Step 3: Establish a Connection Using the DBT-120 Bluetooth Software
In this step we will establish a connection from the PC to the eb500 module inserted
into the Board of Education board.
The actions in this step need to be performed only once for the eb500. After
performing the actions in this step, the connection details will be stored on the PC.
Therefore, future connections can be established to an eb500 by simply opening the
associated COM port.
