SBX is the daughterboard which supports full-duplex, but when I run the tunnel.py to do the Ping experiment over the OFDM communication link, I found that the transmitter can receive a lot of packets which are transmitted by itself. This causes failure for ARP query and the Ping requests. I see in the forum, many friends meet the failure of tunnel.py because they are using the XCVR2450 which is half-duplex. But why I still have this tunnel.py failed even when I am using the full-duplex SBX?
Should I use different frequencies for the TX and RX in the same USRP? Does the SBX support the TDD based full-duplex?
