Safety recommendations

5 Safety recommendations

5.1 Targeted audience

This product targets users with at least basic electronics or embedded software development knowledge such as

engineers, technicians, or students. This board is not a toy and is not suited for use by children.

5.2 Handling the board

This product contains a bare printed circuit board and like all products of this type, the user must be careful about

the following points:

•The connection pins on the board may be sharp, be careful when handling the board to avoid hurting

yourself

•This board contains static sensitive devices. To avoid damaging it, handle the board in an ESD‑proof

environment.

•While powered, do not touch the electric connections on the board with your fingers or anything conductive.

The board operates at a voltage level that is not dangerous, but components may be damaged when

shorted.

•Do not put any liquid on the board and avoid operating the board close to water or at a high humidity level.

•Do not operate the board if dirty or dusty.

Quick start

6 Quick start

This section describes how to quickly start development using NUCLEO-WB55RG.

To use the product, the user must accept the Evaluation Product License Agreement from the www.st.com/

epla webpage. For more information on the STM32WB Nucleo-64 board and demonstration software, visit the

www.st.com/stm32nucleo webpage.

Before the first use, make sure that no damage has occurred to the board during shipment:

•All socketed components must be firmly secured in their sockets.

•Nothing must be loose in the board blister.

The Nucleo board is an easy-to-use development kit to quickly evaluate and start development with an STM32

microcontroller in a QFN48 package.

6.1 Getting started

Follow the sequence below to configure the STM32WB Nucleo-64 board and launch the demonstration

application (Refer to Figure 3 for component location):

1. Check jumper positions on board: JP2, JP3, JP4, and JP6 ON, JP1 (Power source) on USB_STL, all JP5

jumpers ON except for GND.

2. Install the STMicroelectronics Bluetooth® Low Energy sensor mobile application on a Bluetooth® Low

Energy compatible mobile device from App Store® or Google Play™.

3. Connect the Nucleo board to a PC with a USB Type-A or USB Type-C® to Micro-B cable through CN15 USB

ST-LINK connector. Once powered on, the LD2 green LED blinks for each advertising interval –timeout after

one minute.

4. Use the STMicroelectronics Bluetooth® Low Energy sensor mobile application to detect the STM32WB P2P

server (P2PSRV1) and connect it. Once connected, the LD2 green LED blinks for each connection interval.

The smartphone application displays the device's service and characteristics.

5. Pushing the B1 button on the board toggles the alarm on the smartphone display. Pushing the B2 button

changes the connection interval (50 ms, 1 s). The effect is visible directly on the LD2 green LED of the

Nucleo board. On the smartphone, push the lamp to switch ON or OFF the Nucleo board LD1 blue LED. For

more details, refer to the user manual STM32CubeWB Nucleo demonstration firmware (UM2551).

6. The demonstration software and several software examples showing how to use the STM32 Nucleo features

are available from the NUCLEO-WB55RG product location.
