Arduino Core for STM32WB based boards

What is it ?

ArduinoCore-stm32wb is targeted at ultra low power scenarios, sensor hubs, with BLE connectivity.

Supported boards

Tlera Corp

STMicroelectronics

Installing

Board Manager

  1. Download and install the Arduino IDE (at least version v1.8.13)
  2. Start the Arduino IDE
  3. Go into Preferences
  4. Add https://grumpyoldpizza.github.io/ArduinoCore-stm32wb/package_stm32wb_boards_index.json as an "Additional Board Manager URL"
  5. Open the Boards Manager from the Tools -> Board menu and install "Tlera Corp STM32WB Boards"
  6. Select your STM32WB board from the Tools -> Board menu

OS Specific Setup

Linux
  1. Go to ~/.arduino15/packages/TleraCorp/hardware/stm32wb/<VERSION>/drivers/linux/
  2. sudo cp *.rules /etc/udev/rules.d
  3. reboot
Windows
STM32 BOOTLOADER driver setup for Tlera Corp boards
  1. Plugin STM32WB board and toggle the RESET button while holding down the BOOT button
  2. Go to %AppData% and navigate from to AppData\Local\Arduino15\packages\TleraCorp\hardware\stm32wb\<VERSION>\drivers\windows
  3. Right-click on STM32Bootloader.bat and select Run as administrator
ST-LINK driver setup for NUCLEO boards
  1. Plugin NUCLEO board
  2. Download and install ST-Link USB Drivers

From git (for core development)

  1. Follow steps from Board Manager section above
  2. cd <SKETCHBOOK>, where <SKETCHBOOK> is your Arduino Sketch folder:
  • OS X: ~/Documents/Arduino
  • Linux: ~/Arduino
  • Windows: Documents\Arduino
  1. Create a folder named hardware, if it does not exist, and change directories to it
  2. Clone this repo: git clone https://github.com/grumpyoldpizza/ArduinoCore-stm32wb.git TleraCorp/stm32wb
  3. Restart the Arduino IDE

BLE / Wireless stack firmware installation

STM32WB uses encrypted/signed firmware images for the BLE stack. Please flash the FWUpdate sketch under the STM32WB examples before using BLE. The update will take up few seconds/minutes. During that time the LED will stay on, while the serial monitor will say disconnected. When done the LED will blink if the update was succesful, or simply be turned off if an error was encountered. The serial monitor should pop up again and report back the newly updated firmware versions. The FWInfo sketch can be used to verify what version is installed. At this time it should report back 1.10.0 for the BLE stack.

Recovering from a faulty sketch for Tlera Corp Boards

Sometimes a faulty sketch can render the normal USB Serial based integration into the Arduindo IDE not working. In this case plugin the STM32WB board and toggle the RESET button while holding down the BOOT button and program a known to be working sketch to go ack to a working USB Serial setup.
