Please use nrf51_dongle ID for board option in “platformio.ini” (Project Configuration File):
[env:nrf51_dongle]
platform = nordicnrf51
board = nrf51_dongle
You can override default Nordic nRF51 Dongle (PCA10031) settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest nrf51_dongle.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:nrf51_dongle]
platform = nordicnrf51
board = nrf51_dongle
; change microcontroller
board_build.mcu = nrf51822
; change MCU frequency
board_build.f_cpu = 32000000L
Nordic nRF51 Dongle (PCA10031) supports the next uploading protocols:
cmsis-dap
jlink
mbed
nrfjprog
Default protocol is jlink
You can change upload protocol using upload_protocol option:
[env:nrf51_dongle]
platform = nordicnrf51
board = nrf51_dongle
upload_protocol = jlink
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).
Nordic nRF51 Dongle (PCA10031) has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
