Hi,
I want to use one USRP to do two different works on the two sides, which are A side tunneling with another USRP and B side sensing the channel condition. In my comprehension, there are Tx and Rx including in tunneling and Rx in sensing. In addition to set up the subdev as subdev[0][0] for tunneling and subdev[1][0] for sensing, is there anything that I should pay attention? Such as setting up the multiplexers or anything else? I’m facing an embarrassing situation now, I always got an error message which as below: usrp_open_interface:usb_claim_interface: failed interface 2 could not claim interface 2: Device or resource busy usrp_basic_rx: can't open rx interface RuntimeError: can’t open usrp1 I guess it seems the USRP gets stuck on the fusb_nblcok and fusb_block_size. I’m using 2.6.23 fc7 and my gnuradio version is trunk-version:10793. Is there anyone doing the same work or any good suggestion? Thanks, Joey.
