RS232 cable or USB-RS232 adaptor
The development kit motherboard's USB socket provides ONLY power to the module. A RS232 connection is
required to have serial communications with the module on the carrier board. Laird provides a terminal
emulator program called Laird / EZURiO Terminal for AT mode operation but you can use your preferred
terminal emulator program in its place. Another program Laird provides is MpBtHost for multipoint (MP)
mode operation. This example uses the Microsoft Bluetooth stack and software that comes with Windows 7.
If your computer has built-in Bluetooth support, you can modify the computer aspect of the procedure
documented below to match your existing Bluetooth instead of using the supplied BRBLU03-010A0.

REPARATION
To prepare your setup, follow these steps:
1. Plug in the BT730 Carrier Board to the DVK motherboard.
NOTE: The carrier board plugs into 40-pin Hirose connector as shown in
