RedBearLab BLE Nano 2¶

Hardware¶

Platform Nordic nRF52: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor and are the most capable Bluetooth Smart SoCs on the market.

Configuration¶

Please use redbear_blenano2 ID for board option in “platformio.ini” (Project Configuration File):

[env:redbear_blenano2]
platform = nordicnrf52
board = redbear_blenano2

You can override default RedBearLab BLE Nano 2 settings per build environment using board_*** option, where *** is a JSON object path from board manifest redbear_blenano2.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:redbear_blenano2]
platform = nordicnrf52
board = redbear_blenano2

; change microcontroller
board_build.mcu = nrf52832

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading¶

RedBearLab BLE Nano 2 supports the next uploading protocols:

• jlink

• nrfjprog

• stlink

• blackmagic

• cmsis-dap

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:redbear_blenano2]
platform = nordicnrf52
board = redbear_blenano2

upload_protocol = cmsis-dap

Debugging¶

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

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

RedBearLab BLE Nano 2 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
