Configuration

Please use redbear_blend2 ID for board option in “platformio.ini” (Project Configuration File):

[env:redbear_blend2]
platform = nordicnrf52
board = redbear_blend2

You can override default RedBearLab Blend 2 settings per build environment using board_*** option, where *** is a JSON object path from board manifest redbear_blend2.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:redbear_blend2]
platform = nordicnrf52
board = redbear_blend2

; change microcontroller
board_build.mcu = nrf52832

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

RedBearLab Blend 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_blend2]
platform = nordicnrf52
board = redbear_blend2

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).
