Introduction
This user manual describes the
STM32L1 Series, and STM32L4 Series microcontrollers. This document also explains how to interface with the LoRaWAN
®
manage the LoRa
wireless link.
®
LoRa
is a type of wireless telecommunication network designed to allow long-range communications at a very low bit-rate
and enabling long-life battery-operated sensors. LoRaWAN
interoperability with the LoRa
®
protocol named LoRaWAN
.
The I-CUBE-LRWAN main features are the following:
•
Integration-ready application
•
Easy add-on of the low-power LoRa
•
Extremely-low CPU load
•
No latency requirements
•
Small STM32 memory footprint
•
Low-power timing services provided
The I-CUBE-LRWAN Expansion Package is based on the STM32Cube HAL drivers (Refer to
This user manual provides customer examples on NUCLEO-L053R8, NUCLEO-L073RZ, NUCLEO-L152RE, and
L476RG
using Semtech expansion boards SX1276MB1MAS, SX1276MB1LAS, SX1272MB2DAS, SX1262DVK1DAS,
SX1262DVK1CAS, and SX1262DVK1BAS.
