## Hardware

Platform Nordic nRF51: The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

Microcontroller | NRF51822
Frequency | 16MHz
Flash | 256KB
RAM | 32KB
Vendor | RedBearLab

## Configuration

Please use `redBearLabBLENano` ID for board option in “platformio.ini” (Project Configuration File):

    [env:redBearLabBLENano]
    platform = nordicnrf51
    board = redBearLabBLENano

You can override default RedBearLab BLE Nano 1.5 settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest redBearLabBLENano.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:redBearLabBLENano]
    platform = nordicnrf51
    board = redBearLabBLENano

    ; change microcontroller
    board_build.mcu = nrf51822

    ; change MCU frequency
    board_build.f_cpu = 16000000L

## Uploading

RedBearLab BLE Nano 1.5 supports the next uploading protocols:

- `blackmagic`

- `cmsis-dap`

- `jlink`

- `mbed`

- `nrfjprog`

- `stlink`

Default protocol is `cmsis-dap`

You can change upload protocol using upload_protocol option:

    [env:redBearLabBLENano]
    platform = nordicnrf51
    board = redBearLabBLENano

    upload_protocol = cmsis-dap

## Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

RedBearLab BLE Nano 1.5 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools | On-board | Default
--- | --- | ---
Black Magic Probe |  |
CMSIS-DAP | Yes | Yes
J-LINK |  |
ST-LINK |  |

## Frameworks

Name | Description
--- | ---
Arduino | Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.

Mbed

The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.

Zephyr | The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind.
