Support for RP2040 sleep / dormant mode #1

Hi @CodeUnit10X

I'm very impressed by your work on this repository! In contrast so other SX1262 libraries, this one separates Semtech upstream code and your own code in a clean way and it relies on the Pico SDK - not some dirty Arduino glue code. :clap:

As I'm looking forward to testing your code on my RAK11310 LoRa module, I'd like to know: Have you ever tested RP2040's "sleep" or "dormant" power saving modes work with the current version of your code? In my current project I'm heavily relying on power saving.

If it's completely missing, I might be able to add it / make it work. My microcontroller expertise is quite limited, so I just wanted to know if you have gathered any experience in RP2040 power saving and LoRa yet :smiley:

Hi,

The short answer is no not yet. This has been my learn learn more about LoRa and Pico project so right now I've just got the basic port done and joining via OTAA and uplinks working.

I do plan on looking into it at some point, however if you want to look into it that would be great.

I was using sleep_ms, which is supposed todo a lower power sleep. I assumed you would sleep for the value returned by smtc_modem_run_engine, and using sleep_ms would put you in low power mode during that time.
