4.1 BlueFlash
BlueFlash is a utility that allows you to download and upload firmware to and from the flash memory on the Bluetooth modules .From Fig(2), we can insert SPI cable to connector , then link to parallel port of Host terminals (like Desktop PC , Notebook or Pocket PC)
Page 6
4.1.1 BlueFlash User interface BlueFlah opens with a user interface windows as Figure 4.1 indicates .
Figure 4.1: BlueFlash User Interface
The function of each button or area is described as follows:
Choose File: Opens a dialogue box for selection of the *.xpv file to download to the flash on the
BlueCore Module.
(Note: The .xdv file must be present in the same folder as the .xpv file. Edit: Opens a
hexadecimal-editing window. CSR recommends that you do not edit the *.xpv file in any way. If the code is edited, the Bluetooth protocol stack may behave erratically and it may no longer be Bluetooth qualified.)
Download: Downloads the selected file to the flash on the BlueCore module. This process will
update each flash block as required and verify them in turn.
Verify:Compares the selected file with the code programmed into the flash on the BlueCore
module. Any differences will be reported in the status area.
Status: Provides a text report of the status of the current download, upload or verify.
Activity Bar: Displays a visual indication of progress for the current download, upload or
verification.
Start Processor: Changes depending on the status of the processor. If it says Stop Processor, the
processor is running. It should be stopped before attempting to download code.Once the new code has been loaded, the processor can be restarted by clicking on Start
Page 7
Processor.
Firmware ID : Identifies which version of firmware is currently loaded on the module. BlueFlash
does not identify firmware created before Beta 10 release. If BlueFlash is unable to identify the firmware version, you will still able to upgrade the firmware using thi s utility.
Dump: Allows the user to download the contents of the flash to a file on the PC hard drive.
The data can be stored either as BlueCore .xpv/.xdv files or as a binary file. The file also contains all of the Persistent Store settings, allowing you to restore to a known firmware build and Persistent Store settings.
Flash Erase: Provides options for erasing some or all of the flash memory including the Persistent
Store area.
File ID : Displays the name and version of firmware of the file selected for download on the
module.
File Selection: This area displays the name and location of the file selected for download.
Flash Type: This area displays the type of flash memory that has been identified on the BlueCore
module. Flash type is identified when the processor is stopped. 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 5.1.3, Troubleshooting BlueFlash, for further information.
LPT Selection: This pull-down menu allows the user to select the LPT port to which the SPI cable is
connected.
CSR: This indicates the version of the BlueFlash application in use.

4.1.2 BlueFlash Firmware
There are four possible components in a firmware file:
l Stack: This is the main runtime code for BlueCore. There are two versions of stack, one
contains all stack layers up to HCI, plus an HCI version of the Virtual Machine (VM); the other contains stack layers up to HCI, plus L2CAP, RFCOMM, SDP and the Virtual Machine (an RFCOMM version). Both stack versions uses both program and data space.
l DFU Driver: Device Firmware Upgrade allows for updating the stack, Persistent Store and VM
application over the HCI transport. You cannot use a DFU operation to upgrade the DFU driver.
l Persistent Store: The Persistent Store holds all the setup and calibration information for
module .Most settings are design-specific, but some are module specific.
BlueFlash firmware is held in *.xpv files (which correspond to the program space) and *.xdv files (which correspond to the data space). There is a single *.dfu file for DFU. Not all file s contain all firmware components.
Downloading a firmware file only to flash memory overwrites the components contained in the file; all others remain intact. This affects only the calibration information in the Persistent Store. Downloading to flash memo ry ensures that you can return the module to a known calibrated state if the Persistent Store becomes corrupted beyond repair.
If firmware with no Persistent Store component is downloaded onto a blank flash, the stack code will create a new Persistent Store using default values suitable for use on a Casira module. However, some keys will require calibration per module for optimal performance.
The Verify function compares the contents of a firmware file to the contents of flash memory and reports any differences (comparing only components contained in the file).
Page 9
4.2 PSTools
PSTools 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.
Important Notes:
Do not modify Persistent Store values unless you have a clear understanding of what they do. Careless changes to the Persistent Store could prevent the firmware from executing correctly or can stop module from communicating with the PC.
4.2.1 Access Levels
PSTools has two customer access levels. At the higher access level, there are more PS Keys available for editing. The customer levels are:
l User: A minimum number of frequently used keys, e.g., UART baud rate l Developer: All the keys that a developer may need to modify
Page 10
4.2.2 PSTools Transport Interface
PSTools initially opens with a window that allows you to select the interface used to gain access to the Persistent Store. There are several transport interface options as follows: SPI BCCMD: We uses the BlueCore Command (BCCMD) Protocol running over the SPI transport layer to edit the Persistent Store. See Figure 4.2.
Important Note:
SPI BCCMD is the recommended method for editing the Persistent Store.
Figure 4.2: SPI BCCMD interface

4.2.4 PSTools User interface
Once the transport interface has been selected, PSTools opens with a user interface window, as shown in Figure
5.4. The function of each button or area is described as follows:
Persistent Store Key List: This window lists all of the PS Keys that are available at the current access
level.
Set: This button programs the values in the data area into the currently selected PS Key. Delete: This button removes a PS Key from the Persistent Store. If required, the stack will create the key
using a default value the next time the stack reboots. Otherwise, the key will continue to be reported in the status area as “Not present”.
Read: Clicking this button reads the value of the selected PS Key into the data area. A read is also
performed every time a new PS Key is selected.
resetting or if the transport was disrupted for any reason.
Reset BC: This button resets the BlueCore device. Any changes to the PS Keys will take effect only after
the device is reset and the stack reboots.
Close: This shuts down PSTools. Describe: This button brings up a description of the currently selected PS Key. Status Area : This area provides details such as PS Key number and Friendly Name or Programmer ID
plus the status of the transport interface. If this shows “Entry is not present” for a key that should always be present (such as the Bluetooth Address) then there are probably problems with the transport nterface.
Data Area : This area shows the data that is stored in the selected PS Key and allows you to edit it. Dump: This button allows you to save PS Keys as you choose. PS Keys can be retrieved through the Merge function. See Figure 5.4. Merge: This button opens PS Keys that were saved through Dump. See Figure 4.3 Edit Raw: This item allows you to change the default PS Key setting to one of your own preference (e.g.,
baud rate). Describe provides more information about each PS Key setting.

4.3 BlueChat2
BlueChat2 allows users to create an asynchronous connectionless link (ACL) between two devices to send text or a file and add a synchronous connection orientated (SCO) link for a voice connection between the two devices. Users can select between BCSP, H4 (UART), or USB host interfaces.
BlueChat2 was originally conceived as a demonstration/marketing tool. It is not Bluetooth compliant. It should be used only for demonstration and evaluation purposes.
Page 15
4.3.1 BlueChat2 User Interface
BlueChat2 opens with a user interface window, as Figure 4.4 indicates. The function of each button or area is described as follows:
Role: Selects the role for the device as either the master or the slave. Xfer Type: Selects which type of data is sent. Chat Link: Used to send and receive text data. Host Controller Interfac e Messages: HCI commands and responses are displayed here. Disconnect: Closes the link between the two devices. Connect: Establishes a connection to the selected device by setting up an ACL link. If Xfer Type is set to Audio, a SCO link is also created. Inquiry / Cancel Inquiry : If the device is the master, this button controls inquiry for other Bluetooth device
in the area. If the local device is selected to be the slave, this button will be greyed out.
Bluetooth Device Address: This lists the address of the local device and, in the pull-down selection box,
the addresses of any devices found during an inquiry. Use the selection box to highlight the Bluetooth device to which you wish to connect.
Figure 4.4: SPI BCCMD interface

File Transfer: Active when connected to another device and Xfer Type “Data” is selected. This displays
the name and the location of the file to be transferred. There are also status bars that show the progress of files that are being sent or received. Use the send button to start sending the data to the selected Bluetooth device.
Examples
To establish an ACL link:
1. Connect both Casira units to a PC (via their host interface).
2. Power up each Casira unit.
3. For each Casira, open a BlueChat2 utility and select the appropriate protocol and baud rates. The baud rate must be the same as the current setting of the PSKEY_UART_BAUD_RATE in the Persistent Store. Casira modules are supplied set to SP with a baud rate of 115.200kbps.
4. BlueChat2 will find the local device and display its Bluetooth Device Address in the Device On:
field.
5. The HCI window displays the HCI traffic used to configure the device.
6. Select the role of the device. Put one device into Master mode and one into Slav e mode.
7. Selecting the Master will allow the Inquire button to be used.
8. Selecting the Slave will put the device into Inquiry Scan mode to allow the Master to connect to
it.
9. On the Master’s BlueChat window, click the Inquire button and the Master will perform an inquiry
to find any slave devices in the area.
10. After the inquiry is finished (which should take about 20 seconds), the Master will show the
addresses of the Bluetooth devices it found during the inquiry. You can cancel the Inquiry at any time by clicking
Cancel Inquiry (any devices found before cancellation will display).
11. Select the address of the Bluetooth device you want to connect to in the Bluetooth Address
Box.
12. To connect, click on Connect.
13. After connecting, select Data in the Xfer type field.
14. You now should have a connection between the two devices. You can send messages
through the chat window or transfer files.
