Hi, I want to develop my LoRaWan end node in STM32 L476RG, Is there any way to port or convert the STM32 WL series library to STM32 L476RG nucleo board library ?

The ST-CUBE libraries support L476RG

Hi, Thank you for the help. I have my STM32L476RG Nucleo board and RFM95 LoRa module only, which I have to interface with my Nucleo board via SPI. Is this library still works for this ? I dont have any extension boards

RFM95 appears to work like the SX1276

Why? What dictates the choice of the Nucleo board and the rather ancient RFM95 module?

Rather than struggle with less optimal hardware, can you use a Semtech SX126X board - this will allow you to run the soon to be deprecated LoRaMac-node and it’s replacement, LoRa Basic Modem.

Or even do you have to use the Nucleo - there are many other boards around running a variety of LW stacks.
