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 and automotive qualified SimpleLink Bluetooth low energy CC2640R2F-Q1 wireless MCU. The BLE stacks 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.
