Hi All,

        Here is my experiment environment:
                Host A: one USRP1 + two RFX2400
                Host B: one USRP1 + one RFX2400
                Both of these two hosts, I am using the gnuradio trunk
version and fedora core 7.
        Goal: tunnel on a specific spectrum and sense a wideband spectrum
range(2.3GHz to 2.5GHz in this example).

        I want to use this environment to achieve tunneling between two
hosts and simultaneously sense wideband on host A, so I have modified the
widespectrum.py and tunnel.py. I have tried to combine these two programs
into one program. However when I execute this program (type
./tunnel_sense.py –f 2.462G 2.3G 2.5G), this program locked after I
configure the gr0 interface.

        I know that when I configure the gr0 interface, the procedure will
jump into the sense_loop(tb), but I can’t realize why the procedure locked
at the while loop of sense_loop(tb). The attached file is the program which
I have modified.

        Is there anyone doing the thing or any suggestion? Any suggestions
are good for me…more appreciated, thanks.

Joey
