LoRaWAN software expansion for STM32Cube (UM2073)

LoRa® is a long range wireless area network allowing low-power sensors to report over ranges of up to a dozen kilometers.

The I-CUBE-LRWAN Expansion Package consists of a set of libraries and application examples for STM32L0, STM32L1 and STM32L4 Series microcontrollers acting as end-devices.

This package supports the SX1276MB1MAS, SX1276MB1LAS, SX1272MB2DAS, and the new radio generation sx126x mounted on SX1262DVK1DAS, SX1262DVK1CAS and SX1262DVK1BAS LoRa® radio expansion boards, provided by SEMTECH.

This package includes an application running on NUCLEO-L053R8, NUCLEO-L152RE, NUCLEO-L476RG and B-L072Z-LRWAN1 Discovery kits embedding the CMWX1ZZABZ-091 LoRa® module from Murata. It also supports a USI® LoRaWAN™ technology module through the I-NUCLEO-LRWAN1 expansion board and the RiSiNGHF® modem RHF0M003 mounted on LRWAN-NS1 expansion board available in P-NUCLEO-LRWAN3 (coming soon). The application reads sensor data from the X-NUCLEO-IKS01A2 expansion board and sends the sensor data to the LoRa® network in class A. For further details about the components of the LoRa® middleware library, refer to the STM32 LoRa® software expansion for STM32Cube User manual (UM2073).
