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.
