RW Description
r/w
OOK fixed threshold or min threshold in peak mode. By default at 6dB.
(d): “00000100” assuming 0.5dB RSSI step.
r
RSSI output, 0.5 dB / bit
Note: READ-ONLY (not to be written)
Size of each decrement of the RSSI threshold in the OOK demodulator
000 => 0.5 dB (d) 100 => 3.0 dB
r/w 001 => 1.0 dB
010 => 1.5 dB
101 => 4.0 dB
110 => 5.0 dB
011 => 2.0 dB
111 => 6.0 dB
Period of decrement of the RSSI threshold in the OOK demodulator:
000 => once in each chip period (d)
001 => once in 2 chip periods
010 => once in 4 chip periods
r/w 011 => once in 8 chip periods
100 => twice in each chip period
101 => 4 times in each chip period
110 => 8 times in each chip period
111 => 16 times in each chip period
Cutoff frequency of the averaging for the average mode of the OOK
threshold in demodulator
r/w
00 => fC ≈ BR / 8.π (d)
01 => Reserved
10 => Reserved
11 => fC ≈ BR / 32.π
