Hi all,
I would like to run the simple_mac.py on two machines with USRP1. Has
anyone
been successful in this issue? I downloaded the BBN codes from
https://www.cgran.org/wiki/BBN80211. I think that the simple_mac.py in
the
trunk does not work with 802.11PHY, so I tried to modify the
simple_mac.py
based on Ben’s codes (80211_mac.tar.gz (79K) from nabble.com).
However,
the ping function is still not working (From 10.10.10.1 icmp_seq=2
Destination Host Unreachable). I also tried to adjust the parameters. If
anyone has any suggestions whatsoever I would really appreciate it. I
attached the folder of my codes and post the terminal outputs as
following:
[root@localhost examples]# ./simple_mac.py -f 2400e6 -d 8
fusb_block_size = 1024
fusb_nblocks = 16
Using TX d’board A: Flex 2400 Tx MIMO B
gr_fir_ccf: using SSE
spb: 8
interp: 24
Carrier sense threshold: 50 dB
Allocated virtual ethernet interface: gr0
You must now use ifconfig to set its IP address. E.g.,
$ sudo ifconfig gr0 10.10.10.1
Be sure to use a different address in the same subnet for each machine.
