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.
