4. Changing Settings

This device contains a comprehensive set of Bluetooth and COM port features which can be changed from an easy to use

“bulletin board” type configuration menu. This section gives full details about the changes that can be made, how to make

them, and the implications the changes will have on the manner in which your adapter behaves.

4.1. Configuration features at a glance

Below is a quick list of the configuration options that are available from the interactive menu. They will be covered in more

detail later in this section.

View/Set local COM port settings (baud rate, parity, stop bits)

View/Set Discoverability, Security mode and PIN number

View/Set Pairing options (including pairing to another adapter)

View/Set Client/Server configuration (Client connects to Server – important if “pairing” 2 adapters)

View/Set Local Device Name and Device Class

View all “factory” and modified settings plus local Bluetooth Address

Disable/enable configuration menu

Permanently update “factory” settings

Upgrade Device Firmware

4.2. Accessing the configuration menus

The adapters configuration menus are available at any time that there is no Bluetooth radio connection established with

another device (unless of course you have selected the option to disable the menu). As soon as a Bluetooth connection is

made, the data sent to the adapter will be sent over the radio link to the remote device. A short time after the Bluetooth

connection is broken, the configuration menu’ s become available again.

Sending a single “Carriage Return” character to the adapter while no Bluetooth connection exists will activate the initial

main menu.

The example given below to connect to the configuration menus is performed using HyperTerminal, a terminal

application that ships with Windows. If you are using a different operating system, you will need a similar “terminal” or “tty”

type application (e.g. minicom), which talks directly to a serial port in that operating system. If you are using a different

version of Windows, the specific steps to invoke and use the HyperTerminal application may be slightly different –

please refer to your operating system documentation if you need further help in this respect.

First, connect the adapter, along with a ‘null modem gender changer’, if you have the DTE version, to an available serial port on

your computer. In this example, the COM1 port on the PC has been used.

Ensure the power adapter is connected and switched on (the leftmost green LED on the adapter should light. Start

HyperTerminal by clicking “Start, All Programs, Accessories, Communications, HyperTerminal”. Create a new

HyperTerminal session connect to your COM port with the defaults of 115200, 8, none, 1, Hardware.
