BL654 Development Kit
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 which makes them quite capable Bluetooth Smart SoCs.

Configuration
Please use laird_bl654_dvk ID for board option in “platformio.ini” (Project Configuration File):
[env:laird_bl654_dvk]
platform = nordicnrf52
board = laird_bl654_dvk
You can override default BL654 Development Kit settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest laird_bl654_dvk.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:laird_bl654_dvk]
platform = nordicnrf52
board = laird_bl654_dvk
; change microcontroller
board_build.mcu = nrf52840
; change MCU frequency
board_build.f_cpu = 64000000L
Uploading
BL654 Development Kit supports the following uploading protocols:
blackmagiccmsis-dapjlinkmbednrfjprogstlink
Default protocol is jlink
You can change upload protocol using upload_protocol option:
[env:laird_bl654_dvk]
platform = nordicnrf52
board = laird_bl654_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).
BL654 Development Kit has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
