What is Bluetooth?
1. Features of Bluetooth
1) Objectives of Bluetooth : To Realize Wireless Communication for Short Distance with Low
Power Consumption, High Reliability, and Low Cost.
2) 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)
3) Transmission Rate : 1Mbps ~ 3Mbps
4) Transmission Output : 1mW(10m, Class2), 100mW(100m Class1)
5) Network Configuration : Configured with Master and Slave relation. A Bluetooth unit shall
allow simultaneous connections up to 7 devices (in case of ACL).
6) Reliability : To Guarantee stable wireless communication even under severe noisy
environment through adopting the technique of FHSS (Frequency Hopping Spread Spectrum).
2. Operation of Bluetooth
<Figure 0-1 Operation of Bluetooth>
1) Once the Master will inquire the Slave, the Slave will respond to the inquiry to the Master.
2) When the information of Slave will agree with that of the Master, the interconnection will be
achieved to transmit the data.

seconds then all the set value shall be changed to the initial factory set value.
- STATUS port
To be used to monitor the status of FB155BC.
To keep LOW(0V) when the two devices are communicable since the connection between
wireless range is smoothly made.
In standby mode for connection with Bluetooth, or connection trial, or searching for around
Bluetooth device will repeat LOW and HIGH.

8 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.
8-1 PC Configuration using Congfig tool
(1) Connect FB155BC to PC Interface Board, then connect to COM port(Serial port) of PC.
(2) Set Config Select Switch of PC Interface Board OFF and then turn the power ON.
(3) Execute Config tool.

(4) Select “CONNECT”(<Figure 8-1> Blue Lined) on the main display.
1Select Product : Name of Product in Use
2DEBUG CHAR : Default is 0x02. (Appendix : Refer to details of PC Configuration)
3Set Serial Port : Default is BAUD RATE : 9600, PARITY BIT : None, STOP BIT : 1
<Figure 8-2 : config tool CONNECT Display>
(5) When the <Figure 8-2> appears, select each selective item of red lines box 1~3, then
press connect (red box line 4) which will change Serial connection, Ready To Set (red lined box
1) into Green as shown on <Figure 8-3>.(The selected value will be certified at the
preliminary setting of product.)
If the color does not change into green, please make sure of the Baud rate of product and re-
execute the config tool.

2Status Message : Display the status of command language in progress
<Figure 8-3 : config tool connection display>
(6) After the product and config tool is connected properly, select CONFIG button(blue lined
box) on Figure<8-3>, display like <Figure 8-4> will comes up to allow to configure the
environment.

2Status Value : Output the status value with the form of message.
3Status of Command Language : Since the preliminary operation method is to use AT command, the
progressed AT command language will output in the form of message.
1READ STATUS Button : To read in the PC configuration set in the product.
2WRITE STATUS Button : To store the value set in the PC configuration window into the product
3Factory Setup Button : To reset all the PC configuration value to the factory set value.
<Figure 8-4 : config tool Device Configuration >
(7) To summarize the setting up the config tool, follow the procedures as under.
- To strore the set value upon completion, please be sure to click WRITE STATUS button.
- Click READ STATUS to read in the stored configuration value to certify the they are correct or
not.
- If you want to set as the status first received, click Factory Setup to reset the first received
value.
- Since the config tool was made based on AT command of the product, it is possible to
represent the ongoing command language and its status at the form of status value and
message window.
Note : Please refer to Appendix PC Configuration for detailed explanation.
