When two Steval-FKI433V2 evaluation boards yet maintain connection, the S2LPRadioGetRssidBm() functions for both boards show about -103dBm...-104dBm.
I can't get less RSSI level.
Has the least possible RSSI the same value as the receiver sensitivity for the Steval-FKI433V2?
If yes, why declared receiver sensitivity (up to -130 dBm) is not achievable?

Hi bvn123,
It is simply because what you measured was not the receiver sensitivity.
The receiver sensitivity is the minimum power level of the signal at the receiver input,
produced by a carrier at the nominal frequency of the receiver,
modulated with the normal test signal modulation,
which produces 1% BER after demodulation without correction.
It will be better to measure conductive mode, with proper RF settings.
