1 What is Bluetooth?
Page 5 / 
1 What is Bluetooth?
1.1 Features of Bluetooth
Objectives of Bluetooth : To Realize Wireless Communication for Short Distance with Low Power
Consumption, High Reliability, and Low Cost.
Frequency in Use: To Use ISM(Industrial, Scientific, Medical) Band which does not require any
permission to use.
-2.400 –2.4835 GHz, 79 channels
-2.465 –2.4835 GHz, 23 channels (in France)
Transmission Rate : 1Mbps ~ 3Mbps
Transmission Output : 1mW (10m, Class2), 100mW (100m Class1)
Network Configuration : Configured with Master and Slave relation. A Bluetooth unit shall allow
simultaneous connections up to 7 devices (in case of ACL).
Reliability : To Guarantee stable wireless communication even under severe noisy environment
through adopting the technique of FHSS (Frequency Hopping Spread Spectrum).
1.2 Operation of Bluetooth
<Feature 1-1 Bluetooth Operation>
Bluetooth operates based on the connection between “Master”and “Slave”.
Masters are simply supposed to do “Inquiry”and “Page”. Slaves are supposed to do “Inquiry Scan”
and “Page Scan”.
If a Master finds a Slave and so “inquiry”is successful, a Slave responds to the Master with its
information.
Interconnection between the Master and the Slave is achieved only if the information from the
Slave is corresponded with the Master, and the Slave sends data to the Master.

To change the configuration set value of FB155BC, connect FB155BC to the PC using the PC Interface board
then, you may change using the PC software (such as Window Hyper Terminal, FIRMTECH’s PC configuration
program). With MICOM, you may change the set value by using AT command.
Note :
For details on the setting change, please refer to 10 How to complete PC Configuration.

Page 16 / 2
10 Connecting the wireless section of Bluetooth
In order for Bluetooth devices to transmit data to each other, the wireless section of Bluetooth should be
connected to each other. To connect the wireless section, you should set each role for each device, one for a
MASTER, another for a SLAVE. It takes about 1~10 sec that a Master is connected to a Slave.
The connection can be done in use of AT command or connection can be set in use of connection WIZARD
because the initial connection mode of FB155BC is MODE4 (AT Command).
The following contents will be processed under the assumption that the FB755AC & FB755AS are connected
to the interface Board (Jig Board).
※We will use 2 FB155BC and MS Windows in describing procedures.
10.1 Connecting with Connection WIZARD
※The connection WIZARD can not be used if the DEBUG Char is set to 0x00. Please refer to the details
of environment setting in Appendix A for further details.
(1) Connect the interface board of the first FB155BC to the serial port of PC and switch ON.
(2) Execute C-Wizard Program.
<Figure 10-1 Connection Wizard Step 1>
(3) Click FIRMTECH SLAVE Set-up button (<Figure 10-1> Blue borders)

Connection Set-up is completed. With Clicking the End button(<Figure 10-6> Blue borders), finish
the C-Wizard
10.2 Connection with AT commands
The serial communication program is necessary to connect with AT commands.
The setting is available using the hyper terminal offered by Windows and refer to the following “11.2.1
Execution of hyper terminal” to set hyper terminal.
Refer to the “4. How to use AT commands” of “Appendix B –AT Command Language with Detailed
Description and Usage” to use the AT command.

11 How to complete PC Configuration?
The following PC Configuration shall be explained on the assumption that FB155BC is connected with PC
Interface Board(Jig board). If it is connected to MICOM, then you can change the set value by using AT
command language with reference to Attachment AT command language.
Components for PC Configuration
- FB155BC module
- PC Interface Kit
The PC Configuration could be processed with two significant ways.
First one is to use Config tool provided by FIRMTECH Co., Ltd.
Second one is to use serial communication program (Hyper Terminal, minicom) providing OS.
The respective way of setting is as follows.
11.1 PC Configuration using BTConfig tool
(1) Connect FB155BC to PC Interface Board, then connect to COM port(Serial port) of PC.
(2) Switch on the PC interface board in pressing the FASET button (The 4th switch in <Fig. 6-1>)
<Figure 11-1 BTConfig tool initialization>
(3) Execute BTConfig tool after connect FB155BC to serial port of PC.
(4) Click “SERIAL OPEN”button. (<Figure 11-1> blue borders)
