1. INTRODUCTION AND OVERVIEW
BlueBee is Bluetooth wireless module from Cytron Technologies which is design to adapt the
form factor of XBee module. The pinout of BlueBee is compatible with XBEE which is
suitable for all kinds of microcontroller systems that have 3.3V power out. There are 2 modes
on BlueBee which are Transparent mode and AT mode. The baudrate of module may be set
using AT commands/mode.
The BlueBee module comes with an on-board antenna, the antenna provides better signal
quality. It acts like a transparent serial port, which works with a variety of Bluetooth adapter
and Bluetooth phone. BlueBee is compatible with XBEE starter kit, so you may use
SKXBEE-BOARD or Arduino-XBee shield for BlueBee communication. The BlueBee is
only slave module. Communication among two BlueBee is not possible.

6. HARDWARE INTERFACE
SKXBEE-Board or UC00A/B may use to enabling bluetooth wireless control. This section
will show BlueBee installation with SKXBEE-BOARD and UC00A/B for bluetooth wireless
communication.
6.1 Using SKXBEE-BOARD
This board is basically a USB to UART breakout board for XBee module. The 2mm female
header soldered on board allows user to plug in the XBEE module without soldering. Since
BlueBee is compatible with XBEE, user may use this board for Bluetooth wireless
communication.
■Plug BlueBee module onto SKXBEE-BOARD.
■Connect USB B Type to SKXBEE-BOARD and the other end to USB port of
computer or laptop. Computer/laptop will detect COM port for the 1st time using.
You may check the COM port at hardware device. For this example, the COM port
for BlueBee USB Serial port is COM50. Now you can start communicating with
BlueBee module, in AT mode or Trans mode.

6.2 Using UC00A/UC00B
UC00A/B is USB to UART converter. It used as computer standard interface, USB to
connect a device to a PC/laptop via UART/COM. The driver for UC00A/B need to install
before we can use it.
■Plug the BlueBee module onto XBEE Breakout board.
■Using female to female jumper wires, connect pin from XBEE Breakout board to
UC00A/B. The pins used are VCC, GND, Tx and Rx pin. Tx and Rx pins should be
cross connected between them. In other words, Tx pin of BlueBee should be
connected to Rx pin of UC00A/B and Rx pin of BlueBee should be connected to Tx
pin of UC00A/B.

■Ensure 3.3V is select on UC00B.
*Please ensure to select the correct voltage, else BlueBee will be damaged, same apply if
UC00A is used.
■Connect USB of UC00B into USB port of computer/laptop. Wait a minute for driver
devices detect the COM port. The COM port should be different with
SKXBEE-BOARD COM port.

7.0 AT COMMAND
BlueBee has 2 modes of operation which is AT mode and Transmit mode. User may send the
AT command to the module to set the control parameters and sent control order. AT
commands should end with “\r\n”. It means when programming is finish, user should add
terminator (“ENTER” or “\r\n”). The default baudrate in AT mode is 38400bps.

To set or inquire control parameter, user need to set up hardware interface refer to Section 6
“Hardware Interface”. User may use either SKXBEE-BOARD or UC00A/B and hypertrminal
application to set/inquire the control parameter.
BlueBee module need to set to AT mode shown as figure below. Status LED will blink with
slow blinking when BlueBee in AT mode.
Open and set up HyperTerminal. Bare in mind that the baud rate for AT mode is 38400 bps.

8.0 GETTING STARTED
BlueBee is a slave module, so communication among two BlueBee is not possible. It can
create Bluetooth wireless link other host/master device such as Bluetooth handphone,
SKKCA , computer with built-in Bluetooth, and others Bluetooth devices. This section will
show example communication of BlueBee between 2 computers and between computer and
microcontroller.
8.1 Communication between 2 computers
For this example, 2 computers named computer A and computer B will be used. Computer A
as a host to BlueBee and computer B as a host to Bluetooth USB dongle. BlueBee is using
SKXBEE-BOARD or UC00A/B to communicate with computer A and bluetooth dongle will
use BlueSoleil software to communicate with computer B.

Product User’s Manual – BlueBee
Setup for computer A:
■Set BlueBee to Trans mode . Status LED will blink with faster rate. In Trans mode,
the default baudrate is 9600 bps.
■Setup hardware installation refer to section 6. User may use either SKXBEE-BOARD
or UC00A/B.
■Open and setup HyperTerminal for Computer A. For this example, the COM Port for
BlueBee is COM50 and baud rate is 9600. The COM port may different with other
computer/laptop.
Setup for computer B:
User need Bluetooth USB dongle and BlueSoleil software to allow computer A communicate
with computer B via Bluetooth link. Install BlueSoleil software into PC/laptop
●Connect Bluetooth USB dongle into USB port.
●Turn on Bluetooth with display classic view . Bluetooth icon can be found at icon and
notification taskbar (right and bottom of computer).

●Now, double click on the Bluesoleil will start inquiring for available service or profile
offered by BlueBee. After some time (around 1 to 3 seconds) Bluetooth Serial Port
Service should be highlighted as shown in below figure.
●Double click on Bluetooth Serial Port Service. If everything is working perfectly, a
window will pop up showing the virtual COM port which is connected to computer B.
In this case, a COM49 has been created.
