BTW, what does that guy mean "Not sure when you updated, but we have changed
the checked in code to default to 2437, and run it like this (as a NetBSD
rc.d start script)", following the above link?
details if you care, but surely they have little to do with your issues.
http://www.netbsd.org/docs/guide/en/chap-rc.html
about your output:
./bbn_80211b_rx.py -f 2.437G -v -b
Bits Per Encoded Sample = 8
adc frequency = 64000000
decimation frequency = 16
input_rate = 4000000
gain = 45.0
desired freq = 2437000000.0
baseband frequency 2432000000.0
dxc frequency -5000000.0
Samples per data bit = 8
>>> gr_fir_ccf: using SSE
2.432G is used instead of 2.437G. Also the dxc frequency is negative. And
no packets get printed out.
I am unclear on dxc.
Are you sure there are strong signals at the 1 Mb/s rate on 2437 MHz?
/adroitgrdevel/gr-bbn/src/examples/bbn_80211b_rx.py just like this:
What operating system are you running on? That script may be expecting
the NetBSD tap device, and your system's might be different.
