Release Information

This is version 2.2.7 of the TI Bluetooth® low energy protocol stack Software Development Kit (SDK). The BLE-Stack SDK allows for the development of single-mode Bluetooth low energy (BLE) applications on TI's first generation SimpleLink Bluetooth low energy CC2640 and Multi-Standard CC2650 wireless microcontroller units (MCUs) supporting version 5.1 of the Bluetooth specification with features defined by version 4.2 of the Bluetooth specification. The CC26x0 family of wireless MCUs includes a 32-bit Arm® Cortex™-M3 as the main application CPU running at 48 MHz, a dedicated Cortex-M0 processor for the radio / Physical Layer (PHY), and an autonomous Sensor Controller Engine for low-power sensing applications. The BLE protocol stack is built on top of the TI Real-time Operating System (TI-RTOS) which provides advanced power management and flexible peripheral driver capabilities allowing the development of highly optimized and power efficient standalone or network processor applications. The TI-RTOS SDK is installed during the BLE-Stack SDK installation.

Version 2.2.7 of the BLE-Stack is a maintenance update to TI's existing royalty-free Bluetooth low energy software protocol stack which is certified for Bluetooth specification version 5.1. This release includes support for all core specification version 4.2 Low Energy (LE) features as well as several development kits. This protocol stack update is in addition to support of all major Bluetooth LE core specification version 4.1 features, including support for up to 8 master or slave BLE connections. Please note that no Bluetooth 5 or Bluetooth 5.1 features are supported. A few examples of what can be created using the sample applications in this SDK and/or the additional resources found in the Examples section below include Bluetooth beacons incorporating the popular Apple iBeacon® and Eddystone™ formats, glucose, heart rate and fitness monitors, dongles for cable replacement via a BLE Serial Port Bridge and industrial motor monitors.

See What's New section for an overview of the changes included in this release. The Bluetooth core specification version 4.2 features supported in this release allow development of the most secure and power efficient products incorporating the Bluetooth low energy specification.
