P-NUCLEO-LRWAN2 / P-NUCLEO-LRWAN3 firmware overview

The

P-NUCLEO-LRWAN2

and

P-NUCLEO-LRWAN3

starter packs include the following firmware:

•

I-CUBE-LRWAN

LoRaWAN

STM32Cube Expansion Package for the microcontrollers in the STM32L0

Series, STM32L1 Series, STM32L4 Series, and Series

•

Binary for the STM32F746ZGT6 microcontroller of the LoRaWAN

gateway Nucleo board

3.1

I-CUBE-LRWAN LoRaWAN

STM32Cube Expansion Package

The

I-CUBE-LRWAN

Expansion Package consists of a set of libraries and application examples for STM32L0

Series, STM32L1 Series, STM32L4 Series, and Series microcontrollers acting as end-devices. This
firmware Expansion Package is downloadable from

www.st.com/en/product/i-cube-lrwan

A specific firmware project called

AT_Master

is an example code available only for the STM32L0 Series

microcontroller interfacing either with the

I-NUCLEO-LRWAN1

USI

LoRa

expansion board, or with the

LRWAN_NS1 RisingHF LoRa

expansion board. The

AT_Master

sample project implements a host

AT_Master

application that controls the LoRa

modem via AT commands, establishes a link with the LoRaWAN

network,

and sends sensor data.

STM32F7 Nucleo LoRaWAN

gateway firmware

Firmware is based on the Semtech packet forwarder protocol ported over to the STM32F746ZGT6 device. The
gateway parameters are fully reconfigurable by means of the AT command interface through the ST-LINK USB
Virtual COM port. Refer to

[3]

for details.
