Manufactured to ISO9001:2000 Description Bluetooth Evaluation Board Bluetooth Evaluation Board DS378-2 © FlexiPanel Ltd Patents apply and/or pending www.FlexiPanel.com Evaluation Board Overview I2C memory Intended uses The 24C256 I2C serial memory is conditionally connected, according to the configuration pins, to pins SDA and SCL of the Toothpick. The primary aim of the Bluetooth Evaluation Board is to allow evaluation of FlexiPanel Ltd’s Bluetooth products as easily as possible. It is designed to allow the developer to follow the tutorials and examples in the product data sheets. Additionally, the evaluation board can be used during development as a reliable, tested environment while troubleshooting. Power Supply The evaluation board may be powered by a reasonable smooth unregulated 5V – 12V DC power source via the 2.5mm center-positive connector. No heat sink is provided for the voltage regulator, so expect it to get quite warm. Switches, LEDs and Presets The following peripheral permanently connected: components are • LEDs to Toothpick pins AN9, AN10, AN11, CCP1 and SDO. • Presets that can vary the voltage of Toothpick pins AN0, AN1, AN2 and AN3 smoothly between 0V and 5V. • Pushbuttons to control the voltages of Toothpick pins AN4, AN5, AN6 and AN7. 5V when pressed and 0V otherwise. • Bit 2 of the binary encoding rotary switch to CCP5. • Bit 3 of the binary encoding rotary switch is unconnected. • Power LED. • LED connected to the Status pin of the LinkMatik and the MUM pin of the BlueMatik. The following peripheral components are conditionally connected according to the configuration pins as detailed in the General Setup sections: • LEDs to Toothpick pins CCP2, CCP3, SDA, SCL, TxD • Bit 1 of a binary encoding rotary switch to CCP4. • Bit 0 of a binary encoding rotary switch to RxD. Page 2 30-Mar-06 Bluetooth Evaluation Board DS378-2 Pull-up resistors are included. The address pins are all held low, so the Toothpick mStr value to access the memory is 0x10. ICD2 programming connector The RJ11 programming connector allows you to program a ToothPIC directly using Microchip MPLAB ICD2. Since the NMCLR, INT0 and INT1 lines must be isolated, no BASIC Stamp should be installed at the same time as an IDC2 is connected. Jumper connections Jumper connections allow the evaluation board to be dynamically reconfigured as detailed in the General Setup sections. A key is printed next to each jumper connection strip. The pin columns are denoted by letters, the rows by numbers. Note that the links might need to be inserted in either the horizontal or vertical positions. Switches SW7 switches the LinkMatik Connect / Sleep pin between the Sleep state and the On state. SW6 may be used to switch the LinkMatik Master / Slave Mode pin between Master and Slave modes, and to switch the BlueMatik HUM pin between Command and Data modes. Note that whether this switch has any effect depends on the jumper settings, since these modes can alternately be driven by the state of the RS232 DTR line. RS232 driver and Serial Port The serial port may be used by any of Toothpick, LinkMatik, BlueMatik or the BASIC Stamp according to configuration. Module Sockets Only insert one of BlueMatik, LinkMatik and Toothpick at a time. Only insert a BASIC Stamp when used with Toothpick Stamp Edition. © FlexiPanel Ltd Patents apply and/or pending www.FlexiPanel.com Toothpick General Setup Toothpick Slave Tutorial Insert the Toothpick in the evaluation board so that the antenna overhangs the edge of the board.

There should be nothing inserted in the Toothpick, Stamp and BlueMatik sockets. Remove any existing links and then insert links over the following configuration pins: To evaluate LinkMatik in slave mode, put the SW7 switch in the Sleep position, remove any existing links and then connect the links as follows: A3 – A8 – A10– B2 – B5 – B8 – A4 A9 B10 B3 B6 B9 A3 – A8 – A10– B2 – B5 – B8 – E7 – E4 – E9 – (RS232 TxD to RxD pin) (RS232 CTS to RTS pin)* (RS232 CTS to RTS pin)* (RS232 RTS to CTS pin) (RS232 RxD to TxD pin) (RS232 RTS to CTS pin) A4 A9 B10 B3 B6 B9 E8 E5 F9 (RS232 TxD to RxD pin) (RS232 CTS to RTS pin) (RS232 CTS to RTS pin) (RS232 RTS to CTS pin) (RS232 RxD to TxD pin) (RS232 RTS to CTS pin) (SW6 to MSM input) (RS232 TxD to RxD pin) (RS232 RxD to TxD pin) *Note: on one version of the board (TPDr5 ), the “A8 – A9” and “B8 – B9” is omitted on the rearside labels. LinkMatik is now configured so that the MSM input is controlled by SW6 and the Connect / Sleep line is controlled by SW7. You can decide whether the MSM input is controlled by switch SW6 or via the DTR line on the RS232 port. To control it from the switch SW6, insert a link over the following configuration pin: Apply power and put SW6 into the Slv position. Then put SW7 into the On position. The Status LED should flash to indicate that it has entered Slave mode and is waiting for a device to connect to it. E7 – E8 (SW6 to MSM input) To control the HUM input from DTR line, insert links over the following configuration pins: A6 – A7 E7 – F7 (DTR to MSM input) (DTR to MSM input) To operate in normal transceiver mode, insert links over the following configuration pins: E4 – E5 E9 – F9 (RS232 RxD to TxD pin) (RS232 TxD to RxD pin) To operate in configuration mode, insert links over the following configuration pins: E4 – F4 F8 – F9 (4k7 pull-down to TxD pin) (4k7 pull-down to RxD pin) To see the LinkMatik working, two HyperTerminal sessions much be started on a PC. One will be connected via the RS232 port, the other via Bluetooth. What you type into one console will appear in the other. First connect the DB9 socket to your PC’s serial port. Start a HyperTerminal session at 9600 baud, hardware flow control, 8 bits no parity, one stop bit. Second, use the Bluetooth Manager on your PC to discover LinkMatik. You will need to pair with it, since security is enabled. The PIN code is four zeroes ‘0000’. Connect to LinkMatik and observe that the Status LED glows steadily as the connection is complete. Start another HyperTerminal session, using the COM port number assigned by the Bluetooth Manager when you made the connection. The baud settings are ignored, so enter anything you like for them. You should now find that anything you type in one HyperTerminal window appears in the other HyperTerminal window. Page 5 30-Mar-06 Bluetooth Evaluation Board DS378-2 © FlexiPanel Ltd Patents apply and/or pending www.FlexiPanel.com Configuration Mode Master Mode Important: If you have previously run the Slave Mode evaluation, be sure to close the HyperTerminal windows as they will otherwise ‘hog’ the COM ports and prevent correct Bluetooth communication. To evaluate LinkMatik in master mode, first complete the configuration mode evaluation since this configure LinkMatik to connect to your PC. The with the SW7 switch in the Sleep position, remove any existing links and then connect the links as for the slave mode evaluation: To evaluate LinkMatik in configuration mode, put the SW7 switch in the Sleep position, remove any existing links and then connect the links as follows: A3 – A8 – A10– B2 – B5 – B8 – E7 – E4 – F8 – A4 A9 B10 B3 B6 B9 E8 F4 F9 (RS232 TxD to RxD pin) (RS232 CTS to RTS pin) (RS232 CTS to RTS pin) (RS232 RTS to CTS pin) (RS232 RxD to TxD pin) (RS232 RTS to CTS pin) (SW6 to HUM input) (4k7 pull-down to TxD pin) (4k7 pull-down to RxD pin) A3 – A8 – A10– B2 – B8 – B5 – E7 – E4 – E9 – A4 A9 B10 B3 B9 B6 E8 E5 F9 (RS232 TxD to RxD pin) (RS232 CTS to RTS pin) (RS232 CTS to RTS pin) (RS232 RTS to CTS pin) (RS232 RTS to CTS pin) (RS232 RxD to TxD pin) (SW6 to MSM input) (RS232 TxD to RxD pin) (RS232 RxD to TxD pin) LinkMatik is now configured so that the MSM input is controlled by SW6 and the Connect / Sleep line is controlled by SW7. Apply power and put SW7 into the On position. The Status LED should flash rapidly, indicating that it is in configuration mode. Use the Bluetooth Manager on your PC to discover LinkMatik and connect to it. If your computer requires it, use the PIN code of four zeroes 0000. Also in the Bluetooth Manager, make a note of your PC’s Bluetooth device name. Start the LinkMatik configuration tool and enter the first few characters of the PC’s Bluetooth device name as the Pair Match Prefix. For example, the PC used to write this documentation has the name FlexiPanel Vaio Laptop, so FlexiPanel was entered as the Pair Match Prefix. This is being done so that in the next section, where master mode is evaluated, LinkMatik will search for and connect to the PC. Apply power and put SW6 into the Mstr position. Then put SW7 into the On position. The Status LED should flash to indicate that it has entered Master mode and is looking to connect to your PC. After a few seconds it should discover your PC and it will automatically connect to it. Depending on whether previous pairings have been remembered or not, it may be necessary to enter the PIN code 0000 on the PC again. If you wish to verify that the connection is working, start two HyperTerminal sessions on the PC as you did for the Slave Mode evaluation. What you type into one console will appear in the other. Press the Program LinkMatik Now button to write the new settings to LinkMatik. The LED will extinguish for one second and then glow steadily indicating configuration is complete. The first time you power up after programming, Page 6 30-Mar-06 Bluetooth Evaluation Board DS378-2 © FlexiPanel Ltd Patents apply and/or pending www.FlexiPanel.com BlueMatik Example AT commands General Setup The following examples are not exhaustive.
