Overview

The p-nucleo-wb55 is a multi-protocol wireless and ultra-low-power device embedding a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy (BLE) SIG specification v5.0 and with IEEE 802.15.4-2011 board. It integrates an ARM Cortex-M4 STM32WB55RG microcontroller with 256KB of RAM and 1MB of ROM Flash.

Flashing the device

The ST p-nucleo-wb55 board includes an on-board ST-LINK programmer and can be flashed using OpenOCD (use version 0.11.0 at least).

To flash this board, just use the following command:

make BOARD=p-nucleo-wb55 flash -C examples/hello-world

STDIO

STDIO is available via the ST-Link programmer.

Use the term target to open a terminal:

make BOARD=p-nucleo-wb55 -C examples/hello-world term
