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
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.
Note:
Casira users should see the
Casira User Guide
for instructions on upgrading their firmware.
