Nordic nRF51 Dongle (PCA10031)¶

Hardware¶

Platform Nordic nRF51: The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

Configuration¶

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

Uploading¶

Nordic nRF51 Dongle (PCA10031) supports the following uploading protocols:

• cmsis-dap

• jlink

• 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¶

Debugging - “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).

Nordic nRF51 Dongle (PCA10031) has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
