Connecting from Module to PC
To connect from the DVK-BT730 to the PC, open a second instance of Laird / EZURiO terminal using the
incoming computer COM port (COM32) noted in the previous step. In the example below, the first Laird /
EZURiO Terminal is connected to COM40 as an incoming port on PC and the second Laird / EZURiO Terminal
is connected to the module on COM 16.
The virtual incoming COM port (COM32) is waiting for an incoming connection, as the DCD indication is
deserted (

When ATD<Computer BT MAC address> is issued to the module, a SPP connection is initiated (
The 12 characters following the CONNECT message are the Bluetooth address of the PC BT module. The four
characters following the BT address indicate the UUID, where 1101 is Serial Port Profile.

A transparent data connection is now present. Any text entered into one Laird / EZURiO Terminal appears in
the other having been transmitted over the Bluetooth link between the DVK-BT730 modules and the PC.
