These examples and demos are for TI SimpleLink CC2640R2 SDK 1.40.00.45
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.
For other hardware and software resources, please visit our wiki. If you have any questions please refer to the FAQ page.
For extra examples for TI BLE-Stack 2.2.x SDK (CC26x0R1), see Branch: ble_examples-2.2.
The examples provided on this GitHub page serve as a plugin to a corresponding BLE-Stack SDK release. The master branch will always point to the latest release.
Older releases can be accessed by checking out/downloading their corresponding branch. For more information on supported examples please consult the readme.md of the desired branch/release.
Note: As of CC21640R2 SDK 1.35 and later the ble5apps component was added.
- ble5apps: Supports the Bluetooth 5 Core Specification and TI's BLE5-Stack.
- bleapps: Supports the Bluetooth 4.2 Core Specification and TI's BLE-Stack component.
For for more information about different SDK components, please consult the stack's User Guide.
Note: The version numbers below are related to GitHub ble_examples releases. The numbering scheme is in the form of M.mm.pp.bb. The fields pp.bb are incremented as GitHub examples are released, M.mm will map a GitHub release to a SimpleLink SDK release.

This repository can be cloned/download anywhere on your computer. There is a dependency between this repository and the SimpleLink CC2640R2 SDK install location.
By default the SimpleLink CC2640R2 SDK will install to:
C:\ti\simplelink_cc2640r2_sdk_1_40_00_45
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 v7.2.0 with TI ARM Compiler v16.09
- IAR for ARM v8.11.2
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.

This is a 2 part demo where a throughput_central and throughput_peripheral connect with one another, demonstrating the BLE5-Stack's 1 Mbps, 2 Mbps, 1+2 Mbps, and Coded PHYs.
- throughput_central
- throughput_peripheral
This is a 2 part demo where a longrange_central and longrange_peripheral connect with one another, demonstrating the BLE5-Stack's long range capabilities using the Coded PHY (S8).
- longrange_central
- longrange_peripheral
This is a 2 part example where a spp_ble_client and spp_ble_server connect with one another and exchange data over UART.
The demo supports Bluetooth 5 demonstrating the BLE5-Stack's new high speed 2Mbps PHYs:
- spp_ble_client
- spp_ble_server
The example also supports Bluetooth 4.2 demonstrating the BLE-Stack's Data Length Extension with OAD support:
- spp_ble_client
- spp_ble_server
This is an example that demonstrates the use and functionality of the ANCS. ANCS is a GATT service present on iOS devices used to retrieve and interact with iOS notifications.
This is script allows developers to evaluate the Voice over
HID-over-GATT-Profile (HoGP) profile which is demonstrated as part of the
voice_hogp_remote example. The voie_hogp_remote is available as part of the
Simplelink CC2640R2 SDK BLE Example Pack.
The voice.py Python script is compatible with Python 2 or Python 3 and depends
on the Windows® only pywinusb python
module. The script has been tested to work on a Window 10 host with a BLE 4.0
compatible BLE controller. For help on how to use the voice.py script, simply
invoke its help menu voice.py --help.
