Hello!

I am having trouble trying to create a continuous stream of complex shorts from 
multiple (2) X310 USRPs (each running 2 channels) over a single 1gigE switch 
(at a very low sampling rate); currently it appears as though I can only stream 
from one USRP at a time and I can't seem to figure out why. I should note I 
don't have this problem running each USRP on its own dedicated network (but 
unfortunately that won't be possible moving forward).

To date, I have been using the rx_multi_samples example provided with UHD 
(source 003.007.002). I don’t seem to have any issue connecting to both USRPs 
and setting the parameters via the args=”addr0=192.168.10.2, 
addr1=192.168.10.3” command. It is just that when I call rx_stream->recv only 
the lights on the USRP which was listed first in args turn on. The subdev spec 
and channel selection for each USRP is set to "A:A B:A" and "0,1" and the 
incoming data from rx_stream is two channels of complex shorts (not 4 like I 
would expect from 2 USRPs).

Do I have to initiate the streams differently or am I missing something?

Thanks!

-Andrew
