[Discuss-gnuradio] modified simple_mac.py for USRP1

[Sheng-Hui Liao]

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:

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.
