SDR code
hardware requirements
- needs a gnuradio-supported SDR with 2.4MS/s samplerate
- needs a tuner with support for the DECT frequency range
- rtlsdr with E4000 tuner works
- rtlsdr with more popular R820T tuner does not work (can't tune to DECT frequency range)
- tested with bladeRF and rtlsdr w/ E4000 tuner
- should work with hackRF as well
software requirements
- needs GNUradio
- needs a dummy0 network device
usage
- make
- create dummy0 interface: sudo modprobe dummy or sudo ip link add dummy0 type dummy
- start the dummy0 interface: sudo ifconfig dummy0 up
- run dectrcv as root: sudo ./dectrcv
- start the SDR part:
- If you use gnuradio version <= 3.7 : ./dectrx_37.py
- If you use gnuradio version >= 3.8 : ./dectrx_38.py
- set channel, gain values and ppm
- enjoy the DECT packets in wireshark
multichannel
If you want to use the multichannel feature you have to adjust the number of channels in the dectrcv.c.
