TI BLE-Stack 3.02.02.00 Release Notes
Table of Contents
Introduction
SimpleLink™ CC2640R2 Software Development Kit (SDK) delivers components that enable engineers to develop applications on Texas Instruments SimpleLink Bluetooth® low energy CC2640R2F wireless MCU. This powerful software toolkit provides a cohesive and consistent software experience for all SimpleLink CC2640R2 users by packaging essential software components such as the Bluetooth 4.2 protocol stack (BLE-Stack), integrated real-time localization system (RTLS), TI-RTOS and peripheral drivers in one easy-to-use software package along with exhaustive documentation.
As with all Bluetooth core specifications that support the low energy (LE) feature, devices implementing the LE feature of Bluetooth 4.2, are backward compatible with Bluetooth 4.1 and 4.0 LE capable devices.
Key features of BLE-Stack 3.02.02.00 :
- Support for all Bluetooth 4.2 LE features including LE Secure Connections and Data Length Extension (DLE)
- Integrated BLE Host and Controller supporting System-on-chip (SoC) standalone or network processor dual-device configurations
- Project Zero sample application demonstrates typical peripheral role operations such as controlling LEDs, identifying button states and sending strings of data from a smartphone to the LaunchPad™
- Standalone Peripheral, Broadcaster and Central sample applications to jump start development
- Full integration with TI-RTOS for real-time scheduling, automatic power management and utilizing peripheral device drivers
- Secure Over-the-Air Download (OAD) firmware upgrade support for updating device firmware wirelessly
- Free code development option with Code Composer Studio™ (CCS)
- Real Time Localization System integrated with Bluetooth Low Energy Stack
- Supports unlimited scan reporting to the application
BLE-Stack 3.02.02.00 is production release and a maintenance update to BLE-Stack 3.02.00.xx

Installation and Usage
- To build the sample applications with this SDK a supported a supported IDE must be installed (refer to Dependencies below)
- Install the simplelink_cc2640r2_sdk_2_40_00_xx.exe package on a Windows® 7 SP1, Windows 8.1 or Windows 10 machine with Administrator privileges
- The default install path is C:\ti\simplelink_cc2640r2_sdk_2_40_00_xx and is referenced as $BLE_INSTALL$ in the documentation
- Changing the default install path and/or drive letter may require updating project variables. Do not use a space in the install path
- It is recommended to make a backup of the installation in order to revert modifications to the SDK
Upgrade and Compatibility Information
The CC2640R2 SDK uses a new directory & file format which differs from BLE-Stack 2.2.x and earlier SDK releases. Existing applications developed with earlier SDKs require porting to this release; however, most BLE APIs remain the same thus reducing the effort required to migrate to this release. Refer to the Migration Guide for details.
Operating System Support
The BLE-Stack sample applications in the CC2640R2 SDK are supported on the Microsoft Windows® 7 SP1, Windows 8.1 or Windows 10 build platform.
Dependencies
The BLE-Stack sample applications were built & tested with the following Integrated Development Environments (IDEs) and listed components on Windows 7 SP1 and Windows 10 host build platforms.
Device Support
This release supports single-mode Bluetooth LE on the following SimpleLink wireless MCUs:
Note: This SDK does not support SimpleLink CC2640/CC2650/CC1350 devices or development kits with these devices.
Development Board Support
This release supports Bluetooth low energy applications on the following development kit: CC2640R2 LaunchPad
Validation
This release is for evaluation and development purposes only. End products being developed with this protocol stack version will require a future update prior to obtaining Bluetooth and/or regulatory certification.
Versioning
This product follows a version format, M.mm.pp.bb, where:
- M is a 1 digit major number,
- mm is a 2 digit minor number,
- pp is a 2 digit patch number,
