Re: [Discuss-gnuradio] [Douglas Geiger BBN 802.11b] Porting code on USRP2 problems

[Ben Yahmed]

Good News!!!!
I finally succeeded to receive with an USRP2 packets sent with another 
USRP2. I tryed to modify the parameters and found the magic combination:


./bbn_80211b_tx.py -f 2.4G -e eth1  -i 24 -r 20
>>> gr_fir_ccf: using SSE

Network interface:  eth1
USRP2 address:  00:50:c2:85:30:cb
Using TX d'board id 0x0060
Tx baseband frequency:  2.4G
Tx DUC frequency:  0
Tx residual frequency:  0
Tx interpolation rate:  24
Samples per data bit:  8
