Magnitude == RSSI?

I’ve noticed that some dboards have RSSI sensors while others don’t.
Since I’m using a SBX (rev 3) which doesn’t seem to have such a sensor,
I’m wondering if it’s also correct to use the magnitude of the samples
as an indicator for the RSS or is this value somehow “distorted”?

Cheers,
Matthias

You shouldn’t use the magnitude of the received samples as RSSI. The
magnitudes are generally in nondescript ‘engineering units (dB)’.

If you want to calculate RSSI, Marcus L. has posted a good solution a
few times in the past:
