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 2.01.02.00 has been Bluetooth 5 qualified and is available for production use.
Key features of BLE5-Stack 2.01.02.00 :
- Real-Time Localization System (RTLS) support, including Bluetooth 5.1 Direction Finding (AoA)
- Bluetooth 5.1 qualified release for production
- Supports the following Bluetooth 5 LE features: High Speed Mode (2 Mbps PHY), Long Range (LE Coded 125 kbps and 500 kbps 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

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_4_10_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_cc13x2_26x2_sdk_4_10_00_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-1850 | [RTLS] Remove ToF support from SDK |
| BLE_AGAMA-1793 | Added 1/3 wire Wi-Fi CoEx interface support |

Fixed Issues
| ID | Summary |
|---|---|

| BLE_AGAMA-1708 | [RTLS] AoA multiple connection: When>4 slaves are connected, the master node might disconnect after aoa_start command is sent. WA requires delaying the aoa_start command for a few seconds after the connection is established. |
| BLE_AGAMA-1707 | Fixed a BLE Stack DoS (crash) vulnerability caused by invalid connection PDU parameters |
| BLE_AGAMA-1692 | Radio quits transmitting and receiving when enabling 3+ connections and advertising and scanning at the same time. |
| BLE_AGAMA-1613 | Sending connection update request fails when the device has previously been rejected |
| BLE_AGAMA-1597 | [RTLS] AoA Master sometimes get stuck in multiple connections scenario |
| BLE_AGAMA-1587 | Receiving a connection request packet with transmit window offset = 0 will fail. |
| BLE_AGAMA-1573 | [SYSCFG] Custom Board configuration in sysconfig is not supported |
| BLE_AGAMA-1448 | When using slave latency, the connection is often dropped with 1 phone, and sometimes dropped with multiple phones connected to central device |
| BLE_AGAMA-741 | Gracefully handle ATT_ERR_UNSUPPORTED_REQ |
Known Issues and Limitations

Upgrade and Compatibility Information
The BLE5-Stack 2.01.02.00 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.
As a supplier of Bluetooth® Low Energy (BLE) solutions with a focus on interoperability and broad market adoption, we recommend to transition from proprietary Real Time Localization Toolbox (RTLS) software examples to the new RTLS software examples based on the Bluetooth 5.1 specification. These examples are included in this software development kit. For further information please contact your local TI sales representative.
Qualification
