NUCLEO-WL55JC1

This is a LoRa radio board with a dual core STM32WL55JC MCU which contains both a Cortex-M4 and Cortex-M0+ CPU.

Two demo boards exist, the JC1 and JC2. The former is for high band RF and the latter low band RF.

Software

Software available for this board depends on a proprietary IDE and doesn't support GNU Make or cmake out of the box.

There are two version of the support package. One contains proprietary source code and is dated, the other only free to use source code and is maintained and kept up to date.

1.3.0

This version contains proprietary source files and requires an ST login to download.

Extract

unzip en.stm32cubewl-v1-3-0.zip

Github

Source code on github is maintained but lacks proprietary code. See the README section for a list of features removed.

Checkout

git clone --recursive https://github.com/STMicroelectronics/STM32CubeWL.git

Update

git pull
git submodule update --init --recursive

These are the features removed from the non proprietary version maintained at github

Application

Checkout the software package from github into the STM32CubeMX project directory as STM32CubeWL

Create an LoRAWAN end node which will default to the following connection parameters

EU_863_870 Default frequency plan for Europe
Link Layer TS001-1.0.4 + Regional Parameters RP002-1.0.1

Open STM32CubeMX
Go to Load project
Navigate to STM32CubeWL/Projects/NUCLEO-WL55JC/Applications/LoRaWAN/LoRaWAN_End_Node
Open LoRaWAN_End_Node.ioc
Go to Project Manager
Change toolchain to Makefile
Change MCU and Firmware Location to the checkout directory STM32CubeWL
Setup LoRaWAN commissioning (LoRaWAN/App/se-identity.h)
Generate code (ignore message about Platform settings)

At this point the project can be built using `make'

make
