Configuration

Please use laird_bl653_dvk ID for board option in “platformio.ini” (Project Configuration File):

[env:laird_bl653_dvk]
platform = nordicnrf52
board = laird_bl653_dvk

You can override default BL653 Development Kit settings per build environment using board_*** option, where *** is a JSON object path from board manifest laird_bl653_dvk.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:laird_bl653_dvk]
platform = nordicnrf52
board = laird_bl653_dvk

; change microcontroller
board_build.mcu = nrf52833

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

BL653 Development Kit supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • mbed

  • nrfjprog

  • stlink

Default protocol is jlink

You can change upload protocol using upload_protocol option:

[env:laird_bl653_dvk]
platform = nordicnrf52
board = laird_bl653_dvk

upload_protocol = jlink

Debugging

Debugging - “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).

BL653 Development Kit has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
