[Discuss-gnuradio] USRP's not Communicating

Hello,

I want to transmit the data between two USRP's and make them communicate
with each other. But I guess the packets are not being received
properly.
I am connected the two USRP's to the same laptop and trying it. Is that
applicable? I mean, will it work if I do that? Or should I connect to
two computers and perform that? I have been receiving this error.

linux; GNU C++ version 4.8.4; Boost_105500;
UHD_003.009.git-144-g407e3086

Using Volk machine: avx_64_mmx
-- Opening a USRP1 device...
-- Using FPGA clock rate of 64.000000MHz...

No gain specified.
Setting gain to 56.250000 (from [0.000000, 112.500000])

Please suggest. Thank you
