I'm not sure of the frequency so I tried ./bbn_80211b_rx.py -f 2.462G -d 8 -b -v Bits Per Encoded Sample = 8 adc frequency = 64000000 decimation frequency = 8 input_rate = 8000000 gain = 45.0 desired freq = 2462000000.0 baseband frequency 2460000000.0 dxc frequency -2000000.0 Samples per data bit = 8 >>> gr_fir_ccf: using SSE PKT: len=77, rssi=-22, src=00:13:46:16:28:AA, time=557560, rate=1 Mbps PKT: len=77, rssi=-29, src=00:13:46:16:28:AA, time=1786312, rate=1 Mbps PKT: len=77, rssi=-26, src=00:13:46:16:28:AA, time=1991192, rate=1 Mbps PKT: len=77, rssi=-27, src=00:13:46:16:28:AA, time=2195928, rate=1 Mbps PKT: len=77, rssi=-19, src=00:13:46:16:28:AA, time=2912744, rate=1 Mbps PKT: len=77, rssi=-28, src=00:13:46:16:28:AA, time=3527168, rate=1 Mbps PKT: len=77, rssi=-25, src=00:13:46:16:28:AA, time=3936776, rate=1 Mbps PKT: len=77, rssi=-26, src=00:13:46:16:28:AA, time=4141640, rate=1 Mbps PKT: len=77, rssi=-24, src=00:13:46:16:28:AA, time=4858456, rate=1 Mbps PKT: len=77, rssi=-26, src=00:13:46:16:28:AA, time=5063192, rate=1 Mbps PKT: len=77, rssi=-21, src=00:13:46:16:28:AA, time=5268192, rate=1 Mbps
This time packets are received. It seems to me that (desired freq) + (dxc frequency) = (baseband frequency) BTW, I'm in Ubuntu 8.04 Greg Troxel wrote: > > 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.
