For Marcus, I have a more general question regarding the flow graph. If I have in my GRC both a UHD sink and a UHD source block, is it true that the USRP2 will stay in receive mode until there're samples on the transmit buffer? Will it then switch to transmit mode and transmit until the transmit buffer is empty and switch back to receive mode?
Thanks,
Johnny

Dear GNU Radio list's members,
I have a set of USRP2+XCVR2450 with the host computers configured with
the *GNU Radio classic drivers* (v.3.3.0).
My main idea is to transmit and receive data through a wireless
connection between the USRP2s. For now, I'm unaware of the PHY
technology but the only restriction I have is that the transmission and
reception of each node has to be carried out in a single USRP2.
GNU Radio by default provides a set of examples but, as far as I know,
*tunnel.py* (in gnuradio-examples/digital folder) is the only script
that meets such condition.
I would like to ask whether you know the existence any other
implementation that executes both the transmission and reception
procedure in the same USRP2s.
Thank you in advance for your time. Any hint would be appreciated.
Regards,
J.R.

You should be aware that the XCVR2450 is a *half duplex* daughtercard--the hardware is physically incapable of receiving and
transmitting *at the same time*, although it's perfectly capable of half-duplex operations, which can certainly happen on a single
USRP2 with suitable Gnu Radio flow-graph behind it.
