Programming with BlueNRG-1 system on chip

The BlueNRG-1 Bluetooth low energy (BLE) stack is provided as a binary library. A set of

APIs to control BLE functionality. Some callbacks are also provided for user applications to

handle BLE stack events. The user is simply requested to link this binary library to his or

her application and use the relevant APIs to access BLE functions and complete the stack

event callbacks to manage responses according to application requirements.

A set of software driver APIs is also included for accessing the BlueNRG-1 SoC peripherals

and resources (ADC, GPIO, I²C, MFTX, Micro, RTC, SPI, SysTick, UART and WDG).

The development kit software includes sample code demonstrating how to configure

BluenRG-1 and use the device peripherals and BLE APIs and event callbacks.

Documentation on the BLE APIs, callbacks, and peripheral drivers are provided in separate

documents.

Software directory structure

The BlueNRG-DK software package files are organized in the following directories:



Application: containing BlueNRG-1 Navigator and Flasher PC applications.



Doc: with doxygen BLE APIs and events, BlueNRG-1 peripheral drivers, BLE demo

applications, BlueNRG-1 Peripheral examples, BlueNRG-1 SDK and HAL driver

documentation, DK release notes and license file.



Firmware: with prebuilt binary BLE and peripheral driver sample applications.



Library



Bluetooth LE: Bluetooth low energy stack binary library and all the definitions of

stack APIs, stack events callbacks and constants. Over-the-air Bluetooth low

energy firmware upgrade support.





SDK_Eval_BlueNRG1: SDK drivers providing an API interface to the BlueNRG-1

platform hardware resources (LEDs, buttons, sensors, I/O channel).



HAL: Hardware abstraction level APIs for abstracting certain BlueNRG-1

hardware features (sleep modes, clock based on SysTick, etc.).



Project
