Connecting a BOE to a PC with a DBT-120
In this exercise we will step through the process of establishing a connection from an eb500
module inserted into a Board of Education (BOE) board to a PC that has a D-Link® DBT-
120 Bluetooth USB Adapter.
To perform this exercise, as documented, you will need a D-Link DBT-120, a Board of
Education board, and an eb500 module. If you are using any of the other supported Parallax
boards, you may need to make adjustments to this exercise.
On the PC, the DBT-120 Bluetooth Software associates a COM port for establishing a
connection from the PC to a remote Bluetooth device and a separate COM port for
connections that are established from a remote Bluetooth device to the PC. This exercise
demonstrates establishing a connection from a remote eb500 to the PC. When a remote
Bluetooth device establishes a connection with the PC, the connection is established with
the DBT-120 Bluetooth USB Adapter software running on the PC. To gain access to the
data, an application, such as HyperTerminal, must open the COM port associated with the
connection established from the remote device. In the Communications section, we will step
through this process.
The D-Link DBT-120 Bluetooth USB Adapter software must be fully installed prior to
establishing a connection. The PC settings shown in this exercise are based upon the
software provided with the D-Link DBT-120 Bluetooth USB Adapter.
Step 1: DBT-120 Setup
In this step we will attach the DBT-120 USB Adapter to the PC. The software for the
DBT-120 should already be setup.
1.
Connect the
DBT-120
to an available
USB port
on the PC, following the instructions
provided with the DBT-120 Bluetooth USB Adapter.
Step 2: Obtain the Bluetooth Address of the PC
In this step we will obtain the Bluetooth address of the DBT-120 USB Adapter
attached to the PC.
1.
