Currently I am testing a modified version of tunnel.py, but I am seeing
strange results. My modifications were essentially a re-factoring to
for future additions, however somehow I was able to receive a
packet on the same USRP that transmitted it.
The USRP transmit/receive paths are set-up exactly the same as in the
original tunnel.py, the only difference is that I abstracted the tun/tap
layer a bit (in order to improve the MAC layer functionality). I did not
change the cs_mac loop and I am only using a single USRP with the
tunnel to flood PING requests. I am using only a single antenna on a WBX
I know that I am receiving a transmitted packet because in
I am using scapy to dump the packet and inspect its contents. This
happen consistently - I am flooding out PING requests but only a
few are “looped back” (for lack of a better word).
Now, can anyone explain how this could possibly happen?
