These examples and demos are for TI SimpleLink CC2640R2 SDK 1.35.00.33

This repository contains experimental Bluetooth® 5 and Bluetooth® 4.2 Low Energy sample applications for Texas Instruments' SimpleLink CC2640R2 SDK. These examples have not been validated as production-ready.

Do not use GitHub's bug tracking feature for support. For inquiries, see the Bluetooth® low energy Forum.

To use the examples and tools in this repository, please download and install the SimpleLink CC2640R2 SDK first, and if necessary buy an evaluation kit.

If the Simplelink CC2640R2 SDK must be installed to a different location, then see the FAQ page for IDE specific instructions for changing environment variables.

Similar to the Simplelink CC2640R2 SDK, the examples in this repository support the CCS and IAR toolchains. Please pay careful attention to versions of these tools, the supported version are listed below. Using a non supported version is untested and may result in unexpected behavior.

• CCS v7.1.0 with TI ARM Compiler v16.09
• IAR for ARM v7.80.3

For more information on toolchain setup, please refer to our FAQ page.

The FAQ page will try to address some of the common questions related to the ble_examples repo.
