Description

OOK_Thresh

7-0

r/w

OOK fixed threshold or min threshold in peak mode. By default at 6dB.

(d): “00000100” assuming 0.5dB RSSI step.

RSSI_val

7-0

RSSI output, 0.5 dB / bit

Note: READ-ONLY (not to be written)

OOK_thresh_step

7-5

r/w

Size of each decrement of the RSSI threshold in the OOK demodulator

000 => 0.5 dB (d)

100 => 3.0 dB

001 => 1.0 dB

101 => 4.0 dB

010 => 1.5 dB

110 => 5.0 dB

011 => 2.0 dB

111 => 6.0 dB

OOK_thresh_dec

_period

4-2

r/w

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

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

OOK_avg_thresh

_cutoff

1-0

r/w

Cutoff frequency of the averaging for the average mode of the OOK

threshold in demodulator

00 => fC ≈ BR / 8.π (d)

01 => Reserved

10 => Reserved

11 => fC ≈ BR / 32.π
