• The new CC2640R2L device is a low-cost alternative to CC2640R2F.
• Refer to the Document Overview for the individual release notes and details for starting development with each SDK component
• SimpleLink platform level changes are available in SimpleLink Core SDK Release Notes

Description

Important Note: The SimpleLink SDKs are updated regularly.

This SDK includes TI’s royalty-free Bluetooth® Low Energy (BLE) software stacks with all necessary software, example applications and documentation to quickly get started with the development of single-mode Bluetooth Low Energy applications.

Two Bluetooth qualified protocol stack components are included, one for developing with advanced Bluetooth 5 (BLE5-Stack) featured, and one for memory-optimized Bluetooth 5.1 applications (BLE-Stack), using features defined by the Bluetooth 4.2 specification. Both stacks support embedded and network processor configurations and are backwards compatible with previous Bluetooth 4.2 and earlier Bluetooth specifications.
