Introduction
The BLE5-Stack is a set of sample applications, tools, APIs and protocol stack libraries that enable engineers to develop Bluetooth ® 5 standalone or network processor LE applications on the SimpleLink™ CC2640R2 Bluetooth Low Energy (BLE) wireless MCU. This Bluetooth 5 (BLE5-Stack) release includes support to enable development of applications using the following Bluetooth 5 LE features: High Speed, Long Range (LE Coded PHYs), Advertisement Extensions as well as all existing Bluetooth 4.0, 4.1 and 4.2 LE features.
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.
BLE5-Stack 1.01.11.00 has been Bluetooth qualified and is available for production use.
Key features of BLE5-Stack 1.01.11.00 :
- Supports the following Bluetooth 5 LE features: High Speed Mode (2 Mbps PHY), Long Range (LE Coded 125kbps and 500kbps PHYs), Advertisement Extensions (AE) non-periodic, Privacy 1.2.1 and Channel Selection Algorithm #2
- Support for all Bluetooth 4.2 LE features including LE Secure Connections and Data Length Extension (DLE)
- Integrated BLE Host and Controller supporting System-on-chip (SoC) standalone or network processor dual-device configurations
- Project Zero sample application demonstrates typical peripheral role operations such as controlling LEDs, identifying button states and sending strings of data from a smartphone to the LaunchPad™
- Standalone Peripheral, Broadcaster and Central sample applications to jump start development
- Full integration with TI-RTOS for real-time scheduling, automatic power management and utilizing peripheral device drivers
- Free code development option with Code Composer Studio™ (CCS)

BLE5-Stack Documentation
The SimpleLink CC2640R2 SDK allows easier product development by combining TI-RTOS and the BLE protocol stack in one unified SDK. All BLE5-Stack sample applications are based off the TI-RTOS Kernel. Key documents needed for BLE application development include:
Installation and Usage
- To build the sample applications with this SDK a supported a supported IDE must be installed (refer to Dependencies below)
- Install the simplelink_cc2640r2_sdk_4_30_00_xx installer package on a supported host operating system build machine with Administrator privileges
- The default install path for Windows is C:\ti\simplelink_cc2640r2_sdk_4_30_00_xx
- Changing the default install path and/or drive letter may require updating project variables. Do not use a space in the install path
- It is recommended to make a backup of the installation in order to revert modifications to the SDK

Known Issues and Limitations
| ID | Summary |
|---|---|
| BLETOOLS-14 | [BTool App] Discovered devices list is never cleared |
| BLESTACK-5121 | host_test app with peripheral and observer cannot be built due to memory limitation |
| BLESTACK-5120 | host_test app with central and broadcast cannot be built due to memory limitation |

| BLESTACK-2711 | Issue when Scanning for extended advertisements using the 2M PHY |
Upgrade and Compatibility Information
The BLE5-Stack 1.01.11.00 introduces new BLE API which breaks compatibility with BLE5-Stack 1.1.x and earlier BLE-Stack releases. Refer to the included porting guide for migrating applications developed with prior TI BLE protocol stack versions.
Qualification
The Bluetooth low energy software stack (BLE-Stack) for CC2640R2 BLE enabled wireless MCUs uses Bluetooth Qualified Components, which allow customers to substantially reduce the testing required to meet Bluetooth end product listing (EPL) qualification requirements while providing flexibility to the device configuration. Bluetooth SIG rules specify that Qualified Components have a validity period of three (3) years at which time they may not be available for new End Product Listings (EPLs). This SDK release is covered by QDID 118740 with expiration date 2021-10-13 and TCRL-2017-2. For more information please refer to the application report SWRA601 - How to Qualify Your Bluetooth Low Energy Product.
Operating System Support
- Microsoft Windows® 7 SP1, Windows 8.1 or Windows 10
- Ubuntu 14.04 64-bit, Ubuntu 16.04 64-bit
- macOS Mojave
Dependencies
