform in use.A Bluetooth connection between two devices is always in the form of a Master-Slave connection, i.e. one device always initiates the connection – this one is the Bluetooth Master device – e.g. PC/ Laptop or PDA with already integrated Bluetooth interface or with an Bluetooth USB Adapter, Bluetooth PCMCIA or other. To set up a Bluetooth* connection, you require such a Bluetooth* Master device that supports the Bluetooth* Serial Port Profile. After starting to search for Bluetooth devices, you will findthe LinTech RS232 Mini Adapter. From one PC/Laptop ,you can built up a connection to only one or to more Bluetooth RS232 Adapters/S´( max. 6 ). – Point-to-point or Point-to-multipoint- connection.
The Bluetooth RS232 Adapter/S is operational immediately upon switch-on. An easy-to-use configuration programme is supplied with the adapter with which the user can configure the connection parameters of the Bluetooth RS232 Mini Adapter/S, such as the baud rate, parity, quantity of data bits… For systems which do not operate under the Windows operating system, it is also possible to configure the adapter using AT commands. The device is fitted with a high-power LI rechargeable battery. In mobile applications, where power consumption and operating time are of central importance, an automatic power management function is available, which switches the device into energy saving mode (‘SNIFF’ mode). This results in a considerable reduction in power consumption by the partner device. A further important feature in this context is that the adapter really becomes operative when a signal is received at the serial interface. This means that the adapter is only in active mode once the device to which the Bluetooth RS232 Mini Adapter/S is connected has been switched on. Our experience has shown that a multitude of requirements are placed on Bluetooth solutions. For this reason, the Bluetooth RS232 Mini Adapter/S has been conceived to enable its use for a large number of solutions. If your individual application can not be implemented using the standard functions described in this handbook, please contact us.

If you want to modify settings, you have to switch the adapter to configuration mode. The Bluetooth RS232 Mini Adapter /S provides two services/ operating modes: Normal mode and Configuration mode. In Normal mode, a data connection is set up to the Bluetooth* Adapter; the Configuration mode is used to configure the settings for the Bluetooth* Adapter either via the Bluetooth connection or the serial interface. Before the configuration of the Bluetooth connection can be changed, the device must be switched to configuration mode, and a connection must exist to a Bluetooth device (for further information, please see the corresponding section of the manual).If you want to create a connection from another Bluetooth device to the RS232 Mini Adapter without changing the configuration, continue as outlined in the following sections.
The coupling process for setting up a Bluetooth data connection
To set up a Bluetooth* connection, you require a second Bluetooth* Master device that supports the Bluetooth* Serial Port Profile. Please perform the coupling procedure as outlined 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/S has been found.
Now initiate the coupling procedure.
The standard–PIN/ Bluetooth key for the
Bluetooth RS232 Mini Adapter/S is 1234.
Once the coupling procedure has been completed, the Bluetooth RS232 Mini Adapter/S offers a serial service by the name of COM-HARDWARE, using which you can connect the serial interface of the Bluetooth RS232 Mini Adapter/S with that of your equipment.
Setting up a connection
For information on how to establish a connection, 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/S .
Configuration
The Bluetooth RS232 Mini Adapter/S can be configured either via an existing Bluetooth connection or via direct connection to the serial interface of a PC. In either case, it is first of all necessary to switch the Bluetooth Mini Adapter from normal mode to configuration mode (see section 3.2.)
Standard settings
The standard configuration of the LinTech Bluetooth* RS232 Mini Adapter is as follows:
- Baud rate: 115200 Bit/s
- Stop bit: 1
- Parity: None
- Data bits: 8
- Bluetooth* PIN: 1234
An easy-to-use program is provided with which you can alter standard settings and also access other features (such as activating SNIFF mode, connection properties, security settings etc.) via an existing Bluetooth* connection or the serial interface of the adapter (see BlueTool manual).
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 (section 3.6).
For configuration purposes, the LinTech RS232 Mini Adapter provides you with a special Bluetooth* service. 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.
Changing between configuration mode and normal operation
Press the key on the rear side of the Bluetooth Adapter briefly ( see Ill. 1).\ LED2 will then flash continuously for about two seconds, following which LED2 flashes rapidly in short, green bursts for 3 seconds before changing to slow, short, red bursts. When LED2 flashes in slow, short, red bursts, it means that the adapter is currently in configuration mode. The serial Bluetooth service COM-CONFIG is now available. If you press the key again for a short time, the Bluetooth adapter will return to normal operation. (LED2 again flashes continuously, after which LED2 flashes slowly in short green light). When LED2 flashes slowly in short, green bursts, it means that the adapter is currently in normal operational mode.The serial Bluetooth service COM-HARDWARE is now available.
Connecting to the configuration service
To be able to configure the Bluetooth RS232 Mini Adapter/S via Bluetooth, it is first necessary connect the Bluetooth partner device ( Master) with the Bluetooth RS232 Mini Adapter/S configuration service.
To do this, it is necessary to perform a service determination procedure in the Bluetooth manager of the Bluetooth partner device. The Bluetooth RS232 Mini Adapter/S offers the service COM-CONFIG. Connect up to this service. For information on performing this step, please consult the instruction manual received with your Bluetooth partner device.
Connecting to the serial interface of the adapter – configuration using a physical serial interface
Once you have switched the Bluetooth RS232 Mini Adapter/S into configuration mode (section 3.2), plug the adapter into the serial interface of a personal computer.
Configuration using the LinTech BlueTool configuration programme
The LinTech RS232 BlueTool is an easy to use Windows configuration programme, with the aid of which you can perform all the settings required for the Bluetooth RS232 Mini Adapter/S easily and clearly.Please copy the programme from the cd supplied to a folder on your hard disc, and start the program from the hard disc.
- Before using the BlueTool configuration programme, it is necessary that a Bluetooth connection exists to the Bluetooth RS232 Mini Adapter/S which uses the configuration service of the Bluetooth RS232 Mini Adapter/S or a physical connection to a serial interface on your PC.
For further information, please consult the BlueTool manual.
Configuration using AT commands
In addition to the conventional method of using the BlueTool Windows configuration programme for configuring the Bluetooth RS232 Mini Adapter/S’s connection parameters, it is also possible to perform the settings using 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 is a terminal programme, e.g. Hyperterminal. If you wish to configure the Bluetooth RS232 Mini Adapter/S via an existing Bluetooth connection, the Bluetooth partner device must be connected to the configuration service of the Bluetooth RS232 Mini Adapter/S. It is however also possible to configure the adapter using AT commands, by connecting it directly to the serial interface of a PC. In either case, the Bluetooth RS232 Mini Adapter/S must be in configuration mode. For switching from normal mode to configuration mode, please consult the appropriate section of the manual (3.2) Start the Terminal programme. Connect the Terminal programme to the virtual Com port to which the COM-CONFIG service of the R232 Mini Adapter is connected (or to the COM port of the physical interface). 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 program window will display a list of available AT commands. Should this listing not be displayed, please enter <ATI2>“ followed by <CR> . This will effect a repeat display of the available commands. The respective commands are entered in the terminal window; no echo is produced when the characters are inputted. All command inputs must be acknowledge by pressing <CR> . All changes are implemented immediately and saved in the RS232 Mini Adapter.
