Introduction
The BLE5-Stack is a set of sample applications, tools, APIs and protocol stack libraries that enable engineers to develop Bluetooth ® 5 standalone or network processor LE applications on the SimpleLink™ CC13xx and CC26xx family of wireless MCUs.
This Bluetooth 5 (BLE5-Stack) release includes qualification for Bluetooth 5.2 in addition to support for the existing core specifications (4.0, 4.1, 4.2) in addition to core specification 5.0 and 5.1 LE features such as: Direction Finding (AoA - Connected and Connectionless CTE), High Speed Mode (2 Mbps PHY), Long Range (LE Coded 125kbps and 500kbps PHYs), Advertisement Extensions (AE), Periodic Advertisements, Privacy 1.2.1 and Channel Selection Algorithm #2.
As with all Bluetooth core specifications that support the Low Energy (LE) feature, devices implementing the LE feature of Bluetooth 5 are backward compatible with Bluetooth 4.2, 4.1 and 4.0 LE capable devices.
BLE5-Stack 2.02.06.00 has been Bluetooth 5.2 qualified and is available for production use.

BLE5-Stack Documentation
The SimpleLink CC13xx and CC26xx Software Development Kit (SDK) allows easier product development by combining TI-RTOS and the Bluetooth LE protocol stack in one unified SDK. Key documents needed for Bluetooth LE application development include:
Installation and Usage
- To build the sample applications with this SDK a supported Integrated Development Environment (IDE) must be installed (refer to Dependencies below)
- Install the simplelink_cc13xx_cc26xx_sdk_6_20_00_xx installer package on a supported host operating system build machine with Administrator privileges
- The default install path for Windows is C:\ti\simplelink_cc13xx_cc26xx_sdk_6_20_00_xx
- 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
What’s New
- Deprecated and removed support for UART driver, in favor of UART2 in all cases except in BLE5-Stack’s NPI.

Upgrade and Compatibility Information
The BLE5-Stack 2.02.06.00 only supports SimpleLink CC13xx and CC26xx devices with silicon revision E. No support for previous silicon revisions or LaunchPad™ development kits using earlier silicon revisions. If you’re unsure of the revision number of your device, please see the Package Symbolization and Revision Identification section of the Errata Note.
As a supplier of Bluetooth® Low Energy (LE) solutions with a focus on interoperability and broad market adoption, we recommend to transition from proprietary Real Time Localization Toolbox (RTLS) software examples to the new RTLS software examples based on the Bluetooth 5.2 specification. These examples are included in this software development kit. For further information please contact your local TI sales representative.
Qualification
The Bluetooth Low Energy software stack (BLE5-Stack) for CC13xx_CC26xx Bluetooth LE-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 information on the applicable QDID’s for this release, please refer to the application report SWRA601 - How to Qualify Your Bluetooth Low Energy Product.
As mentioned in the Known Issues and Limitations section, the Bluetooth low energy software stack (BLE5-Stack) for CC13xx_CC26xx CTE reception and transmission for AoA on the 2M PHY is not fully compliant with the Bluetooth specifications. As a consequence, AoA enabled projects cannot be qualified to operate on the 2M PHY.
