The SimpleLink™ CC2640R2 Software Development Kit (SDK) includes the Texas Instruments royalty-free Bluetooth® Low Energy (BLE) software stacks for developing single-mode Bluetooth LE applications on the Arm® Cortex®-M3 based SimpleLink Bluetooth Low Energy CC2640R2F wireless MCU, SimpleLink Bluetooth Low Energy CC2640R2L wireless MCU, and automotive qualified SimpleLink Bluetooth Low Energy CC2640R2F-Q1 wireless MCU. These Bluetooth LE protocol stacks include all necessary software, example applications and documentation to quickly get started with the development of single-mode Bluetooth Low Energy applications. This SDK includes two Bluetooth qualified protocol stack components; 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. 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 starting with SimpleLink Academy, an interactive set of training labs with theory and hands-on exercises to rapidly begin application development. The suggested starting point in SimpleLink Academy is the BLE Fundamentals lab, which uses the Project Zero example application on the CC2640R2 LaunchPad™ development kit to establish a link between CC2640R2F and a smartphone to perform tasks such as controlling LED states and monitoring for button press notifications over a Bluetooth LE connection.
