TI BLE-Stack 2.03.03 Release Notes

Table of Contents

Introduction

The BLE-Stack 2.03.03 is a set of sample applications, tools and protocol stack libraries that enables engineers to develop embedded Bluetooth® 4.2 LE applications on the SimpleLink™ CC1350 Bluetooth low energy (BLE) wireless MCU. A few examples of what can be created using the sample applications in this SDK include Bluetooth beacons incorporating the popular Apple iBeacon® and Eddystone™ formats, health and fitness monitors, dongles for cable replacement via a BLE Serial Port Bridge and industrial motor monitors.

BLE-Stack Documentation

The new SimpleLink CC1350 SDK allows easier product development by combining the TI-RTOS and BLE protocol stack in one unified SDK. All BLE-Stack sample applications are based off the TI-RTOS Kernel. Key documents needed for BLE application development include:

• Quick Start Guide
• Developer’s Guide
• BLE-Stack APIs
• Software Manifest

What’s New

• Port to MCPI compliant SDK

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_cc13x0_sdk_2_20_00_xx.exe package on a Windows® 7 SP1 or later machine with Administrator privileges
• The default install path is C:\ti\simplelink_cc13x0_sdk_2_20_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

Fixed Issues

• Device sometimes fails to return to standby during ADV or Connection Events
• GAPBOND_SECURE_CONNECTION_ONLY not enforced when pairing with peer devices requesting legacy pairing
• CC13XX TX power defines are not correct in BTool for the HCIExt_SetTxPower API

Upgrade and Compatibility Information

The CC1350 SDK uses a new directory & file format which differs from BLE-Stack 2.2.x and earlier SDK releases. Existing applications developed with earlier SDKs require porting to this release; however, most BLE APIs remain the same thus reducing the effort required to migrate to this release.

Operating System Support

The BLE-Stack sample applications in the CC1350 SDK are supported on the Microsoft Windows® 7 SP1 or later build platform.

Dependencies

The BLE-Stack sample applications were built & tested with the following Integrated Development Environments (IDEs) and listed components on Windows 7 SP1 and Windows 10 host build platforms. Using a toolchain version or TI-RTOS version not listed below may result in compatibility issues with this SDK release.

• IAR Embedded Workbench: EWARM-8.20.2
• TI Code Composer Studio: CCS-8.1
• TI-RTOS for CC13XX: 3.60.01.00
• C Compiler for ARM: 18.1.2.LTS
• XDCTools: 3.50.07.20

Note: Earlier IDE/toolchain versions are not supported and compatibility with newer versions of supported IDEs is not assured.

Device Support

This release supports single-mode Bluetooth 4.2 LE on the following SimpleLink wireless MCU: CC1350

Note: This SDK does not support SimpleLink CC2640/CC2650/CC1350 devices or development kits with these devices.

Development Board Support

This release supports Bluetooth low energy applications on the following development kit: CC1350 LaunchPad

Known Issues and Limitations

• Number of simultaneous connections may be limited when attempting concurrent LE Secure Connections pairings. Suggested workaround is to perform LE Secure Connections pairing on an individual connection basis.
• BTool GUI may not be displayed or scaled correctly on Windows 10 machines
• Debugging CCS v8 projects may generate a spurious “unknown register” error which can be ignored
• Calling GAP_DeviceInit twice may result in a “Invalid LMP Parameters” event which can be safely ignored
• The Simple Network Processor (SNP) and L2CAP Connection Oriented Channels (L2CAP COC) are not available in this release, support will be added in a future update
• CCS Cloud™ is not supported in this release
• Cache-As-RAM project configurations are experimental
• Post-release updates to Known Issues will be posted on the TI BLE Wiki

Validation

TI BLE-Stack 2.03.03 was tested using the following components:

• TI-RTOS for CC13XX: 3.60.01.00
• C Compiler for ARM: 18.1.2.LTS
• XDCTools: 3.50.07.20
• CC1350 LaunchPad
