TI BLE5-Stack 1.02.01.00 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 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 1.02.01.00 is an updated evaluation, non-production release for the CC13x2 wireless MCU.
Key features of BLE5-Stack 1.02.01.00 :
- 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
- Over-the-Air Download (OAD) firmware upgrade support for updating device firmware wirelessly
- Free code development option with Code Composer Studio™ (CCS)

BLE5-Stack Documentation
The SimpleLink CC13x2 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_sdk_2_20_00_71 installer package on a supported host operating system build machine with Administrator privileges
- The default install path for Windows is C:\ti\simplelink_cc13x2_sdk_2_20_00_71 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 |
|---|---|
| None | None |
Fixed Issues
| ID | Summary |
|---|---|
| BLESTACK-3840 | Fixed an issue where some smartphones would disconnect when switching to the 2M PHY if the suggested Data Length Extension TX values were not the maximum 251 bytes / 2120 us |
| BLESTACK-3478 | Fixed an issue where a connection could drop if a LL connection parameter update request reject indication is received during a connection |
Known Issues and Limitations
| ID | Summary |
|---|---|
| BLESTACK-3844 | 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 |
| BLESTACK-3842 | 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. |
| BLESTACK-3813 | Simple Central:start RSSI reading sometimes receive RSSI –127 dbm |
| BLESTACK-3530 | Connections drops when using a central device to connect to 8 SimpleBLEPeripherals |
| BLESTACK-2958 | When using multi-role, there exists an issue where a random address will display instead of the “Work With” selection in the serial terminal |
| BLESTACK-2446 | IAR: The global custom.argvars and local ble project custom.argvars cannot coexist together |
Upgrade and Compatibility Information
