Hello USRP-users,
I have a fully updated N310 running UHD_3.13.0.0-release on the N310 and
the host laptop. The FPGA image has been updated as well to the latest XG.
I also have GNUradio 3.7.11 installed. The host can ping the N310 on the
SFP+0 port (192.168.10.2) successfully and the N310 can ping the host
(192.168.10.1) successfully as well.
I have a simple flow-graph that sends a sine into antenna 0 and a zero into
antennas 1-3. GNUradio fails to find the N310 when address is left blank or
if I put in the ip adress. Here is the output for leaving it blank.

Any help is greatly appreciated!
