Subject: | [Discuss-gnuradio] One USRP to do two different works |
Date: | Fri, 8 May 2009 03:05:40 +0800 |
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.
