SimpleLink™ CC13x2_26x2 SDK 3.20.00.68 Release Notes
Table of Contents
Introduction
The SimpleLink™ CC13x2 and CC26x2 Software Development Kit (SDK) delivers components that enable engineers to develop applications on the Texas Instruments SimpleLink CC13x2 and CC26x2 family of wireless microcontrollers (MCUs). This software toolkit provides a cohesive and consistent software experience for all SimpleLink CC13x2 and CC26x2 wireless MCU users by packaging essential software components, such as a Bluetooth® Low Energy (BLE) protocol stack supporting Bluetooth 5, Thread 1.1 networking stack based on OpenThread, Zigbee 3.0 compliant protocol suite, RF-Proprietary examples, TI’s 15.4 Stack as well as the TI-RTOS kernel and TI Drivers in one easy-to-use software package along with example applications and documentation. In addition, the Dynamic Multi-Protocol Manager (DMM) software component enables multiprotocol development on a single SimpleLink wireless MCU through time division multiplexing.
The SimpleLink MCU portfolio offers a single development environment that delivers flexible hardware, software and tool options for customers developing wired and wireless applications. With 100 percent code reuse across host MCUs, Wi-Fi™, Bluetooth Low Energy, Sub-1GHz devices and more, choose the MCU or connectivity standard that fits your design. A one-time investment with the SimpleLink software development kit allows you to reuse often, opening the door to create unlimited applications. For more information, visit www.ti.com/simplelink.
This is version 3.20.00.68 of the SimpleLink CC13x2 / CC26x2 SDK.
Documentation
What’s New
BAW (Bulk Acoustic Wave) for crystal-less designs
- CC2652RB device support for Bluetooth Low Energy has been added into the SDK. The CC2652RB device has an integrated BAW (Bulk Acoustic Wave) resonator used to generate the RF carrier to eliminate the need for an external 48-MHz crystal. Therefore for this device, no external crystals are needed.
Bluetooth 5 (BLE5-Stack)
- Bluetooth 5.1 Feature: Angle of Arrival direction finding.
- TI Proprietary Time-of-Flight (ToF), which can protect against relay attacks, is now found in the RTLS example projects.
- Example projects for CC2652RB have been integrated into the SDK.
TI 15.4-Stack
- The TI 15.4-Stack example projects have been restructured to use a more intuitive framework
Zigbee (TI Z-Stack)
- Support for Secure OAD configuration
Easylink
- Internal flash OAD allows you to update the device firmware without using an external flash.
Dynamic Multi-protocol Manager (DMM)
- The DMM example projects have been restructured to use a more intuitive framework
Updated CoreSDK component to version 4.20.00.11. The CoreSDK is comprised of the TI-RTOS SYS/BIOS kernel, DriverLib and TI Drivers.

Known Issues
For 2.4 GHz operation on CC1352P, it is not possible to dynamically switch between the high power PA and the normal PA at runtime. Make sure you are only using one of the following TX power ranges:
- 15 to 20 dBm (using the high power PA) or
- -20 to 5 dBm (using the normal PA)
- For all SDK components, the importing of IAR projects through dev.ti.com is currently unsupported
Refer to the Document Overview for known issues and limitations as published in each SDK component’s release notes
