IoT protocol Z-Wave transmits on
- set: 9.6Kbps | FSK | Manchester coding
- set: 40Kbps | FSK | NRZ coding
- set 100Kbps | GFSK | NRZ coding
I’ve used scapy-radio for receiving Z-Wave frames. They have implemented blocks for 2. set(40Kbps|FSK|NRZ) and I’m trying to configure blocks for 1. set (9.6Kbps|FSK|Manchester). However, I am not able to receive frames like for 2. set and I would like to ask what could be wrong.
Here are my current blocks for 1. set:
and here is output from ClockRecovery M&M:
Here are blocks from scapy-radio(40Kbps|FSK|NRZ) which works:
I don’t uderstand many things and some values are “random” or default:
Taps of Frequency Xlating FIR Filter:
Low Pass filter
and Clock Recovery M&M block.
Block Z-Wave PacketSink 9.6 is Manchester decoder and should work properly.
is here anybody, who can help me? I will appreciate any help.
