Release Notes
Version 1.3.2
June 13, 2013
Notices:
- This version of the Texas Instruments BLE stack and software is a minor
update to the v1.3.1 release. It contains some minor bug fixes and a few
functional changes.
- The BLE protocol stack, including both the controller and host, was
completely retested for v1.3.2. The profiles Running Speed and Cadence,
Cycling Speed and Cadence, and Glucose were fully tested and passed
certification. Other profiles with no code changes since 1.3.1 were sanity
tested only.
Changes and Enhancements:
- Added Running Speed and Cadence profile and service. An example application
demonstrating running speed and cadence is provided.
- Added Cycling Speed and Cadence profile and service. An example application
demonstrating cycling speed and cadence is provided.
- Added delay before performing Connection Parameter changes. Implemented
conn_pause_peripheral) and TGAP(conn_pause_central) timers as described in
CSA 3 rev 2, Gap Connection Parameters Changes, Section 1.12. Updated
HIDAdvRemote, HIDEmuKbd, KeyFob, SensorTag, and SimpleBLEPeripheral
applications.
- Update Privacy Flag and Reconnection Address characteristics permissions
(Erratum 4202)
- A new Windows USB CDC driver has been included in the installer. This new
driver is signed and is functional on Windows 8 systems.
Bug Fixes:
- Some minor updates to glucose sensor and collector were made.
- The gyroscope would draw continuous 6mA when enabled. The updated
code now performs a read and turns off the gyro after 60ms.
- The master抯 host would accept invalid connection parameters requested
by the Slave, and would send back the Connection Parameter Update Response
with 憄arameters accepted? The host now performs validation on these
parameters.
- When coming out of sleep, the HCI_EXT_ExtendRfRangeCmd would override
HCI_EXT_SetRxGainCmd setting and set it to default gain. This has been fixed.
Known Issues:
- Use of the NV memory (to save application data or BLE Host bonding
information) during a BLE 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.
- HCI packet size of 128 bytes or more will be disregarded by the stack, and as
such, no HCI event will be returned.
- The HAL SPI driver that was implemented since the v1.3 release can sometimes
hang, particularly in cases in which power management is used and when there
is heavy traffic on the SPI bus.

Version 1.3.1
April 18, 2013
Notices:
- This version of the Texas Instruments BLE stack and software is a minor
update to the v1.3 release. It contains some minor bug fixes, with no major
functional changes. It also contains two additional projects for the CC2541
Advanced Remote Control Kit.
- Since none of the profile source code was significantly changed since the
v1.3 release, no additional re-testing of the profiles and sample
application were done for v1.3.1. The only exception is the HID-over-GATT
profile, which was fully re-tested for this release. The BLE protocol stack,
including both the controller and host, was completely retested for v1.3.1.
Major Changes and Enhancements:
- The GAP parameter TGAP_LIM_ADV_TIMEOUT now uses units of seconds instead
of milliseconds.
- The HidAdvRemote Project has been added. This implements a full mouse-like
pointing functionality using motion and gesture control. The project runs on
the CC2541 BLE Advanced Control included as part of the CC2541DK-REMOTE kit.
The application implements the HID-over-GATT (HOGP) profile with a report
descriptor supporting the keyboard, mouse, and consumer control classes of
HID devices.
- The HidAdvRemoteDongle project has been added. This application runs on the
CC2540USB dongle, and implements partial functionality of HID-over-GATT
(HOGP) host with a fixed report descriptor to match that of the descriptor
of the HidAdvRemote Project. This means that the HidAdvRemoteDongle was
designed only to work with with the HidAdvRemote, and will not be compatible
with any other HOGP devices. This project was created to allow users who
are using a host device that does not have native Bluetooth Smart Ready
support and/or does not have HOGP support to use the BLE Advanced Remote
Control with their system.
- For GAP central role applications, the bond manager now properly handles
cases in which the peripheral device has erased previously stored bonding
infomration.
- A new HCI extension API has been added to allow peripheral/slave devices to
temporarily ignore any nonzero slave latency value, and explicitly wake up
at every connection event regardless of whether it has any data to send.
The prototype for the API function HCI_EXT_SetSlaveLatencyOverrideCmd can
be found in hci.h, including the description of the function.
- A new HCI extension API has been added to allow the application layer to
get or set a build revision number.
Bug Fixes:
- In some cases L2CAP Peripheral Connection Parameter Update requests failed
due to a zero value in the transmitWindowOffset parameter when the
connection was initially established. This has been fixed and updates
should now work succesfully.
- During bonding, connection failures would occasionally occur due to the
OSAL Simple NV driver performing a page compaction and halting the CPU for
longer than the time required for the link layer to maintain proper
connection timing. To prevent this from occurring, the simple NV driver now
has any API to force a page compaction if the page is full beyond a specified
threshold. The bond manager calls this API everytime a connection is
terminated to ensure that compaction occurs before the next connection is set
up.
- Occasional slave connection failures would previously occur in cases in which
the master device sends Update Channel Map requests while a large slave
latency value is in use. This has been fixed.
- The SensorTag application now properly supports storage of GATT Client
Characteristic Configuration Descriptor values with bonded devices.
- After disabling advertising, the CC254x would unecessarily wake up for a
short period of time 500ms later. This unecessary wake-up has been removed.
- Upon Power-On Reset or after wake-up from PM3, a 400ms delay has been
implemented, during which time the CC254x will not go into PM2 sleep. This
allows time for the 32kHz crystal to stabilize. Previously, in rare cases
with certain hardware configurations the CC254x could have timing issues due
to the crystal not having time to stabilize.
- Minor bug fixes to GlucoseSensor and GlucoseCollector projects.
Known Issues:
- Use of the NV memory (to save application data or BLE Host bonding
information) during a BLE 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.
- HCI packet size of 128 bytes or more will be disregarded by the stack, and as
such, no HCI event will be returned.

is heavy traffic on the SPI bus.

Version 1.3
Dec 12, 2012
Notices:
- This version of the Texas Instruments BLE stack and software features several
changes, enhancements, and bug fixes from v1.2.1. Details of these can be
found below.
Changes and Enhancements:
- A new sample project, SensorTag, has been added. This application runs on the
CC2541 Sensor Tag board, which is included as part of the CC2541DK-SENSOR
development kit. The application includes custom services for an
accelerometer, barometer, gyro, humidity sensor, IR temperature sensor, and
magnetometer.
- A new Boot Image Manager (BIM) is included. This allows one CC2540 or CC2541
device to contain two separate software images (an "A" image and a "B" image)
stored in flash. Upon power-up, the BIM selects which image to boot into.
This can be based on criteria such as the state of a GPIO pin, or based on a
selection from the previously running application upon reset.
- A new Over-the-air firmware download (OAD) feature is included. The feature
allows a peer device (which could be a central BT Smart device such as a
smartphone) to push a new firmware image onto a peripheral device and update
the firmware. This feature uses the BIM, in which case the downloaded image
gets stored in the opposite flash location as the currently running image.
For example, if the "A" image is the current image and is used to perform the
download, then the downloaded image becomes the "B" image. Upon reset, the
"B" image with the updated firmware would be loaded. The OAD feature
optionally allows for the firmware image to be signed (using AES). Both the
SensorTag and SimpleBLEPeripheral projects include configurations for using
the OAD feature. A central "OADManager" application is also included,
demonstrating a central implementation for sending a new firmware image to an OAD target device.
- The physical HCI interface used by the network processor (HostTestRelease)
has been enhanced to work while power management is enabled on the CC254x
device. The UART interface, when using RTS and CTS lines, can be used by an
external application processor to wake-up the CC254x network processor. When
the network processor has completed all processing, it will go into deep
sleep. In addition to UART, an SPI interface has been added as an option for
the physical HCI interface. It also supports power management by means of
the MRDY and SRDY lines.
- The CC2541 configuration of the KeyFobDemo project has been modified to
support the new CC2541 keyfob hardware, contained in the CC2541DK-MINI kit.
The accelerometer has been changed, and a TPS62730 DC/DC converter has been
added.
- The structure of all projects have been changed to include a Transport Layer
("TL") library and network processor interface "NPI" source code. This new
architecture allows for non-network processor applications to have slightly
reduced code size by removing unnecessary stack components.
- An API has been provided allowing the device name and appearance
characteristics in the GAP service to be modified by the application layer.
- KeyFobDemo project now includes visual feedback from LED to indicate when
device has powered up and when device is advertising.
- The HID-over-GATT Pofile (HOGP) implementation has been updated to now
queue up HID report and send notifications upon reconnection to a HID host.
- A new implementation of the HID service has been included, which supports
a combined keyboard, mouse, and consumer class device in its HID report
descriptor.
- The API for sending L2CAP Connection Parameter Update Requests from the GAP
Peripheral Role Profile has been updated to take both the requested minimum
and maximum connection intervals as parameters.
- BTool has been enhanced with a new GATT explorer table, displaying discovered
attributes, handles, and values. An XML file is included which allows the
user to define descriptions of characteristics based on their UUIDs.
- HCI UART interface baud rate has been changed from 57600 to 115200.
Bug Fixes:
- When power management is used with long connection intervals (>2s), the
CC254x remains sleeping properly without unnecessary wake-ups.
- When slave latency is used, peripheral devices now properly wake-up before
the next connection event when a data packet is queued
- Various bug fixes on the GlucoseSensor and GlucoseCollector projects to
improve compliance with profile and service specifications.
- HID-over-GATT Pofile (HOGP) implementation has been updated to provide
better interoperability with HID hosts.
Known Issues:
- Use of the NV memory (to save application data or BLE Host bonding
information) during a BLE 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.
- HCI packet size of 128 bytes or more will be disregarded by the stack, and as
such, no HCI event will be returned.

Version 1.2.1
Apr 13, 2012
Notices:
- This version of the Texas Instruments BLE stack and software is a minor
update to the v1.2 release. It contains some minor enhancements and bug
fixes, with no API changes or major functional changes.
Changes and Enhancements:
- When advertising is enabled by calling GAP_MakeDiscoverable, the first
advertisement event will now occur within a few milliseconds, rather than
waiting for 10ms.
Bug Fixes:
- The HidEmuKbd project now properly implements the HID Service include of the
Battery Service. This bug fix allows for proper interoperability between the
CC254x HID Profile and host systems running Windows 8.
- The source code file hal_board_cfg.h has been updated to better support the
serial bootloader (SBL) and Universal Bootloader (UBL).
- Scanning in BTool can now be cancelled at any time without hanging or
freezing the system.
Known Issues:
- Use of the NV memory (to save application data or BLE Host bonding
information) during a BLE 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
