I stumbled across this while searching for pico lora basics modem. Not sure if you got this going but I have ported lora basics modem to pico/pico2. I've got it working with ping pong example and OTAA with my gateway (chirp stack). Haven't done anything with FOUTA. I had a bunch of Waveshare Lora Hats (pico and rpi) that I wanted to get going.

If anyone is interested you can check out:

Do you have any github repo for this code?

Ready for the actual "port to Pico API" work.

All sources needed to compile an example are now part of the build. And then I commented out anything in the code that's failing to compile (meaning: relying on STMicro HAL).

It's the approach I usually take while porting:

get all necessary files and functions in. Compile often to learn which include or .c files are missing.
stop when there's no errors left related to missing code.
Then replace each remaining compile error with a TODO comment (those are functions from the STMicro HAL that I'll need to port.
use the IDE's TODO extension to revisit all the TODOs and adapt them to the Pico C/C++ SDK API

I haven't counted yet, but it 'll be about 100 functions ...

Very interesting.

As I recall you can get some decent range over LoRaWan.
