If I use the UHD driver directly (i.e. not using gnuradio framework) should I call "mimo_usrp::make" with argument "addr=192.168.10.11 192.168.20.11 192.168.30.11 192.168.40.11, addr=192.168.10.11 192.168.20.11 192.168.30.11 192.168.40.11" to achieve the same or how should the string be formatted ?

I have a few points to raise here regarding this release and block: 1- I am using a PC with four Ethernet ports. I burned the firmware and the fpga images created on 6-7-2010. Also, I tried assigning IP addresses from the same subnetwork: 192.168.10.X/24. However, Only a single USRP2 is discovered at a time while others are unreachable. (USRP2s IPs are also from the same subnetwork above) 2- Then I tried assigning IPs from 4 different subnetworks to the USRP2's, and all them can be discovered normally. Is it possible that they work using IPs from the same subnetwork or not? (case 1) 3- I used a MIMO source with 4 outputs and the following settings: freq: 2414000000, 2414000000, 2414000000, 2414000000 Arg: addr=192.168.10.11 192.168.20.11 192.168.30.11 192.168.40.11, recv_buff_size=50e6 50e6 50e6 50e6 sample rate: 195.312K ( Firstly, I used 32K but at runtime I was prompted to use this value) Gain= 35,35,35,35 Antennas= [‘RX2’, ‘RX2’, ‘RX2’, ‘RX2’] I connected the 4 outputs to graphic scopes but once I run the flowgraph, I see this error messages: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> >' what(): bad lexical cast: source type value could not be interpreted as target. I have Boost 1.38.0 installed and I did use this command for configuration: ./configure --with-boost=$BOOST_PREFIX Any advice or help regarding this issue, please?
