Skylo NTN: Signal Quality Check feature

[JordanYates]

The NTN AT command guide documents a "Signal quality check" option for performing a pre-check before attempting to re-attach to the Skylo network:

https://docs.nordicsemi.com/r/bundle/ref_at_commands_nrf91x1_ntn/page/ref/at_commands/ntn/skylo_set.html

I can't find any information on how this feature works elsewhere in the docs:

• When the check runs
• Whether it can be manually triggered by the application (without the attach step if it passes)
• How the application is notified on failure or success

Being able to manually trigger the check and receive a result in the application (ideally with signal strength information) would be extremely advantageous for quickly evaluating connection strength without having the send dozens of packets to calculate success rates. In a production environment, getting a notification on failure is important for handling pending data.

Alternatively, does `AT%XMONITOR` serve the purpose of application-level signal strength evalulation for NTN?

I guess the idea is, the check doesn't require that much energy but sending will require the energy,

In my experience that's not the case. The check already required a lot of energy. Therefore the idea doesn't pay off.
