4 1. INTRODUCTION AND OVERVIEW is Bluetooth wireless module from Cytron Technologies which is design to adapt the from factor of XBee module. The pinout of is compatible with XBEE which is suitable for all kinds of microcontroller systems that have 3.3V power out. There are 2 modes on which is Transparent mode and AT mode. The baudrate of module may be set using AT commands/mode. The 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. is compatible with XBEE starter kit, so you may use SKXBEE-BOARD or Arduino-XBee shield for communication. The is only slave module. Communication among two is not possible. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 4

11 ROBOT. HEAD to TOE 6. HARDWARE INTERFACE SKXBEE-Board or UC00A/B may use to enabling bluetooth wireless control. This section will show 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 is compatible with XBEE, user may use this board for Bluetooth wireless communication. Plug 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 USB Serial port is COM50. Now you can start communicating with module, in AT mode or Trans mode.

12 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 module onto XBEE Breakout board. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 12

13 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 should be connected to Rx pin of UC00A/B and Rx pin of should be connected to Tx pin of UC00A/B. Ensure 3.3V is select on UC00B. *Please ensure to select the corrent voltage, else will be damaged, same apply if UC00A is used. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 13

14 ROBOT. HEAD to TOE 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 SKXBEEBOARD COM port. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 14

15 7.0 AT COMMAND 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. 1.Test Command Response Parameter AT OK None 2. Reset Command Response Parameter AT+ RESET OK None 3.Get module bluetooth module address Command Response Parameter AT+ADDR? +ADDR:<Param> OK Bluetooth address will show as this way: NAP:UAP:LAP (Hexadecimal) Example: Module Bluetooth address: 12: 34: 56: ab: cd: ef at+addr?\r\n +ADDR: 1234:56:abcdef OK Param: Bluetooth address Created by Cytron Technologies Sdn.

17 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. module need to set to AT mode shown as figure below. Status LED will blink with slow blinking when in AT mode. Open and set up HyperTerminal. Bare in mind that the baud rate for AT mode is bps. Figure below is an example to send AT command using HyperTerminal. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 17

19 8.0 GETTING STARTED is a slave module, so communication among two 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 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 and computer B as a host to Bluetooth USB dongle. is using SKXBEE -BOARD or UC00A/B to communicate with computer A and bluetooth dongle will use BlueSoleil software to communicate with computer B. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 19

21 Setup for computer A: Set 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 is COM50 and baud rate is 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). Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 21

22 Press F5 to start searching for Bluetooth device near by. If is working properly, it will appear as a Bluetooth node in BlueSoleil window as shown in following figure. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 22

23 Right click on con and click pair device. The software will appear a window to Enter Bluetooth Passkey. Enter the passkey and click OK. The passkey should be When the bluetooth serial is paired, status LED blinking is change from fast blinking to slow blinking. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 23

24 Now, double click on the Bluesoleil will start inquiring for available service or profile offered by. 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. Created by Cytron Technologies Sdn.

26 BlueSoleil will try to create Bluetooth Wireless link with and offer serial port service. Status LED on will blinking 2 times in 1 second (2Hz) if the Bluetooth Wireless link is successfully created. Open and setup HyperTerminal for computer B. For this example port setting for Bluetooth is COM49 and the baudrate is Type any words at HyperTerminal computer A. User may see, the words types on HyperTerminal computer A will be received by HyperTerminal computer B and displayed. Then, type any words at HyperTerminal computer B and those words also received and displayed on HyperTerminal computer A. That means that Bluetooth link is created and data is able to communicate (transmit and receive) between computer A and computer B. Created by Cytron Technologies Sdn. Bhd. All Rights Reserved 26
