STM32WB Build Bluetooth® LE Project

1 Presentation

This page describes how to easily build and install STM Bluetooth® LE SIG example application.
Example projects can be found on STM32CubeWB MCU Package[1], and are available for different platforms.

Some of the following information can be retrieved from Building wireless applications with STM32WB Series microcontrollers, application note[2].

2 Requirements

2.1 Software and system requirements

The software required are as follows:
minimum IDEs version:

  • IAR embedded workbench for ARM (EWARM) toolchain V8.20.2
  • RealView microcontroller development kit (MDK-ARM) toolchain V5.31
  • STM32CubeIDE toolchain V1.7.0 [3]


  • STM32CubeProgrammer[4]: to flash the board with an already generated binary

2.2 Hardware requirements

A Nucleo board[5], an STM32WB USB dongle[5], or an STM32WB Discovery Kit[6] is necessary to install the application.

More details about the board and other hardware requirement are available in the Bluetooth® LE SIG and 802.15.4 Nucleo pack user manual[7].

3 Build and install the application

This section describes the build process using IAR and STM32CubeIDE.


Select the application you want to build, open the IAR (EWARM) dedicated directory and launch the project.eww IAR file to open the demonstration project on IDE.

Ensure your project is correctly visible into the Project Explorer view.

Build your project by reproducing the following steps:

IAR: build

3.2 STM32CubeIDE

Select the application you want to build, open the STM32CubeIDE dedicated directory and launch the Cube IDE .project of the demonstration.

3.3 Install the application from STM32CubeProgrammer

It is possible either to flash the previously build binary using STM32CubeProgrammer software[8].

Select your device and connect to it:

Once connected, the device information is displayed on Cube Programmer interface. Click on the programming icon, in the left column, and select the project binary to flash:

  • STM32Cube_FW_WB_V[...]\Projects\[...]\Applications\BLE\BLE_p2pServer\[...]\ BLE_p2pServer.hex

Then, click ok Start Programming button:
