General Information
– Device Information Service v1.1 (DIS_SPEC_V11r00)
– Battery Service v1.0 (BAS_SPEC_V10)
• The KeyFobDemo project has been updated to use the adopted battery service. The custom battery
service that was used in previous released has been removed.
• The TimeApp project has been updated to include support for the Phone Alert Status Profile
(PASP_SPEC_V10) in the Client role.
• Support for "Production Test Mode" has been added, allowing a Bluetooth Low Energy application in a
"single-chip" configuration to temporarily expose the HCI over the UART interface when triggered
externally to do so (e.g. hold a GPIO pin low during power up). This allows the device to be connected
to a Bluetooth tester in order to run direct test mode (DTM) commands on a production line using the
final release firmware, while leaving the UART GPIO pins available for the application to use at all
other times
• A Universal Boot Loader (UBL) using the USB Mass Storage Device (USB-MSD) class has been
added along with a Serial Boot Loader (SBL). The HostTestRelease project includes configurations
with examples of both boot loaders. The SBL project is included with the installer. More information on
the UBL can be found in the following document: C:\Texas Instruments\BLE-CC254x-1.2\Documents\
Universal Boot Loader for SOC-8051 by USB-MSD Developer's Guide.pdf
• HCI extension command HCI_EXT_MapPmIoPortCmd added to support toggling of a GPIO line as
CC254x device goes in and out of sleep. This command can be used to automatically control the
bypass line of the TPS62730 DC/DC converter for reducing power consumption in an optimized
manner.
• A slave device will now dynamically widen it's Rx window when a previous connection event was
missed. This improves connection stability by accounting for additional clock drift that may have
occurred since the last successful connection event.
• The application now has the capability to change the permissions of the device name in the GAP
service by calling GGS_SetParameter and changing the value of the parameter
GGS_W_PERMIT_DEVICE_NAME_ATT. The application can also receive a callback when a client
device writes a new name to the device. The application registers the callback by calling
GGS_RegisterAppCBs. The prototype for GGS_RegisterAppCBs can be found in gapgattserver.h.
Bug Fixes:
• Duplicate filtering now works with combination states.
• Various minor application / profile bug fixes.
Known Issues:
• Use of the NV memory (to save application data or Bluetooth Low Energy Host bonding information)
during a Bluetooth Low Energy connection may cause an unexpected disconnect. The likelihood of this
happening increases with frequent usage, especially when using short connection intervals. The cause
is related to the NV wear algorithm which at some point may cause an NV page erase which can
disrupt system real-time processing. It is therefore recommended that the NV memory be used
sparingly, or only when a connection is not active.

Version 1.1b Nov 30, 2011
Notices:
• This version of the Texas Instruments Bluetooth Low Energy stack and software includes support for
the CC2541, as well as some minor enhancements and bug fixes. Details of these can be found below.
The general software architecture remains the same as in the v1.1 and v1.1a releases.
Changes and Enhancements:
• Bluetooth Low Energy stack libraries for the CC2541 are included.
• All Bluetooth Low Energy libraries are renamed and now indicate whether they are used for CC2540 or
CC2541.
