(note 1) Sout / RTS Flow control output from LinkMatik SE. When high, do not send data to LinkMatik SE. Connected to the BASIC Stamp Sout pin in WFP mode. Status Output indicating connect state. Vcc 5V power supply peak requirement 250mA Default: High at startup starts WFP mode; low at startup starts slave mode. Option 1: High at startup starts master mode; low at startup starts slave mode. WFP / Master / Slave Option 2: High at startup starts WFP mode; low at startup starts master mode. Option 3: Operates in WFP mode whatever the state of this pin. Option 4: Operates in Slave mode whatever the state of this pin. Option 5: Operates in Master mode whatever the state of this pin. 1. Output uses 4k7 pull-up resistor and a pull-down transistor. 2. Also powers some circuits, drawing 10mA. 3. Must be pulled low to enter sleep state. Leaving this pin floating is not sufficient. Operating Modes There are three modes of operation. WFP mode is used for programming BASIC Stamps. In slave mode, the LinkMatik SE operates as a Bluetooth transceiver that allows other devices to connect to it. In master mode, the LinkMatik SE operates as a Bluetooth transceiver and actively looks for other devices to connect to. When the Connect / Sleep pin goes high, LinkMatik SE inspects the state of the WFP / Master / Slave pin and decides which mode to operate in. By default, if it is low, it enters Slave mode. If it is high, it enters WFP mode. The module can also be configured so that it can enter Master mode depending on the state of the WFP / Master Slave pin at startup. Refer to the Device Configuration section to activate Master mode. Wireless Field Programming (WFP) Mode LinkMatik Stamp Edition contains a special mode called WFP mode for programming BASIC Stamps BS2, BS2sx, BS2p, BS2e and BS2pe. To use it you should be familiar with the BASIC Stamp Editor from Parallax Inc. You must also download the Stamp WFP Development Kit from This contains the Stamp WFP application which is used to program Stamps, and the sample BASIC file WirelessProg.bsp which is used in the tutorial below. You will require a PC running Windows ME (with service pack 2), Windows 2000 or Windows XP. It will also need an inbuilt Bluetooth radio or a USB Bluetooth adapter, and you will need to know how to make serial connections from that radio to other Bluetooth devices. The module is placed in WFP mode according to the state of the WFP / Master / Slave pin at power-up. In its default setting, WFP mode will start if the WFP / Master / Slave pin is high at power-up. Other settings are possible see the Device Configuration section. If placed in WFP mode, the module cannot be used for regular Bluetooth communication without resetting the module by removing and re-applying power. To use the module in WFP mode, connect a BASIC Stamp as shown in the diagram on the next page. The diagram assumes the WFP / Master / Slave pin is in its default configuration and that connecting it to Vdd will place it in WFP mode. In the photograph, a BS2p Stamp and the LinkMatik SE are shown correctly connected using the BS2p Demo Board and the programming cable accessory. The LED shown has an integral 1k resistor.

3 Vdd Vcc BASIC Stamp ATN Sin Sout Connect Vcc / sleep WFP/M/S ATN LinkMatik SE Sin Status Sout 1k Vss Provided you are not using the ATN, Sin and Sout pins in your BASIC Stamp application, you do not need to disconnect the Stamp from the rest of its circuit to program it. However, if you were using the LinkMatik as a Bluetooth transceiver in the circuit, you would need to disconnect that from its circuit first. The LED is optional. Once you have connected the LinkMatik SE to the Stamp, follow these steps to program the Stamp: 1. Locate the file WirelessProg.bsp in the LinkMatik SE Development Kit and open it using the BASIC Stamp Editor. You will see that all the program does is write data to the debug terminal. 2. If the BASIC Stamp you are using is not a BS2p, change the directive {$STAMP BS2p} so that it refers to the correct type of stamp, and save it with the correct file extension. 3. Next you will use a program called Stamp WFP.exe to program the Stamp. Before you do so, you must check the syntax and save the BASIC file. Type Ctrl+T to test check the syntax and then Ctrl+S to save the file. Try to get into the habit of typing Ctrl+T, Ctrl+S before switching to Stamp WFP.exe, because if you forget to save the file, Stamp WFP will open the version that was last saved. 4. Apply power to the LinkMatik SE and the Stamp. If an LED was attached to the Status pin, it will flash rapidly indicating that it is waiting for your PC to connect. From the Bluetooth Manager application on your PC, search for the device whose name begins LinkMatik SE and connect to it. If the Bluetooth Manager asks you for a PIN code, you can choose to use no PIN code or use the PIN code The Bluetooth Manager will confirm that the connection has been made. 5. Locate and start Stamp WFP.exe in the LinkMatik SE Development Kit and start it. Note that the file Tokenizer.dll, also in the development kit, must be in the same directory. The first time you run it, the screen will look like the screenshot on the right. Find out which COM port was used by the Bluetooth Manager to connect to the ToothPIC. It probably told you during step 4. Sometimes, this COM port is called the Bluetooth outgoing COM port or the Client Applications COM port. Enter the COM port number in the box provided and then press the Program tab. Once you have established the Bluetooth connection, the LinkMatik will stay connected and you can program the Stamp (or multiple Stamps) as often as you like.

4 6. Press the Browse button on the Program tab. Locate the WirelessProg file you saved in step 3 and select it. 7. Ensure the programming settings are set as shown on the right. You may need to select that you are using a LinkMatik Stamp Edition. Note the options for what to do after programming. You can enter debug mode immediately or simply wait. Select to enter debug mode after programming. (Ignore the normal ToothPIC mode option.) 8. Press the Program Now button to program the Stamp. Note that if the $STAMP directive specified multiple programming slots, all slots will be programmed. When programming is complete, Stamp WFP will automatically switch to the Debug tab and debug data will appear. Note how the debug screen shows Debug line 1 being repeated line after line. It was intended to count upwards each line, but the code to increment the counter was omitted. Go back to the Stamp Editor and add the line i = i + 1 after the line with the DEBUG command. Press Ctrl+T, Ctrl+S to verify and save your changes. 9. Back in Stamp WFP, switch to the Program tab and press the Program Now button again. The Stamp will be reprogrammed and the correct debug messages will be shown as pictured right. You have now seen how to program BASIC Stamps wirelessly using the LinkMatik SE and the Stamp WFP application. If that s all you need to do for the moment, then you do not need to read about Slave and Master mode. Later, when you want to use the LinkMatik SE for communicating via Bluetooth, you can start again from the next section. Slave and Master Modes In Slave mode, LinkMatik SE is placed in a detectable state. Unless it has been configured as Monogamous and it has already found a partner, it will allow any device to connect to it. A PIN code may be required, depending on configuration. If the remote device disconnects, LinkMatik SE returns to the discoverable and detectable state. To disconnect locally, set the Connect / Sleep pin low. In Master mode, LinkMatik SE searches for a partner to connect to. What it connects to is defined by the device configuration. The partner does not have to be another LinkMatik SE. When it finds a partner, it connects immediately. If configured as Monogamous, it will thereafter only reconnect to that specific Bluetooth device. (It will also reconnect much more quickly.) If the remote device disconnects, LinkMatik SE starts searching for a partner again. To disconnect locally, set the Connect / Sleep pin low.

5 In both slave and master modes, the serial data is standard, active-low format with 8 data bits, no parity bit and 1 stop bit. Hardware flow control is supported. If no flow control is required, RTS must be connected to CTS. For RS232 levels, use a level shifter IC such as a MAX232. If authentication is enabled locally or required by the remote device, LinkMatik SE will pair with newly encountered remote devices by exchanging PIN codes. LinkMatik SE will remember up to 7 paired devices. (The eighth device erases the first, etc.) If encryption is enabled or required by the remote device, the link will be encrypted. The PIN code is set in the device configuration. The default is four zeroes. The WFP / Master / Slave pin state should normally remain unchanged. While LinkMatik SE is looking for a partner, a change of state will erase monogamous partner information and any information about paired devices. The change of state should be at least 10ms long. After erasure LinkMatik SE will wait for the WFP / Master / Slave pin state to change state and then resets. Radio Link / Antenna The radio is a 2.4GHz Class I Bluetooth device with an integral antenna. To achieve 100m range, the corresponding Bluetooth device must also be Class I. LinkMatik SE is supplied with an integral antenna. This will provide adequate range for most applications. There is also the facility to attach an external antenna, via the on-board Hirose U.FL series connector. Please note that the product is certified for use with the antenna supplied. Should an alternative antenna be used then EMC re-certification must be sought. The module supports Hold and Sniff power saving modes if requested by the remote device, but cannot enter these states itself. Park mode is not supported. The module is configured with a specific name and device class. The name appears in user interfaces when remote devices search for Bluetooth devices in range. LinkMatik SE also uses the beginning portion of remote device s name in order to decide whether it should connect to them. The device class specifies the type of device. This is used for icons and by remote devices searching for specific device types. To change these settings refer to the Device Configuration section. PCB Mounting Considerations In order to realize the maximum possible range between two modules the antenna position is of importance. During design, consider the RF characteristics of the environment surrounding the module. Experiment with the location and orientation of the antenna and avoid locating it near large conducting materials (e.g. metal, water). Ideally, mount the module so that antenna overhangs the edge of the motherboard. If this is not possible then ensure that there are no other components or metal within 4cm of the antenna. Finally, ensure the area where the module is mounted has a solid ground plane. Device Configuration Settings LinkMatik SE has settings which may be reconfigured using the LinkMatik SE Configuration Tool software. This can be freely downloaded from and/or In large volumes, LinkMatik SE can be supplied with specific configuration settings. The available settings are as follows: The status pin function may be: - Low unless connected - High until initialized, low if unconnected, high if connected - Low until initialized, 1Hz if unconnected, high if connected (factory setting) Page 5 26-Sep-05 LinkMatik SE FlexiPanel Ltd Patents apply and/or pending

6 The baud rate may be: 9600 baud (factory setting) baud baud baud baud The device type defines how the module will appear to be to other Bluetooth devices and will therefore affect the icon that appears on other Bluetooth devices. Note that this may affect the device discovery function, for example some mobile phones only look for certain sub classes, e.g. headsets. Select one of: Imaging device General peripheral Joystick Gamepad Remote control Sensing device Digitizer Card reader Desktop computer Server Laptop computer Handheld computer Palm-sized computer Wearable computer Computer (other) Cellphone (factory setting) Cordless phone Smartphone Gateway / modem ISDN Phone (other) Wearable headeset Hands free audio device Microphone Loudspeaker Headphones Walkman / ipod Car audio Set-top box Hi-Fi VCR / DVD Video camera Camcorder Monitor TV / Monitor with audio Conferencing device Toy LAN 0% utilized LAN 1% - 17% utilized LAN 17% - 33% utilized LAN 33% - 50% utilized LAN 50% - 67% utilized LAN 67% - 83% utilized LAN 83% - 99% utilized LAN 100% utilized Miscellaneous device Uncategorized device The services define the capabilities device. Select as many as appropriate from the following list. Note that services marked or are only selectable for device types having a corresponding or symbol. For an explanation of limited discoverable service, refer to Limited discoverable (factory setting) Information Positioning Keyboard Networking (factory setting) Pointing device Rendering Display Capturing Camera Object transfer (factory setting) Scanner Audio Printer Telephony (factory setting) The device name is an ASCII string of up to 31 characters. This is used during device discovery to identify devices. Each LinkMatik SE module has a unique 12-character hexadecimal Bluetooth ID. To incorporate the Bluetooth ID in the device name, include the ~ in the device name 12 times. LinkMatik SE will substitute the Bluetooth ID characters for the ~ characters. For example, if a LinkMatik SE module with Bluetooth ID ABCDEF uses the factory-setting: LinkMatik SE ~~:~~:~~:~~:~~:~~ Page 6 26-Sep-05 LinkMatik SE FlexiPanel Ltd Patents apply and/or pending

7 The actual device name becomes: LinkMatik SE 12:34:56:AB:CD:EF Note that most Bluetooth device managers store discovered device names locally. If you re-configure the device name, products which have previously discovered the device may continue to display the old name for a while afterwards. If operating in master mode, LinkMatik SE connects to the first device it discovers whose name matches the pair match prefix. If the discovered device name is longer than the pair match prefix, characters beyond the end of the pair match prefix are ignored. For example, the factory setting is: LinkMatik Which specifies that the module will attempt to connect to any device whose name begins with LinkMatik. If operating in slave mode, the pair match prefix is ignored; LinkMatik SE accepts connection from any device, subject to authentication settings. The mating mode specifies whether LinkMatik SE stays paired once first connected. The factory setting is polygamous mode, where LinkMatik SE will allow connection with any device that fulfils the pair match criteria. In monogamous mode, once LinkMatik SE has successfully connected to any device, it will thereafter only connect to that device. To erase monogamous partner information, change the state of the WFP / Master / Slave pin as specified in the Bluetooth Operation section. The PIN code is an ASCII string of up to 16 characters. This is the code used during bonding if authentication is enabled either on LinkMatik SE or on the remote device. Note that some devices can only enter the digits 0-9 in PIN codes. The factory setting is four zeroes, which is the de facto Bluetooth default value. The Security setting defines the level of security with which connections are made. If authentication is selected, LinkMatik SE will only allow connection to a device whose PIN code matches its own. If encryption is enables, the link is encrypted. The factory setting is authentication and encryption. The WFP / Master / Slave defines how the state of this pin is interpreted at startup and consequently in which modes LinkMatik SE operates. Select one of: High at startup starts master mode; low at startup starts slave mode. High at startup starts WFP mode; low at startup starts slave mode. (Factory setting) High at startup starts WFP mode; low at startup starts master mode. Operates in WFP mode whatever the state of this pin. Operates in Slave mode whatever the state of this pin. Operates in Master mode whatever the state of this pin Device Configuration Process To configure a LinkMatik SE module, you will require a PC running Windows ME (with service pack 2), Windows 2000 or Windows XP. It will also need an inbuilt Bluetooth radio or a USB Bluetooth adapter, and you will need to know how to make serial connections from that radio to other Bluetooth devices. The following steps allow you to configure a LinkMatik SE module: 1. Connect the module as shown in the schematic diagram below. You will require a 4k7 resistor with a tolerance of 1% and an LED with a 1K current limiting resistor. 2. Apply power. If configured correctly, the LED will flash rapidly (10Hz) after initialization, indicating that LinkMatik SE is in configuration mode. Note that this is actually the same operating mode as WFP mode only the software you use on the PC is different. If the current settings allow you to enter this mode another way, you can omit step 1.

8 3. Download and run the LinkMatik Configuration Tool application on a Windows PC. This file is in the LinkMatik SE Development Kit. 4. The factory settings are shown in the screen capture below. Change these settings to the settings you require. If you run the application again later, it will remember the settings you previously selected. 5. Ensure that no applications are connected to the PC s Bluetooth COM port. These might include Windows HyperTerminal, if you have been evaluating LinkMatik SE, and some ActiveSync programs which try to stay permanently connected. 6. Using the Bluetooth device manager on the PC, discover and connect to the LinkMatik SE module. Authentication is disabled in configuration mode, so LinkMatik SE will not require a PIN code. However, if your PC requires the use of a PIN code, you must use the code currently programmed into the LinkMatik SE module. 7. Make a note of the COM port that the Bluetooth device manager uses to connect to LinkMatik SE and enter the COM port value in the box marked Connected to COM port. 8. Press the Program LinkMatik SE Now button. Successful configuration will take about a second. When complete, the LED will stay lit constantly. If configuration fails for any reason, an error message will be displayed and you should restart from step Power down, remove the 4k7 resistor and then re-apply power. LinkMatik SE will now operate in the new configuration. The first time it initializes, it may take a little longer than usual. Please note that many Bluetooth devices store information about other devices locally, so changes made may not be apparent. In particular, once the name has been changed, the new name may not immediately appear on a device which has previously discovered the device under its old name. The best way to check that reconfiguration has been successful is to scan using a device which has never encountered the LinkMatik SE before.
