LoRaMac-node -> Lora Basics Modem (SWL2001)

[wietsedv]

Zephyr uses the LoRaMac-node LoRaWAN implementation. According to the note at the top of the README, Semtech seems to have rewritten their reference implementation and released this new version as LoRa Basics Modem:

Subsequent to the availability of a new and feature enhanced LoRaWAN® stack within LoRa Basics™ Modem, Semtech has decided to transition LoRaMac-Node to maintenance mode (critical bug fixes will still be supported).

LoRa Basics™ Modem is the platform implementing new LoRaWAN features (i.e. Relay, CSMA) and will support future improvements introduced by the LoRa Alliance (e.g. LoRaWAN 1.2).
While the formerly introduced LoRaMac-Node stack transitions to maintenance mode Semtech recommends customers to use LoRa Basics™ Modem for new designs.

Moreover, Semtech has already released an out of tree Zephyr driver. I have not tested this myself nor have I inspected the code to check how mature this implementation seems.

Are there active plans of migrating to Lora Basics Modem?

There is an open PR for integrating LBM in #77495.
I was not aware of the OOT Zephyr driver, I'm not sure why Semtech haven't tried to upstream that themselves.

Thanks for pointing this out! It did not seem to show up when I searched for it.
