INTRODUCTION
Congratulations on the purchase of your GigaWaveTech Bluetooth Serial Port Dongle GWT-
SPP1. The GWT-SPP1 is a plug and play adapter that allows you to easily add Bluetooth
wireless connectivity to the serial port of your equipment. In itself, the GWT-SPP1 does not
require installation of software or drivers on the host machine. The dongle does not initiate
communications, but simply acts as a substitute for a wired serial connection.
The adapter employs Bluetooth technology compliant to the BT 1.1 specifications and
consists of a transceiver operating in the 2.4 GHz range. The operating range of the GWT-
SPP1 has been tested to reach up to 50m in line-of-sight communication and up to 10m in
typical indoor environment. It provides link control functionality and supports operation within
a Bluetooth net in the slave mode. In the current release, it supports fixed interface baud
rate of 115.2kbps using 8-bit data with 1 start, 1 stop-bit and no parity.
This Users’ Guide shows you how to quickly install the dongle for communication with other
Bluetooth devices support serial port profile.
ACCESSORIES
Each GWT-SPP1 requires a 4.5V dc AC-DC adaptor as power source. In addition, a 9-pin
straight cable with a male connector at one end and a female connector at the other end is
supplied. This cable may be used when there is not enough space to directly connect the
GWT-SPP1 dongle to the serial port connector of a host PC or when poor wireless reception
is encountered and locating the dongle away from the PC is desirable.

INSTALLATION PROCEDURE
Connecting to a Host PC
To use the dongle to provide serial communication between other Bluetooth device and a
host PC:
1. The dongle serial port connector can be connected directly to the serial port of a
host PC. However, in situation where connection is difficult or better wireless
reception is desired by keeping the dongle away from the host PC, the serial
cable can be used.
2. Connect the male end of a serial cable to the dongle serial port.
3. Connect the other end of the serial cable to the host PC.
(Note: The dongle requires a dedicated serial port on the host PC. It cannot share a
port with an internal modem or other device)
4. Power up the dongle following the procedure outlined in Connecting to Power
Source.
5. The Host PC is ready to receive data from other Bluetooth devices through the
serial port with the serial port settings matching that of the GWT-SPP1. The
GWT-SPP1 has an interface configuration of baud rate 115.2kbps, using 8-bit
data with 1 start and 1 stop bit.
Connecting to Power Source
The AC-DC adaptor provides power to the GWT-SPP1 dongle. Use only a GWT-approved
power adaptor with output rated 4.5V DC and minimum current of 0.2 Ampere.
To connect the power source to the dongle:
1. Connect the DC out put of the AC-DC adaptor to the power port of the dongle
located at the side of it.
2. Connect the other end of the AC-DC adaptor to a wall outlet.
3. Switch on the wall outlet and checks that the green LED is lighted (see Using the
LEDs for more information).
TRANSFERRING DATA FROM OTHER BLUETOOTH DEVICES TO
HOST PC
The GWT-SPP1 dongle is shipped with a set of pre-configured parameters. The pre-
configured parameters are:
• Device Name
The default name is “GWT SPP Dongle”. This name will be presented to other
devices, which are trying to connect to it.
• RS-232 Interface Configuration
The fixed baud rate is 115.2kbps, using 8-bit data with 1 start and 1 stop bit. The
host PC must same matching serial port settings.
The GWT-SPP1 attached to the host PC can be used with other Bluetooth devices supporting
Bluetooth serial port profile (SPP) to transfer data between the two machines. Some possible
configurations are illustrated as shown below.

Host PC
The other Bluetooth devices can be a Bluetooth dongle supporting dev A role of the
Bluetooth serial port profile or any Bluetooth-certified RS-232, USB, or PCMCIA products or
mobile phone with built-in Bluetooth features.
NOTE: The following description is a typical usage scenario from the other Bluetooh device.
Refer to the manual that came with the other Bluetooth device for instructions on its
installation and operation.
Once the other device is installed, let it discover the GWT-SPP1 dongle.
NOTE: If there is more than one GWT-SPP1 dongle in the vicinity for it to discover, you may
want to note the Bluetooth device address of your dongle the product label.
Select the GWT-SPP1 dongle from the list of discovered devices by its name “GWT SPP Dongle”
(and when necessary checks the Bluetooth device address) and double-click it to initiate the process
of connecting to the dongle. The dongle provides the service "SPP Slave".
Double-click on the "SPP Slave" service icon and the local device will connect to the GWT-
SPP1 and set up the serial port service. At this instance, the green LED of the GWT-SPP1
will become fast flashing.
At the other Bluetooth device, make a note of the COM port number assigned to this serial
port service selected.
Data transfer can now begin between the other Bluetooth device using the virtual COM port
(at any baud setting up to 115.2kbps) and the PC hosting the GWT-SPP1 dongle.
USING THE LIGHT EMITTING DIODES (LEDS)
There are two LEDs on the GWT-SPP1. The status indications provided by these LEDs are
as follow:
Colour Indication Status
Red Flash No RS232 signal detected at the connector. Check
for proper connection.
Fast flash Dongle has on-going Bluetooth connection (busy).Green
Slow flash Dongle is operational and in Discoverable and
Connectable mode
USING THE PAIRING SWITCH
The Pairing Switch is located at the side of the GWT-SPP1. This switch is catered for future
firmware release that supports secured mode operation. For this current release, the Pairing
Switch functionality is not implemented.
