What is Bluetooth Wireless Technology?
Bluetooth allows compatible portable and stationary communications devices to
communicate without using cables. The technology is based on a radio link that
offers fast and reliable transmission of voice and data information. It doesn't require a
line-of-sight connection in order to establish and maintain communication. The
Bluetooth wireless technology uses a globally available frequency range intended to
ensure communication compatibility worldwide. Bluetooth is available in mobile
phones, laptops, handheld computers, industrial devices, cars, and more.

How can I use my Serial –Bluetooth gateway?
Your gateway communicates with its host system using RS232, RS422, or RS485.
Once connected to its host system and configured, the gateway can communicate,
using Classic Bluetooth and/or Bluetooth low energy, with a wide range of other
Bluetooth enabled devices such as other gateways, mobile phones, handheld
computers and laptops.
Figure 1.The gateway connected to the controller communicates wirelessly with a
Bluetooth enabled Laptop.
The gateway can initiate as well as accept connections to and from other Bluetooth
devices. When initiating a connection to another device, the gateway acts as a client.
When accepting a connection from another device, the gateway acts as a server. In
most cases the gateway communicates with one Bluetooth device at a time, but it is
possible to simultaneously communicate with several Bluetooth devices.
Getting Started
Before using your gateway you must:
Install the gateway. For more information, see Installation section.
Configure the gateway. For more information, please read the Getting Started
section. It is also possible to use the Toolbox for easy test and configuration.

Installation
Before using the gateway it must be connected to its host system and it must be
connected to a power supply. This chapter describes how to install the gateway.

To reduce risk of electric shock, unplug the unit from any power source before
attempting to clean it.
Troubleshooting
This section lists some problems that you might encounter while using your Anybus
Wireless Bridge Serial - Bluetooth.
1. I cannot connect. The data I send to the gateway does not arrive at the remote
device.
oMake sure that you have connected power to your gateway. The LED
indicator should emit a green light when powered up, being ready to
send and receive data.
oYour gateway is not configured to use the same serial settings (e.g.
baud rate) as your host system. Use the Toolbox to set the correct baud
rate.
oYou have configured your gateway to act as a client but you have not
selected a server device to connect to. Select a server device using the
Toolbox.
oYour gateway is too far away from the selected server device. Move the
gateway closer to the server device.
oYou are not using the correct Bluetooth profile. Your gateway must be
configured to use the same profile as the device you want to
communicate with.
oThe remote device is not in connectable mode. If the server device is
another gateway use the Toolbox to set the device in connectable
mode. If the device is another Bluetooth device, consult the manual for
that device to set it in connectable mode.
oMake sure that the gateway is in transparent data mode (green light).
Make sure that the gateway is not in configuration mode (orange light).

oIf high security mode has been selected on one of the devices wanting
to communicate, the two devices have to be paired with each other.
Either disable security or perform pairing. Also, note that pairing is
automatic during a connection setup if it is needed.
2. The Bluetooth link between my gateway and my selected remote peer
disconnects.
oYour gateway is configured to disconnect if no data is received or sent
during a longer period of time. Use the Toolbox to disable the automatic
disconnect or change the value of the timer.
oYour gateway is too far away from the device it is communicating with.
Move the two devices closer to each other.
3. There is no color on the LED indicator.
oMake sure that power is connected to the gateway.
4. When I search for other devices using the Toolbox I cannot find the device I'm
searching for.
oThe remote device is too far away. Move it closer to your gateway.
oThe remote device is not in discoverable mode. If the remote device is
a gateway use the Toolbox to set it in discoverable mode. If the remote
device is another device, consult the manual of that device to set it in
discoverable mode.
