SimpleLink™ CC13x2_26x2 SDK Release Notes

Table of Contents


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
