Before using the BlueTool configuration programme, it is necessary that a Bluetooth connection exists to the
Bluetooth RS232 Mini Adapter which uses the configuration service of the Bluetooth RS232 Mini Adapter or a
physical connection to a serial interface on your PC.
For further information, please consult the BlueTool manual.
3.6. 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 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 via an existing Bluetooth connection, the Bluetooth
partner device must be connected to the configuration service of the Bluetooth RS232 Mini Adapter.
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 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 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 programme 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.
