3.2.4 - Activation of the Wavenis RF Asic RSSI threshold autocorrection
The RSSI threshold autocorrection is a functionality which allows WaveCard to adjust its threshold of
reception, according to the ambient noise in a preoccupation with an energy saving.
This functionality is adapted if WaveCard is fed by battery. at RESET of WaveCard, the RSSI threshold
autocorrection takes its state by default (i.e, activated).
