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

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

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.

8 How to Complete PC Configuration

The following PC Configuration shall be explained on the assumption that FB755AC & FB755AS 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

- FB755AC & FB755AS 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 FB755AC & FB755AS 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 th e power ON. (3) Execute Config tool.

FB755AC & FB755AS Version 1.0.3

(4) Select “CONNECT”(<Figure 8-1> Blue Lined) on the main display.

1 Select Product : Name of Product in Use 2 DEBUG CHAR : Default is 0x02. (Appendix : Refer to details of PC Configuration) 3 Set Serial Port : Default is BAUD RATE : 9600, PARITY BIT : None, STOP BIT : 1

(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 reexecute the config tool.

FB755AC & FB755AS Version 1.0.3

2 Status Value : Output the status value with the form of message. 3 Status 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.

1 READ STATUS Button : To read in the PC configuration set in the product. 2 WRITE STATUS Button : To store the value set in the PC configuration window into the product 3 Factory Setup Button : To reset all the PC configuration value to the factory set value.

(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.

8-2 PC Configuration using Serial Communication(Hyper Terminal) Program

8-2-1 To execute Hyper Terminal To set up PC configuration using Hyper Terminal, following works will have to be done before power is authorized to the PC connected with the product. To accomplish the PC configuration, serial communication program is required. Here Hyper Terminal will be used for explanation.

(1) Set the Config Select on the PC Interface Board (Jig Board) ON. (2) Execute in the order of [start]Æ[All Programs]Æ[Accessories]Æ[Communications]Æ [Hyper Terminal], then connection window will appear on which enter appropriate name and click.

(3) When the <Figure 8-6> comes up, select the COM port connected to FB755AC & FB755AS, and clicks the Acknowledge button.

- 22 -

FB755AC & FB755AS Version 1.0.3

(4) When Registration Information Window comes up as on <Figure 8-7>, select Bit per second : 9600, Data bit : 8, Parity : none, Stop bit : 1, Flow control : none, which will execute Hyper Terminal.

- 23 -

FB755AC & FB755AS Version 1.0.3

(5) Basically, the Hyper Terminal does not show the entered character. To make sure of the entered character, select [File]Æ[Properties] on the Menu, then registration information window will appear shown as on <Figure 8-8>, click the ASCII Setup button.

(6) As shown on <Figure 8-9>, “Check Echo typed characters locally” and come out pressing the acknowledge button. Now the Hyper Terminal program setting procedure is completed to use PC Configuration.

- 24 -

FB755AC & FB755AS Version 1.0.3

(7) If power is authorized on the Interface Board, the menu as shown on <Figure 8-10> will be output on the Hyper Terminal.

8-2-2 How to Use PC Configuration Menu

The user will select the menu want to change. To select the menu, you may just select the number given on the left side. For example : To change “DEVICE NAME”, enter : [“0”]Æ[Enter]

Note : At <Figure 8-10> condition, Pressing Reset button for more than 2 seconds will reset all the configured values to the initial status (factory preset status).

Following is the order to use the menu. (1) The execution will only be executed by pressing the “Enter” key. (2) The small character “t” will always move to be positioned at upper side of the menu. (3) To move menu, use the number in the end of left side. Please be sure to “Enter” key upon completion of input. (4) “←” key is used to delete the entered character currently. (5) If the entered character is unreadable or is not supported at the appropriate menu, “Retry >” message will be output. (6) If the input message is more than 12 characters, “Overflow buffer” message will be output and then “Retry >” message appeared as well.

Upon completion of all PC configuration, turn off the Interface Board, switch the Config Select switch OFF, and turn the power ON, which will start the Bluetooth to operate normally.

Note : Please refer to Appendix A PC Configuration for the detailed description on the

configuration value.
