The CSR CASIRA Bluetooth Development kit has been developed primarily to assist CSR’s customers in the development of host-side software and external radio circuits outside the BlueCoreT M ICs. It will also be used to assist CSR’s customers to evaluate the BlueCoreT M chips. The Evaluation system consists of two identical modules that allow the user to send both data and voice over a Bluetooth link. Each unit is driven from a PC for data connections and from a headset (supplied with the kit) for voice connection. Each unit consists of a motherboard and a Bluetooth radio transceiver daughter card module. The first radio module shipped with the system uses the CSR BlueCore01 chip and also includes the front-end filter, an LNA, a PA, a TX/RX switch, a flash memory, a crystal and an external (connectorised and detachable) antenna. The radio module plugs into the motherboard. Hardware upgrades will be shipped in the format of a new replacement radio module when new versions of the CSR BlueCore IC product range become available. The motherboard provides a serial port (RS232), SPI port, USB port, PCM port, power supply socket and audio socket. Headset Socket RS232 Port USB Port Power Socket Power LED One CASIRA Bluetooth Development kit Unit The on-board CODEC can be used for the voice interface although it is possible to connect direct to the PCM connection via the internal Molex connector. The signal BC01-um-001c Page 6 of 26 levels on the RS232 port conform to the RS232 standard and are generated on the motherboard. It is also possible to connect to the BlueCoreT M01 UART using CMOS (3V) levels using the second internal Molex connector on the 3V UART/Serial PCM port. The USB port is type “B”. SPI Interface LEDs 3VUART/ Serial PCM Port PIO Interface Detachable Radio Module Reset Motherboard Inside the CASIRA Development kit Bluetooth USB Functionality. First systems do not support USB. The first new BlueCoreT M radio module upgrade will support USB. This is expected to be available in Q3 2000. Note: When using USB the UART CTS and UART RTS pins are used for the USB- and USB+ respectively. Hence it is not possible to use one unit with both USB and RS232 connections operating simultaneously. Eight LED’s are provided on each module and the function of each is as follows LED 0 Radio RX ON LED 1 Radio TX ON LED 2 ACL/LMP data received LED 3 ACL/LMP data transmitted LED 4 SCO data received LED 5 SCO data transmitted LED 6 UART data received LED 7 UART data transmitted BC01-um-001c Page 7 of 26 3 CASIRA BLUETOOTH DEVELOPMENT KIT The following items are included in the CASIRA Bluetooth Development kit Qty Description Carry-case with handle and external sleeve CASIRA Bluetooth Development Kit Units Power supplies SPI Programming leads 5 Metre long RS232 leads Country specific Mains adapter plugs Audio Headsets CSR CASIRA Bluetooth Development kit CDROM containing documentation and software.

BC01-um-001c Page 8 of 26 4 HARDWARE SETUP Remove the power supplies and the appropriate mains power connectors from the carry case and push the mains connector onto the power supplies, making sure that they are fully pressed home. Plug these two power supplies into the mains but DO NOT connect the DC output connector to the BlueCore Evaluation System units yet. The power supplies should be connected AFTER the BlueChat application is installed and configured. Remove the two serial cables from the carry case and connect one end of each to the COM ports on two PC’s (WindowsT M98 / NT). Connect the other ends of the serial cables to the COM1 port of each of the CASIRA Bluetooth Development kit Units. Remove the two headsets from the carry case and connect one to each of the CASIRA Bluetooth Development kit Unit headset sockets. BC01-um-001c Page 9 of 26 5 OVERVIEW OF THE BLUECHAT APPLICATION. The CSR CASIRA Bluetooth Development kit is supplied with a PC program called BlueChat that allows the user to send text, send a file and set up a voice connection between the two system units. A single window display gives a constant report on the Bluetooth radio link via a watch window. The communication between the PC and the CASIRA Bluetooth Development kit Units is at the HCI level. BC01-um-001c Page 10 of 26 6 INSTALLING THE BLUECHAT APPLICATION The BlueChat Application allows the user to issue commands via the RS232 port of a PC running under Windows™98 or Windows™ NT to the Development system units. The software must be installed from the CSR CASIRA Bluetooth Development kit CDROM provided. System Requirements for the BlueChat Application - Pentium processor-based personal computer - Microsoft Windows™98 or Windows™ NT v4.0(service pack 3 or later) - 16 MB of RAM (24 MB recommended) - 10 MB of available hard disk space Installation instructions: Insert the CASIRA Bluetooth Development kit CDROM into your CDROM drive. From your CDROM in the “software\host\BlueChat”folder run the file “install.exe” and change the path if required, Click “unzip”, Click “OK” and finally Click “CLOSE” to complete the installation. From your “BlueChat” folder create a shortcut for BlueChat.exe and place it on your desktop or taskbar for convenience as required. BlueChat should now be installed and ready for use. BC01-um-001c Page 11 of 26 7 CONFIGURING THE BLUECHAT APPLICATION Start the BlueChat Program on each PC by double Clicking on the BlueChat shortcut on your desktop, or on the BlueChat Icon in the BlueChat folder. A port selection window will appear: Click on the drop down menu button and select the COM port that you connected the serial cable to for that PC. Click “OK” when your selection is complete. Up to two BlueChat windows may be open at any one time allowing a single PC to be used for both evaluation modules. In this mode a different COM port must be selected in each window and each of the CASIRA Bluetooth Development kit Units must be connected to the appropriate COM port. Now plug in the the power supplies to the CASIRA Bluetooth Development kit System Units. The following screen should appear after a few seconds with the associated messages to show that each PC has connected to the system unit: BC01-um-001c Page 12 of 26 8 ESTABLISHING AN ACL CONNECTION First make sure that the Xfer type is still set at the default power-on value of ‘data’. Then select the Role of one unit to be the slave by selecting the slave button: WARNING –See appendix for a known software deficiency after initial power up of System Units Selecting a slave causes the first unit to enter inquiry scan mode: Next, selecting the role of the other system unit to be master will now cause an “Inquiry” to be initiated by the master The master now collects Bluetooth addresses from Slave modules that can been found on the radio channels. The “Host Controller Interface Message” window will give information on the results of the Inquiry. This procedure should take approximately 10 seconds to complete. It is usual to see 8 responses after inquiry scan is complete : The user must ensure that the CASIRA Bluetooth Development kit Units are NOT both set to the same Role BC01-um-001c Page 13 of 26 On completion of the Inquiry, the addresses of any Slaves found will be shown in the “Bluetooth Device Addresses” list. Next select a Slave from the list as shown below. It is only necessary that the the address is shown (selected) in the “Connect to:” window, it is NOT necessary to hit return at this point. Next click on the Connect button at the master If only one slave is discovered then its address automatically appears in the “Connect to:” window and it is then only necessary to click on the “Connect” button. The ACL link to the Slave is now set up and the following results are shown at the master BC01-um-001c Page 14 of 26 9 SENDING TEXT BETWEEN SYSTEM UNITS OVER AN ACL CONNECTION Once the connection between the two modules has been completed text data can be sent by clicking on the Chat link window and typing a message. The text should appear in the Chat link window at the other BlueChat PC. Text transfer is bidirectional between master and slave (but remember to click on the “Chat link “ window first before typing at the other end) 10 SENDING A DATA FILE BETWEEN SYSTEM UNITS OVER AN ACL CONNECTION Data may be sent over ACL connection by clicking on the File Transfer select button, at either the master or the slave BC01-um-001c Page 15 of 26 Select a file to transfer from your chosen directory : Finally press the Send button to transmit the file. A progress bar is shown at during the transmission and when completed the file transfer information is given. BC01-um-001c Page 16 of 26 11 DISCONNECTING AN ACL CONNECTION Pressing the Disconnect button at either system unit will stop the command transfer and close down the ACL connection It is necessary to re-establish the roles of master and slave after a disconnect. However the BlueChat application will remember the Bluetooth device addresses from previously discovered slaves so it is not necessary to repeat an Inquiry before reestablishing an ACL connection. 12 INITIATING AND BREAKING AN AUDIO CONNECTION At startup the default Xfer type is Data. The audio connection can be established by selecting the Audio button after an ACL connection has first been esatblished Audio communication between the two headsets is now enabled. To disconnect an audio connection press the Disconnect button. It is necessary to re-establish the roles of master and slave after a disconnect. However the BlueChat application will remember the Bluetooth device addresses from previously discovered slaves so it is not necessary to repeat an Inquiry before reestablishing an ACL connection. After a new connect the audio connection should be re-established. BC01-um-001c Page 17 of 26 13 SENDING CUSTOM HCI COMMANDS. By editing Bluechat.HCI it is possible to add your own custom HCI commands these may be transmitted across the Bluetooth link. This is achieved by pulling down the HCI command menu by right clicking on the BlueChat toolbar and selecting “HCI commands” as shown above. 14 FLASH LOADER INSTRUCTIONS. The CASIRA Bluetooth Development kit is pre-configured with firmware on the BlueCoreT M chips that allows data and voice communication. When new firmware upgrades become available from CSR the user will need to install and use the Flash loader Program supplied with the system to upload the new firmware into the Systems Units. The Flash loader program “CSR_Flashloader” allows the user to download to the evaluation kit Flash memory. The first task of the program is to load into internal RAM a small boot loader that takes data from the UART and stores the data to the external Flash memory. Once the Flash upload is complete and verified the boot loader in RAM will be over written by the executed program. BC01-um-001c Page 18 of 26 14.1 Installing the CSR_Flashloader program. System Requirements for Installing the Flash Loader Application - Pentium processor-based personal computer - Microsoft WindowsT M98 or WindowsT M NT v4.0 (service pack 3.0 or later) - 16 MB of RAM (24 MB recommended) - 10 MB of available hard disk space which includes room for the Firmware binary files. Installation instructions 1. Insert the CASIRA Bluetooth Development kit CDROM into your CDROM drive. 2. From your CDROM run the “install.exe” file from the “software\host\CSR_Flashloader” folder which will created on your hard drive. 3. From your CSR_Flashloader directory create a shortcut for CSR_Flashloader.exe and place it on your desktop or taskbar as required for convenience. 4. Select close from the unzip menu to exit. 14.2 Connecting the SPI lead for Firmware updates. Before using the CSR_Flashloader program the SPI programming lead must be connected to the Evaluation module. Commence as follows: Remove all leads from the Evaluation module. Undo the three lid retaining screws in the base of the module. Connect the SPI programming lead to the connector marked “CN16 SIF”. Connect the other end of the lead to the PC printer port. Connect the DC connector to the “pwr” socket and verify the power LED is lit. BC01-um-001c Page 19 of 26 The unit is now ready for Flash Memory programming to commence.

The operation of the System Units can be unreliable when first operated. If the inquire or connect fails during the first BlueChat session it is necessary to stop and start the session again to correctly establish Bluetooth links (rather than repeatedly select the Connect or Inquire buttons). It some cases it is necessary to repeat this procedure until a connection is successfully established. 2. If a disconnect is made during a file transfer, the re-establishment of a connection can result in a failure of the BlueChat Session. 3. Repeated switching between Audio and Data Xfer types results in a failure of the BlueChat session. 4. If a failure of the BlueChat session occurs it is often necessary to cycle the power supply or push the (internal) reset button of the system unit as well as restart the BlueChat session BC01-um-001c Page 26 of 26
