The SimpleLink™ CC2640R2 Software Development Kit (SDK) includes the Texas Instruments royalty-free Bluetooth® low energy (BLE) software stacks for developing single-mode BLE applications on the ARM® Cortex®-M3 based SimpleLink Bluetooth low energy CC2640R2F wireless MCU. The BLE stacks are certified stacks that include all necessary software, sample applications and documentation to quickly get started with the development of single-mode Bluetooth low energy (BLE) applications. This SDK includes two components; one for developing Bluetooth 5 (BLE5-Stack) and one for Bluetooth 4.2 (BLE-Stack) applications. Both stacks support embedded and network processor applications and are backwards compatible with previous Bluetooth 4.1 and 4.0 specifications. Refer to the SDK release notes for a detailed description of the features available in this SDK.

To quickly get started with the CC2640R2 SDK, TI recommends using SimpleLink Academy, an interactive set of training labs with theory and hands-on exercises to rapidly begin development. The suggested starting point is Project Zero, an introductory demo to easily establish a link between CC2640R2F and a smartphone. Users can begin with Project Zero and launch their own Bluetooth low energy applications.

The SimpleLink™ MCU SDKs

The SimpleLink MCU SDKs feature common components and device-specific middleware to speed up your time-to-market and provide a unified development experience across the entire SimpleLink MCU portfolio of wired and wireless devices. Intuitive and standardized APIs enable 100% application code portability.

Common SimpleLink SDK components:

  • TI Drivers offer portable, feature-rich access to peripherals through easy-to-use functional APIs
  • DriverLib hardware abstraction layer (HAL) offer lower-level access for peripheral and device-specific optimization
  • OS/Kernel provides real-time, multi-tasking operation using the integrated TI-RTOS kernel, or other OS offerings such as FreeRTOS.
  • POSIX-compliant APIs enable application code portability between different OS/kernels
  • Examples are included in documentation and training to help you start developing

Middleware: Each device SDK incorporates additional middleware components to enable developers to take advantage of device-specific features and application-level libraries

Plugins: SDK plugins are also available to extend the functionalities of the SDK with protocols and software for external components.
