Hi,
I have already tried to use USRP2 as transmitter and USRP1 as receiver using
transmit_path_usrp2 file for usrp2. However I am not able to figure out the
bit rate, interpolation and decimation rate to be set for successful
communication. I am not able to catch the packets using USRP1. Were
Hi,
I don't have USRP but just USRP2.
I think you should try this part of code :
svn co https://www.cgran.org/cgran/projects/bbn_80211/branches/usrp2_version
there are the bbn_80211b_rx.py bbn_80211b_tx.py files wich work fine for
many of us between 2 USRP2. I used these options:
Hi,
I replaced your USRP2'mac adress with mine and tryed the code but no
received packet even with USRP2. I suggest that you use the usrp2_version
branch code to transmit packets with USRP2 and try to catch them with
USRP1 since this code works fine for many of us.

Hi,
I don't have two usprp2. So I am trying to communicate between usrp1 and
usrp2. Moreover, in the transmit_path.py file I have hard coded my usrp2's
mac address so you would have to replace it with yours before using it. If
there are any other problems with the code then please let me know
Hi,
Did you try to send and receive packets between 2 USRP2? I tryed but
without any result. Are you sure that it's working correctly? I will
have a look to the code in more details and tell you if something will
work.

Hi,
I tried 100e6 as converter rates for USRP2. But it is still not working.
USRP1 and USRP2 receive and transmit at 500kbps which is the default bit
rate defined in pick_bitrate. So how could they have bit rate
incompatibility. The samples per symbol is also 2 for both of them. I am
still
The DAC rate is 100e6. The bitrate is the desired data rate of the
over the air modulation. It should be MUCH less, like 100k to 1M or so.
There is absolutely nothing in any of the systems for which 200e6 is a
correct choice.

This is what I get when I run benchmark _tx.py and benchmark_rx.py
