you'll probably also want a class 1 (100-meter range) USB Dongle as the bluetooth chipset built into most laptops is not very good...


1)	Using a 4-pin header, solder the 4 middle pins on the bluetooth module to the CUI so that the
	VCC pin connects to the very top row (5V) on the CUI prototyping area
	
2)	connect the GND pin on the bluetooth module to GND on the CUI (easiest on the back)

3)	connect the TX pin on the bluetooth module to C7 on the CUI with a short wire

4)	connect the RX pin on the bluetooth module to C6 on the CUI with a short wire

5)	pair the Bluetooth module with your computer - open system preferences, click on 
	bluetooth, then click "set up new device", click continue, click "any device", continue,
	then select the "FireFly" device, and click next - when it asks for a passkey enter "1234".

6)	open Zterm or other terminal program and connect to the FireFly - it's LED should stop flashing and change to green.
	configure the Bluetooth module by typing the following commands:

FOR THE NEWEST BLUESMIRF GOLD MODULES you have to configure the baud rate of the bluetooth module once (it remembers after this) using a program like Zterm or just the command-line "screen" utility that's built into osx... enter these five commands in order - the first enters the command mode, the second sets the baud rate (to 921kBaud/sec), the third tells the module never to timeout for entering command mode (by default it has a timeout window, so if you're having trouble entering command mode, make sure to send the first commands not too long after turning it on), the fourth gives a new name to the module (you might need to re-pair the bluetooth device for the name to show up correctly), and the last exits the command mode.

7)	try out the firmware and corresponding max patch here  http://www.vrml.aau.dk/~dano/CUI_Bluetooth_4553.zip
	use the usual procedure for putting new firmware on the CUI... the source code is here:

8)	add a battery 3x AAA batteries work well, or a 4.2v Li-ion (careful with these) wired directly to a 5V point and GND on the CUI, or you can use batteries with higher voltages through the regulator on the CUI as labeled on the back side.  One last thing you might want to do is put a sticker or something non-conductive on the metal case of the bluetooth module so that it can't short out against 5V on the CUI.
