7.0 Configure Bluetooth to Serial Adapter
This chapter explains how to configure the Bluetooth-to-Serial Adapter and pair it with a Bluetooth
USB Dongle. Please note that Bluetooth USB Dongle is NOT included in the package. We assume
that you have already installed Bluetooth USB Dongle and bound software in your PC successfully.
The following demonstration is the process of pairing steps with Microsoft embedded Bluetooth driver
on Windows XP Service Pack 2.
All the Bluetooth to Serial Adapter must be configured first before they can be used. The purpose of
configuration is to pair two Bluetooth devices for an exclusive connection between them, and pairing is
done by utilizing Bluetooth Address and PIN code.
After pairing process is done and power is on, Bluetooth to Serial Adapter will AUTOMATICALLY try to
link (Master) or to be linked (Slave) with another paired Bluetooth device wirelessly, just like there is a
cable connected between them.
There are two ways to configure your Bluetooth to Serial Adapter :
Local Setting Up
Remote Setting Up
7.1 Local Setting Up
Local setting up can be done by connecting a Bluetooth to Serial Adapter to your PC. You can connect
PC COM port to a Bluetooth to Serial Adapter directly or through a RS-232 converter cable as shown
in Appendix (page 28).
If you forgot any setting which was done before, local setting up is also the only way which allows you
to recreate the setting again.
7.1.1 Preparation :
Step 1 :
Connect this Bluetooth to Serial Adapter to your PC COM Port, such as COM1, COM2 or any other.
Step 2 :
Apply power to Bluetooth to Serial Adapter by using the accompanied 5V Power Adapter.

Step 3 :
Push the Mode Button until the MODE LED lights (Orange color), which indicates that the adapter
is in the Configuration Mode. In this mode, Bluetooth to Serial Adapter is working at Slave state which
is waiting to be linked with other Bluetooth devices.
Step 4 :
Launch Bluetooth to Serial Adapter Utility - CableReplacementTool2.exe in the accompanied CD
driver :
:\bluetooth\CableReplacementTool2.exe
Step 5 :
Select the PC COM Port which Bluetooth to Serial Adapter is connected.
If it is the first time you are configuring this Bluetooth to Serial Adapter, you can choose the default
Baud Rate : 115200.
Press Connect Button.
Local PC will use this baud rate to connect with your Bluetooth to Serial Adapter.
Note :
The connection will fail if wrong COM port is connected or Baud Rate settings is not correct.
Please refer to section 7.1.3 (page14) for more detail on baud rate setting.

7.1.2 Start Configuration :
Device Mode (default is slave )
Depending on the applications, there are two states which Bluetooth to Serial Adapter can operate in
DATA mode. They are Master and Slave states. If you are using a USB Bluetooth Dongle to pair with
a Bluetooth to Serial adapter, then Bluetooth to Serial Adapter can be set to either Master or Slave
state. If you are using two Bluetooth to Serial Adapter to pair together, then one of them shall be set to
Master and another shall be set to Slave.
Master - Trying to link with other Bluetooth devices.
Slave - Waiting to be linked with other Bluetooth devices.
Master state :
If you choose this state, then you must enter Bluetooth MAC Address of the remote Bluetooth device
(e.g. 000000000000) which this Bluetooth to Serial Adapter will be pairing and connecting with.
Default is none.
Note : Remote Bluetooth Address can be found by searching
your Bluetooth to Serial Adapter as shown in page 20.
Slave State : (Default)
Bluetooth to Serial Adapter can be found by searching
Bluetooth Device on PCs. If it is disabled, then it can not be
found. This feature will prevent other Bluetooth host or
devices to create a link with it accidentally if it has already
been configured to pair with another device before.
- 9 -

Discoverable (default is Enable )
If Discoverable is enabled, Bluetooth to Serial
Adapter can be found by searching Bluetooth Device
on PCs. If it is disabled, then it can not be found. This
feature will prevent other Bluetooth host or devices to
create a link with it accidentally if it has already been
configured to pair with another device before has
already been configured to pair with another device
before.
Auto ReConnect (default is Enable )
If Auto ReConnect is enabled, When Bluetooth to
Serial Adapter is broken it will auto reconnect , If
disable the Bluetooth will not auto reconnect.
Bluetooth to RS-232 adapter state
Local MAC Address :
The Bluetooth to RS-232 adapter MAC address
Local Device Pin code : (default is 0000 )
When you pair Bluetooth to RS-232 adapter you
need pin code for security.
Local Device Name : (default is Serial Adapter )
Enter a Device Name for your Bluetooth to Serial
Adapter (length <= 31 alphanumeric characters).
Remote Device MAC :
This MAC address for two Bluetooth to RS-232
adapter auto link each other. When you want one link
another , you should input another one MAC address
in this block then it will search this Bluetooth to RS-
232 that use this MAC address and auto link it.

7.1.3 More Detail on Initial Baud Rate Setting :
1). When power is applied to a Bluetooth to Serial
Adapter , it will try to link (Master) or be linked
(Slave) with another Bluetooth device with matched MAC address or PIN code. A link will finally be
built between them. If another Bluetooth device can not be found (e.g. its power is turned off), then
the initial baud rate of this Bluetooth to Serial
Adapter will be set to 115200 (default).
If you forgot any previous setting of Bluetooth to Serial
Adapter , and you want to reconfigure it. You
can turn off power of other Bluetooth devices, then power on your Bluetooth to Serial
Adapter
individually. At this moment, because it is impossible for your Bluetooth to Serial Adapter to establish
a link with its paired Bluetooth device (it is turned off), so the baud rate of the Bluetooth to Serial
Adapter is set to 115200 (default).
You can then use 115200 baud in advance step 2 of section 7.1.2 to connect Bluetooth to Serial
Adapter , with your PC, then change its settings accordingly.
2). When power is applied to a Bluetooth to Serial
Adapter , if its paired Bluetooth device is found and
automatic connection has been made between them (i.e. they are pairing connected), then the BLUE
Bluetooth LED on Bluetooth to Serial
Adapter will light up, and the baud rate of the Bluetooth to
Serial
Adapter will be the value which was previously input in UART Configure of section 7.1.2.
For your Bluetooth to Serial
Adapter , when its BLUE Bluetooth LED lights, and you want to local
set up your Bluetooth to Serial
Adapter , after entering into Configuration mode (both blue and
yellow LED light up now), you must remember this baud rate and use it to Connect with COM port
as mentioned in Step 5 of section 7.1.1.
3). When power is applied to a Bluetooth to Serial
Adapter , and a new baud rate is entered and saved
in UART Configure step. If you then push MODE button to get into DATA mode, then push MODE
button again to enter Configuration mode, baud rate will be the new one just entered.
