3.3.4 Activating RSSI threshold auto-correction
RSSI threshold auto-correction is a feature that enables Wavecard to adjust its reception threshold according
to ambient noise. This feature is consistent with other Wavenis power-saving techniques, and is implemented
by battery-powered Wavecard modules at reset. By default RSSI threshold auto-correction is activated.
Commands for modifying and reading the auto-correction state are:
CMD NAME DESCRIPTION
0x46 REQ_WRITE_AUTOCORR_STATE Request to update threshold auto-correction state
0x47 RES_WRITE_AUTOCORR_STATE
Radio board response threshold auto-correction state
update
0x5A REQ_READ_AUTOCORR_STATE Request to read threshold auto-correction state
0x5B RES_READ_AUTOCORR_STATE
Radio board response to threshold auto-correction state
read
Note: In command byte coding, response frames reuse the request command with the LSB bit set to 1.
