TI BLE5-Stack 2.00.03.00 Release Notes
Table of Contents
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™ CC13x2 and CC26x2 family of wireless MCUs. 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 2.00.03.00 is an updated production release for the CC13x2_26x2 wireless MCU and it supports LE Coded PHYs and Advertising Extensions.
BLE5-Stack 2.00.03.00 has been Bluetooth 5 qualified and is available for production use.
Key features of BLE5-Stack 2.00.03.00 :
- Initial Bluetooth 5 qualified release for production
- 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
- Secure Over-the-Air Download (OAD) firmware upgrade support for updating device firmware wirelessly
- Free code development option with Code Composer Studio™ (CCS)
- All example applications now utilize the BLE5-Stack in ROM to maximize application flash memory availability
- Simple_central supports up to 32 concurrent connections
- Secure Boot and Secure Over-the-Air Download (OAD) firmware upgrade support for updating device firmware wirelessly

BLE5-Stack Documentation
The SimpleLink CC13x2 and CC26x2 Software Development Kit(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_cc13x2_26x2_sdk_3_10_01_xx installer package on a supported host operating system build machine with Administrator privileges
- The default install path for Windows is C:\ti\simplelink_cc13x2_26x2_sdk_3_10_01_xx and is referenced as $BLE_INSTALL$ in the documentation
- 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
What’s New
| ID | Summary |
|---|---|
| BLE_AGAMA-391 | [SysConfig] Add BLE RF Settings Configuration to Sysconfig |
| BLE_AGAMA-387 | BLE Examples re-structure & Using Examplegen to Generate the BLE Simple Example Applications |
| BLE_AGAMA-384 | [SysConfig] Add Applications user-configurable pre-processor defines to SysConfig |
| BLE_AGAMA-383 | [SysConfig] Add more Bond Manager Configurations to SysConfig |
| BLE_AGAMA-121 | Support L2CAP PDU size larger than 255 |
Fixed Issues
| ID | Summary |
|---|---|
| BLE_AGAMA-300 | Known issue where queued param updates in slave device cause application assert |
| BLE_AGAMA-141 | IAR: The global custom.argvars and local ble project custom.argvars cannot coexist together |
Known Issues and Limitations
| ID | Summary |
|---|---|
| BLETOOLS-213 | AE and legacy advertising sets number is limited to 20 |
| BLESTACK-3843 | RTOS logging of certain high-priority events, such as SWIs and HWIs, may interfere with reception of a scan response chain |
| BLE_AGAMA-547 | Simple Peripheral Application freeze when selecting “Work With” when connected to 3 or more central devices |
| BLE_AGAMA-546 | Simple Central: No connection timeout when connection is unsuccessful |
| BLE_AGAMA-139 | When using multi-role, there exists an issue where a random address will display instead of the “Work With” selection in the serial terminal |
| BLE_AGAMA-80 | The NV Driver is now used for SNV record & bond storage. It is not possible to retain OSAL SNV contents when upgrading from earlier BLE5 1.1.x releases. Two flash pages of NV are required. |
Upgrade and Compatibility Information
The BLE5-Stack 2.00.03.00 only supports SimpleLink CC13x2 and CC26x2 devices with silicon revision E. No support for previous silicon revisions or LaunchPad™ development kits using earlier silicon revisions. If you’re unsure of the revision number of your device, please see the Package Symbolization and Revision Identification section of the Errata Note.
Contrary to previous releases, this SDK supports both CC13x2 and CC26x2 devices and associated LaunchPad development kits.
