Bluetooth LE host stack and applications

The Bluetooth LE Host Stack component provides an implementation for a Bluetooth 5.3 mandatory and some optional, proprietary, and experimental features. The Bluetooth LE Host Stack component provides application examples, services, and profiles.

Main features supported:

  • Automotive Compliance

  • MISRA Compliance

  • HIS CCM <= 20

  • Advanced Secure Mode

  • Enhanced ATT

  • GATT Caching

  • Bluetooth LE Host GCC Libraries

  • Bluetooth LE Host IAR Libraries

  • Bluetooth LE Host Peripheral Libraries

  • Bluetooth LE Central Libraries

  • Bluetooth LE Host Full Host Features Libraries

  • Bluetooth LE Host Optional Features Libraries

  • Bluetooth LE Host Mandatory Features Libraries

  • Bare-metal and FreeRTOS Support

  • Bluetooth LE Privacy Support

  • NCP Mode - FSCI Application

  • CCC Sample Applications

  • Enhanced Notifications

  • Dynamic Database

  • OTA Support - Sample Applications

  • Decision based Advertising Filtering (DBAF) - Experimental feature

  • Advertising Coding Selection (ACS) - Experimental feature

  • Periodic Advertising with Responses (PAwR) - Experimental feature

  • Encrypted Advertising Data (EAD) - Experimental feature

    Note: For evaluating experimental features, replace the Bluetooth LE Host default example projects libraries with the libraries from the SDK folder ..\middleware\wireless\bluetooth\host\lib_exp and enable the features in the application. The Radio Subsystem (NBU) Firmware with experimental features is required.

Note: Project configurations that require usage of the Bluetooth LE controller including all Bluetooth LE examples require the Radio Subsystem (NBU) Firmware to be re-programmed with the firmware provided in the SDK under middleware\wireless\ble_controller\bin. See the EVK Quick Start Guide and Secure Provisioning SDK (SPSDK) documentation for NBU programming step.

Note: Project configuration enabling Experimental features requires the Radio Subsystem (NBU) Firmware to be reprogrammed with the firmware provided in the SDK under \middleware\wireless\ble_controller\bin\experimental\. For NBU programming steps, see the EVK Quick Start Guide and Secure Provisioning SDK (SPSDK) documentation.

Connectivity framework

The Connectivity Framework is a software component that provides hardware abstraction modules to the upper layer connectivity stacks and components. It also provides a list of services and APIs, such as, Low power, Over the Air (OTA) Firmware update, File System, Security, Sensors, Serial Connectivity Interface (FSCI), and others. The Connectivity Framework modules are located in the middleware\wireless\framework SDK folder.
