[Discuss-gnuradio] Tunnel and sense in the same USRP device

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
