Demod Method
The OOK demodulation methods, the options are: Peak
TH, or Fixed TH.
Peak TH

Fixed Demod TH
The threshold value when the Demod Method is “Fixed
TH”, the range is from 0 to 255. It is only available when
Demod Method is set to Fixed TH.

Peak Drop Rate
The RSSI peak drop rate, the options are: 1 step/4
symbols, 1 step/2 symbols, 1 step/1 symbols, or 1 step/0.5
symbols.
1 step/4 symbols

4.1 Demod Method
The OOK demodulation is done by comparing the RSSI to a demodulation threshold. The threshold is an 8-bit binary value that is
comparable to the 8-bit digitized RSSI.
4.1.1 Fixed Threshold Method
When the “Demod Method” is set to Fixed TH, once the RSSI goes above the threshold, logic 1 is output as the demodulated
signal, otherwise logic 0 is output. The demodulated signal is then sent to the decoder to perform packet decoding and data pins
controlling.
