u-blox EVK-NINA-B1¶

System¶

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 and are the most capable Bluetooth Smart SoCs on the market.

Configuration¶

Please use ublox_evk_nina_b1 ID for board option in “platformio.ini” (Project Configuration File):

[env:ublox_evk_nina_b1]
platform = nordicnrf52
board = ublox_evk_nina_b1

You can override default u-blox EVK-NINA-B1 settings per build environment using board_*** option, where *** is a JSON object path from board manifest ublox_evk_nina_b1.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:ublox_evk_nina_b1]
platform = nordicnrf52
board = ublox_evk_nina_b1

; change microcontroller
board_build.mcu = nrf52832

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading¶

u-blox EVK-NINA-B1 supports the next uploading protocols:

• jlink

• nrfjprog

• stlink

• blackmagic

• mbed

Default protocol is jlink

You can change upload protocol using upload_protocol option:

[env:ublox_evk_nina_b1]
platform = nordicnrf52
board = ublox_evk_nina_b1

upload_protocol = jlink

Debugging¶

PIO Unified Debugger - “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).

u-blox EVK-NINA-B1 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
