1 Introduction _äìÉpìáíÉ» is a _äìÉ`çêÉ∆ development suite designed to help with your _äìÉíççíÜ∆ wireless technology development program and with all testing requirements for the BlueSlim 2 module. BlueSuite contains: ■ Graphical and command-line applications to configure, test and program the BlueCore device in your design. ■ The qêìÉqÉëí» Toolkit, a set of libraries for developing production test applications for your BlueCore enabled devices. ■ ■ Device drivers to communicate with BlueCore. Documentation to help development.This user guide explains: ■ ■ ■ The minimum system requirements in order to be able to run Bluesuite. See Section 2. How to install BlueSuite Section 3 and Section 4. The features and functions Bluesuite contains. See Section 7.
2 System Requirements Minimum system requirements for BlueSuite are: ■ ■ ■ Pentium processor based personal computer 64MB of RAM 20MB of available hard disk space 2.1 Operating System BlueSuite can be used on the following operating systems: ■ ■ ■ Microsoft Windows XP Service Pack 2 and later (not x64) Microsoft Windows Vista (not x64) Microsoft Windows 2000 Service Pack 3 and later (only for versions of BlueSuite prior to 2.0) See the release notes for testing information and detailed operating system requirements. 2.2 Software Required Your copy of BlueSuite comes with: ■ ■ Microsoft .NET Framework Version 2.0 Redistributable Package Visual C++ 2005 Redistributable PackageThe BlueSuite installer automatically installs these packages on your computer if they are missing.
3 Install BlueSuite Note: A bug in BlueSuite version 1.23 means that even if a later version of BlueSuite is installed, the version information for the USB driver may still indicate 1.23. If version 1.23 has previously been installed on the PC, unplug all CSR hardware, make sure you have the latest version of BlueSuite installed and run usbpurger from the BlueSuite installation directory. When a CSR BlueCore is plugged in, the Hardware Wizard prompts you for drivers. Run the BlueSuite installer and follow the instructions displayed by the setup wizard. By default the installer does a full installation, as shown in Figure 3.1. If you do not want to install all of the possible components, be sure that you install: ■ ■ ■ Drivers to allow SPI communication with the chip. You will need these to back-up your BlueCore device. USBDeviceDriver if you want to connect your device to your computer's USB port. DLL's, LIB's and headers to assist in production test if you want to do production testing. Figure 3.1: Full Installation of BlueSuite When you get to the Additional Tasks dialogue in Figure 3.2, you have to select the default debug transport. This configures the default behaviour of the BlueSuite programs. You can change this after installation by changing environment variable SPITRANS to LPT or USB. See Section 7.1
Figure 3.2: Additional Tasks Dialogue
4 Install a USB Driver BlueCore devices can be used with a USB host interface. The USB host interface is not a debugging interface and can be used by end users or in production modules. If you want to use the USB host interface to BlueCore, you must first configure your BlueCore for the USB host interface, and then install a USB device driver.
5 Firmware Overview CSR’s BlueCore ICs contain control software (called firmware). Firmware in BlueCores with flash can be updated using tools in BlueSuite: ■ ■ BlueFlash (see Section 7.2) is used during development to update your BlueCore's firmware using the Serial Peripheral Interface (SPI) debugging interface. TestFlash (part of TrueTest, see Section 8) can be used for the same purpose on the production line. DFUWizard (see Section 7.9) can sometimes be used to upgrade the firmware both in development and in the field. DFU (Device Firmware Upgrade) is a USB standard that allows end users to upgrade the BlueCore's firmware over the USB or UART (Universal Asynchronous Receiver Transmitter) interface. DFUWizard requires some firmware (the loader) to already be present in the device. The loader can only be updated by BlueFlash. The firmware version number is an important piece of information. You can identify your current firmware version using BlueFlash, see Section 7.2. 5.1 Firmware File Formats Table 5.1 describes the different firmware file formats you may encounter. File Extension(s) Description .xpv/.xdv The standard BlueCore firmware file format holds the binary data for firmware releases in two separate files, each of which hold part of the data. .xuv .xhv .dfu This firmware file format is one file containing the contents of both the .xpv file and the .xdv file. Chips with integrated flash have firmware files containing extra production information about the flash.File format for use with DFUWizard. Note: DFUTools, see Section 7.12, can convert .xpv and .xdv files into a .dfu file. Table 5.1: Firmware File Formats The .dfu file format is a flexible container format that can hold multiple different firmware images (for BlueCore2 and later chips) and multiple versions of the Persistent Store. This means you can have a universal .dfu file that works for multiple hardware devices. See BlueCore Device Firmware Upgrade Overview for a description of what DFU is and how it is used. 5.2 Persistent Store As well as containing the firmware image (i.e. control software), firmware files can also contain configuration information known as Persistent Store (PS). DFU files can contain information for a partial or full update of the PS. Any areas of the PS that are not in the DFU file will remain as they were before the update. Other firmware files cannot contain partial information; they either preserve or replace the PS.Firmware upgrades from the CSR support website do not contain any PS settings, thus the current settings are preserved. Firmware dumps that you make contain PS settings, and so will overwrite any existing ones if you upgrade using a previously dumped file.
Note: If firmware with no PS is downloaded onto a blank flash, a new PS is created on the flash memory using default values suitable for a Casira module. However, some keys require calibration per module for optimal performance. See pskeys.html in the firmware release for details on using individual PS Keys. Some of the same information is available by clicking the Describe button in PSTool, see the PSTool User Guide. 5.3 Firmware Build Types The Bluecore’s Bluetooth stack firmware comes in two forms, either containing the Bluetooth stack layers up to the Host Controller Interface (HCI) layer, or containing all the stack layers up to the Radio Frequency COMMunication (RFCOMM) layer. Since Firmware version 18, firmware builds are called Unified. They contain all the Bluetooth stack layers up to RFCOMM, but can be configured to present either an HCI interface, or an RFCOMM interface. The behaviour is controlled by PSKEY_ONCHIP_HCI_CLIENT, see the firmware release files for more information. All types of firmware builds can be held in any BlueCore firmware file format. 5.4 Upgrading Firmware Note: Casira users should see the Casira User Guide for instructions on upgrading their firmware. Go to the Bluetooth Firmware section on the CSR support website (www.csrsupport.com/BluetoothFirmware) to get the latest BlueCore firmware files. Use BlueFlash or DFUWizard to download the firmware to your BlueCore device.
6 Getting Started When you have connected your BlueCore device(s) to your computer, you can use BlueSuite tools to communicate with them. To test you have connected your BlueCore device(s) succesfully, you can use: ■ ■ The command-line tool btcli (Section 7.5). One of the graphical programs PSTool (See the PSTool User Guide) or BlueTest3 (See the BlueTest User Guide). 6.1 Exploring the Bluetooth Stack Use btcli if you want to explore the Bluetooth stack at all before starting development, as it provides a lower-level interface than the graphical programs in BlueSuite.The Bluetooth stack is described in the Specification of the Bluetooth System from www.bluetooth.com.
7 BlueSuite Programs This chapter describes the programs included in BlueSuite. The features of each program are briefly described and any relevant documentation is listed. Some programs without separate user guides are described in full detail.7.1 Transport Options for Command Line ToolsSome command line tools in BlueSuite take a -trans option, which controls the transport options. Table 7.1 indicates which variables can be used with each tool: Variable e2bluecmd/ pscli x Default SPI Description Example Values blueflashcmd CSRTRANS - - The transport to use SPI, USB, BCSP, H4 and H5 HCIPORT HCIBAUD x x autodetect if USB, otherwise COM1The port to use for the com1, com2, csr0 selected HCI transport if not CSRTRANS=SPI- 115200 The baud rate to use for 115200, 38400, etc. uart based HCI transportsSPITRANS SPIPORT x x x x LPT The SPI transport to use LPT, USB if CSRTRANS=SPI autodetect The port to use for the selected SPI transport■ ■ A LPT port number: 1, 2 etc. A USB-to-SPI converter's ordinal position: o, 1, 2.■ A USB-to-SPI converter's serial number (as printed on the converter e.g. 185920)SPIMUL Note: x x 0 The device to use if the 0, 1, etc. SPI port is multiplexed Table 7.1: Command Line Transport Options Where appropriate, BlueSuite tools attempts to prepend \\.\ to a string in HCIPORT. For example the name of a CSR USB device on WinXP is \\.\csr0; BlueSuite tools re-interpret csr0 as \\.\csr0. Examples To use USB-SPI (where 185920 is the serial number printed on the USB-SPI): -trans "CSRTRANS=SPI SPITRANS=USB SPIPORT=185920" (or just "SPITRANS=USB SPIPORT=185920") To use BCSP on COM1 at 38.4 kbaud: -trans "CSRTRANS=BCSP HCIPORT=com1 HCIBAUD=38400"It is possible to set these as Windows environment variables, which are then used as the default setting for a variable e.g. "set SPITRANS=USB" would change the default SPI transport from LPT-SPI to USB-SPI.
7.2 BlueFlash BlueFlash is a utility that allows you to download and upload firmware to and from the flash memory on the Casira modules or on your own BlueCore designs. As described in Section 5, there are several different firmware file formats, and firmware files may contain Persistent Store settings. Read Section 5.2 to make sure you do not accidentally change Persistent Store settings and to see which parts of BlueCore's firmware is updated by BlueFlash.Important Note: Do not erase the Persistent Store with Flash Erase (either by selection or via Full Erase) unless you are completely sure. Fully erasing the flash removes all Persistent Store settings. Use Full Erase only in the event that there may be a problem with the Persistent Store and you want to reload to a previous known working version. 7.2.1 User Interface BlueFlash opens with a user interface window, see Figure 7.1. Table 7.2 explains the function of each button or area. Figure 7.1: BlueFlash User Interface in Windows Vista
Button or Area Explanation Choose File Opens a dialogue box for selection of the firmware file to download to the flash on the BlueCore Module. You may open a .xpv, .xuv or .xbv firmware fileNote: If you open a .xpv file, the .xdv file must be present in the same folder. Edit If pressed, a message indicates that this is no longer supported. Download Copies the selected file to the flash on the BlueCore module. This process updates each flash block as required and verifies them in turn.Verify Compares the selected file with the code programmed into the flash on the BlueCore module. Verify only compares components contained in the file. The status area shows any reported differences.Status Provides a text report of the status of the current operation. Displays a visual indication of progress for the current operation. Progress Bar Start Processor Changes depending on the status of the processor. If it displays Stop Processor, the processor is running. It must be stopped before attempting to download code. When the new code has been loaded, the processor can be restarted by clicking Start Processor.Firmware ID Dump Identifies which version of firmware is currently loaded on the module. If BlueFlash is unable to identify the firmware version, you can still upgrade the firmware using this utility. Allows the user to dump the contents of the flash on the BlueCore module to a file. The data can be stored either as a pair of .xpv/.xdv files, as a combined .xuv file or as a raw binary file. The dumped file also contains all of the Persistent Store settings, allowing you to restore to a known firmware build and Persistent Store settings.Flash Erase File ID Provides options for erasing some or all of the flash memory including the Persistent Store area. Displays the name and version of firmware of the file selected for download on the module. Displays the name and location of the file selected for download. File Selection Flash Type Displays the type of flash memory that has been identified on the BlueCore module. Flash type is identified after you stop the processor. Different types of flash memory may have different memory block structures that require adjustments to BlueCore’s memory map. If the flash type indicates Unrecognised Flash assuming SST, either the flash on the BlueCore module is not supported, or there is a problem with the SPI connection. See Section 7.2.2.SPI Selection Allows the user to select the LPT or USB port to which the SPI cable is connected. About Indicates the version of the BlueFlash application in use. CSR advises using the most up to date version. Refer to the CSR support website for available updates.Table 7.2: Explanation of the BlueFlash User Interface
7.2.2 Troubleshooting BlueFlash Potential problems: ■ ■ If BlueFlash cannot identify the current build of firmware on BlueCore, check your firmware version. If BlueFlash cannot identify flash type, BlueFlash fails to stop processor or BlueFlash times out trying to make a connection to BlueCore, ensure that the following actions have been completed: ■ ■ Run InstParSpi.bat (C:\Program Files\CSR\BlueSuite\drivers) to copy and register the parspi.sys device driver, making sure you have administrative rights . Reboot your PC. Driver has been installed in the registry by looking for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Parspi■ ■ SPI cable is correctly connected Check for conflicts with other drivers, especially printer drivers (this includes the PDF converters). Conflicting printer drivers should be removed. To amend or remove a driver, select Printers and Faxes in the Control Panel and select File\Server Properties. Click on the Ports tab. Move the port to another location or delete the device. ■ Ensure that another SPI application is not trying to access the SPI port. SPI uses mutexes around port access, therefore another application may lock the port. Close all SPI based applications (use Task Manager if necessary) and retry. Reboot if necessary.7.2.3 BlueFlashCmd BlueFlashCmd is a command-line tool to download and upload firmware to flash memory on your BlueCore device. It can do everything BlueFlash does. Type BlueFlashCmd.exe -help for usage instructions. Note: Running BlueFlashCmd will reset your BlueCore chip 7.3 PSTool PSTool is an editing suite that allows you to read and modify the Persistent Store. The Persistent Store consists of configuration keys that modify the operation of the firmware. BlueCore is a very flexible device with many setup options. PS Keys must be set correctly for BlueCore to work in a particular design. Some PS Keys must be calibrated for each module. 7.3.1 PsCli PsCli is a command-line interface for reading and modifying the Persistent Store. Type pscli.exe -help to see usage instructions. 7.3.2 Documentation PSTool and pscli are described in the PSTool User Guide. See pskeys.html in the firmware release for details on using individual PS Keys. 7.4 BlueTest3 BlueTest3 is a program that enables you to execute BlueCore’s Built In Self Test (BIST) functions for RF testing. The BIST functions consist mainly of low level radio tests (transmitting a continuous wave at a prescribed frequency or receiving pseudo random data and calculating bit error rates). Included are tests for the PCM port and other internal blocks. 7.4.1 Documentation See the BlueTest User Guide.
7.5 BTCli Bluetooth Command Line Interface (BTCli) is a command-line program that lets you send Host Controller Interface (HCI) commands to your BlueCore device. Host computers use the HCI interface (part of the Bluetooth specification) to communicate with Bluetooth controllers (e.g. your BlueCore chip).See the BTCli User Guide for full details. 7.6 RFCli RFCli is a command line utility for communicating with RFCOMM firmware builds. It enables you to send and receive RFCOMM primitives to the chip (as well as other protocols). It also has a Tool Command Language (Tcl) interpreter built in so you can write scripts. See the RFCli User Guide for full details. 7.7 BCFMRadioImportant Note: Read the document referenced below before running this program, as you must configure your BlueCore device before this program will connect to it. BCFMRadio is a graphical tool for exercising the FM receiver on Bluecore5-FM. It is able to communicate with the Bluecore using I²C or BCCMDs using BCSP, H4, H4 Deep Sleep, H5, USB and SPI. BCFMRadio provides a user- friendly interface allowing configuration of the BlueCore5-FM radio.See Operating the BlueCore5-FM Radio Application Note. 7.8 E2BlueCmd E2BlueCmd is a command-line tool which can read and write from/to EEPROM to initialise the BlueCore EEPROM header, read and write blocks, and verify EEPROM contents against a file.E2BlueCmd works over the SPI interface. Type e2bluecmd -help for usage instructions. 7.9 DFU Wizard The DFU Wizard is a program for end users to upgrade the firmware on their BlueCore devices. 7.10 DFU Babel The USB to SPI Converter (or Babel) transforms the USB packets from the host computer to SPI signals sent out over Category 5 cable. DFU Babel is a program that lets you upgrade your USB to SPI Converter with new firmware. If CSR release a firmware upgrade for the USB to SPI Converter, you will be able to find it on www.csrsupport.com. See the USB-SPI Converter User Guide. 7.10.1 Upgrading The USB to SPI Converter FirmwareImportant Note: Do not attempt to upgrade a USB to SPI Converter with firmware designed for different hardware (e.g. Casira firmware). The USB to SPI Converter needs special firmware and any other firmware may make it permanently unusable. See the USB-SPI Firmware Upgrade Guide.
7.11 DFU ToolTips BlueSuite comes with DFU ToolTips, a shell extension that shows tool tips for DFU files in Windows. To see the tool tip, point the mouse over a DFU file, and wait for the tool tip to appear. Figure 7.2 shows a DFU tool tip. If the tool tip does not appear, you may have disabled tool tips in your version of Windows. To enable tool tips for files: 1. 2. 3. 4. 5. Go to the Control Panel Open Folder Options Select the View tab Scroll down the Advanced settings to Show pop-up description for folder and desktop items. Tick this box. Click OK DFU ToolTips also lets you right-click on a DFU file, and Download to BlueCore. This runs the DFU Wizard to download the DFU file to your BlueCore device. Figure 7.2: A DFU ToolTip7.12 DFU ToolsDFU Tools are a suite of command-line tools to let your sign and combine firmware and persistent store files to form DFU files. The DFU Tools documentation can be accessed from the Start Menu. Open the CSR BlueSuite item, and click CSR DFU Tools Documentation.
8 TrueTest Toolkit The TrueTest toolkit consists of the necessary libraries and documentation to let you develop applications in a variety of languages for production programming and testing of BlueCore enabled devices.The toolkit is designed for use in production test systems. Instead of writing test scripts to call other BlueSuite programs, you can write a test program that accesses the test APIs (Application Programming Interface) directly.See the TrueTest Toolkit Introduction.
