Hello @JoaoFoonseca and welcome to the ST Community :smiling_face_with_smiling_eyes:.

I suggest you to refer to the Sub-Ghz Phy examples on the I-CUBE-LRWAN. I should be helpful to understand how it should work. For me, i suggest you to use our STM32 long range product the STM32WL that is an MCU with Sub-Ghz communication features. You can find on YouTube lot of videos that help you working with this product. Even a full STM32CubeWL library for this product. For more details refer to this link.

Best Regards.

    What do you mean by that?

    Connecting the boards is easy - the  I-NUCLEO-LRWAN1 just plugs into the Adruino sockets of the Nucleo-F411RE.

    Note that the  I-NUCLEO-LRWAN1 is now classed as Obsolete.

    EDIT:

    The catch here is that the UART TX & RX on the Arduino D1 & D0 pins is needed for the communication between the Nucleo processor and the USI module on the shield.

    Therefore SB13 & SB14 will need to be removed - and this means that you won't have any comms over the ST-Link's Virtual COM Port (VCP).

    As @STTwo-32 said, you may be better off with an STM32WL board - or, perhaps the B-L072Z-LRWAN1...

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
