UM2435 Hardware layout and configuration

7.3 Getting started

7.3.1 Conventions

Table 3 provides the definition of some conventions used in this document.

7.3.2 Quick start

The pack board is a low-cost and easy-to-use development kit to quickly evaluate and start

a project based on an STM32WB microcontroller featuring a 2.4 GHz RF transceiver

supporting Bluetooth

specification v5.0 and IEEE 802.15.4-2011 PHY and MAC in a

VFQFPN68 or UFQFPN48 package.

1. Before installing and using the product, accept the Evaluation Product License

Agreement from www.st.com/stm32nucleo.

2. For correct identification of all device interfaces from the host PC, install the Nucleo

USB driver available on www.st.com/ stm32nucleo before connecting the board.

3. Set correctly the jumper JP1 ([7-8] on USB STL).

4. Plug the Nucleo USB ST-LINK connector (P2P server) and USB dongle (P2P client) to

power sources. On the P2P server, you will see a blinking LED for approximately

minute.

5. Once the P2P client is powered, push the SW1 button to start scanning (it will

automatically connect to the P2P server).

6. Once connected, the green LED blinks for each connection interval. The P2P client

searches for the P2P service, LEDs and buttons characteristics, and enables

notification.

7. Pushing the SW1 button toggles the blue LED on the remote device.

8. Pushing the SW2 button on the Nucleo Board changes the connection interval (50 ms,

s). The effect is visible directly on the green LED of the Nucleo board.

9. The demonstration software and several software examples that make it possible to

use the STM32 Nucleo and USB dongle features are available at

www.st.com/ stm32nucleo.

10. Develop your own application using the available examples.

7.3.3 Default boards configuration

By default the board is set in SMPS mode. It is possible to set the board In LDO mode, see

Section 7.13: Jumper configuration.
