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).
The modification and reading commands of the autocorrection state, are as follows :
CMD NAME DESCRIPTION
0x46 REQ_WRITE_AUTOCORR_STATE Request to update WAVENIS RF ASIC RSSI Threshold autocorrection state
0x47 RES_WRITE_AUTOCORR_STATE Response from the radio board to the WAVENIS® RF ASIC autocorrection state update
0x5A REQ_READ_AUTOCORR_STATE Request to read WAVENIS RF ASIC RSSI Threshold autocorrection state
0x5B RES_READ_AUTOCORR_STATE Response from the radio board to the WAVENIS® RF ASIC autocorrection state read
Remark : In the command byte coding, the Response frame type are taking the Request command byte value with
the LSB bit set to 1.
