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. 

 
 
 
 

5.1. 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.
