TI BLE-Stack 2.03.03 Release Notes

Table of Contents


The BLE-Stack 2.03.03 is a set of sample applications, tools and protocol stack libraries that enables engineers to develop embedded Bluetooth® 4.2 LE applications on the SimpleLink™ CC1350 Bluetooth low energy (BLE) wireless MCU. A few examples of what can be created using the sample applications in this SDK include Bluetooth beacons incorporating the popular Apple iBeacon® and Eddystone™ formats, health and fitness monitors, dongles for cable replacement via a BLE Serial Port Bridge and industrial motor monitors.

Installation and Usage

Fixed Issues

Upgrade and Compatibility Information

The CC1350 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.

Operating System Support

The BLE-Stack sample applications in the CC1350 SDK are supported on the Microsoft Windows® 7 SP1 or later build platform.


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. Using a toolchain version or TI-RTOS version not listed below may result in compatibility issues with this SDK release.

Note: Earlier IDE/toolchain versions are not supported and compatibility with newer versions of supported IDEs is not assured.

Device Support

This release supports single-mode Bluetooth 4.2 LE on the following SimpleLink wireless MCU: CC1350

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: CC1350 LaunchPad
