Release Information

The SimpleLink CC2640R2 Software Development Kit (SDK) delivers components that enable engineers to develop applications on the Texas Instruments SimpleLink Bluetooth low energy CC2640R2F wireless MCU. This powerful software toolkit provides a cohesive and consistent software experience for all SimpleLink CC2640R2F users by packaging essential software components such as the Bluetooth low energy (BLE) protocol stack, TI-RTOS kernel and TI Drivers in one easy-to-use software package along with exhaustive documentation.

This SimpleLink SDK enables development of single-mode BLE applications with either a Bluetooth 5 protocol stack (BLE5-Stack) supporting increased bandwidth to 2 Mbps (2x throughput as compared to Bluetooth 4.2) along with a demonstration of the LE Coded PHY feature for longer range data transmission, or a memory-optimized Bluetooth 4.2 protocol stack (BLE-Stack). Both protocol stacks are built on a common coreSDK which enables seamless application code portability across the SimpleLink MCU Platform. For a detailed description of the features available in each protocol stack, refer to the BLE5-Stack and BLE-Stack release notes in the Documentation Overview below.

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.
