TI BLE-Stack 2.03.11 Release Notes

Table of Contents


SimpleLink™ CC13x0 Software Development Kit (SDK) delivers components that enable engineers to develop applications on Texas Instruments SimpleLink Bluetooth® Low Energy CC13x0 wireless MCU. This powerful software toolkit provides a cohesive and consistent software experience for all SimpleLink CC13x0 users by packaging essential software components such as the Bluetooth 5.1 protocol stack (BLE-Stack), TI-RTOS and peripheral drivers in one easy-to-use software package along with exhaustive documentation.

Key features of BLE-Stack 2.03.11 :

As with all Bluetooth core specifications that support the Low Energy (LE) feature, devices implementing the LE specification of Bluetooth 5.1, are backward compatible with Bluetooth 4.2, 4.1 and 4.0 LE capable devices.

BLE-Stack Documentation

The SimpleLink CC13x0 SDK allows easier product development by combining the TI-RTOS and BLE protocol stack in one unified SDK. All BLE-Stack sample applications are based off the TI-RTOS Kernel. Key documents needed for BLE application development include:

What’s New

Known Issues and Limitations

Installation and Usage

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


The Bluetooth low energy software stack (BLE-Stack) for CC13x0 BLE enabled wireless MCUs uses Bluetooth Qualified Components, which allow customers to substantially reduce the testing required to meet Bluetooth end product listing (EPL) qualification requirements while providing flexibility to the device configuration. Bluetooth SIG rules specify that Qualified Components have a validity period of three (3) years at which time they may not be available for new End Product Listings (EPLs). For more information please refer to the application report SWRA601 - How to Qualify Your Bluetooth Low Energy Product.
