Zephyr (or other RTOS) and nRF9151 and Skylo certification

[Aclassifier]

When dealing with low power access via NTN (via Skylo), is there any limitation about any particular use of SW?

Like, is Zephyr or other RTOS combinable with the Skylo certified nRF9151?

The reason I ask is for curiosity and learning about the relationship between possible busy polling (?) in an RTOS vs. low energy requirements.

To extend the question: any RTOS vs. power requirements. Is there any general newbie question I should have asked?

In my experience from last year with NTN (not the nRF9151), it's easy, just multiply everything with at least 10:

- 10x more power consumption compared to NB-IoT

- 10x longer RTT (and you need to throttle the responses as well, though last year it was only 1 message with 200 bytes every 30s allowed).

- 10x times the costs

Maybe that has changed, we will see, how that develops.

I guess the main pattern will be something as "1 alive message per weak and notifications for important events on demand".
