I’ve got two machines with one usrp each using basic tx/rx board pairs.
As soon as I start tunnel.py on each and set the ip’s, one machine

If i disconnect wires, both sides go silent, reconnect and one or both
start showing BBBBBBBBBBBBBBBBb…
what is the ‘B’ anyway?
‘B’ means “backoff”.
It prints a B everytime it attempts to transmit if it detects carrier.
I cannot ping between the hosts… what am I missing?
First off, this example will only work with RFX-* daugherboards, not
the basic tx and rx board. Why: we currently can’t enable/disable the
transmitter on the basic tx board.
If using a RFX-* board and you see this, try setting the rx gain lower
and/or the carrier sense threshold higher.
$ tunnel --help
will give help
