And the firmware in the device matches the UHD you have? Based on my structure,
the firmware should be matching (since when I did the flow graph with the UDP,
everything went fine except for data loss) and correct me if I'm wrong, but an
error would come on saying that the firmware is not compatible?
Assuming that there's nothing *else* on the network connection between the host
computer and the USRP device, that's the only thing I can think
of that might cause it to be pingable, but UHD can't communicate with it,
unless you have firewall rules preventing communications at the
UHD layer...
I'll dig into it more to see what else I can come up with.
Thank You,
Marcus

Ping 192.168.10.2 is returning data
what does uhd_usrp_probe --args "addr=192.168.10.2"
Return?
This returns an error message:
RuntimeError: LookupError: KeyError: No devices found for -------->
Device Address:
Addr: (192.168.10.2)

Ok so now I went to try out my architecture this time with a TCP source and
sink. I have pictures included where the sending side is (TCPrecievestation)
and the receiving side is (TCPreceivedisplaystation).
On the (TCPreceievestation), the last three lines in the bottom window is as
follows:
RuntimeError: LookupError: KeyError: No devices found for -------->
Device Address:
Addr: (My USRP's IP address)
On the (TCPreceievedisplaystation), all I am getting is this:
using volk machine: avx_64_mmx_orc
To add, I have scopes for both the sending and receiving end, but as I run
them, the plots do not show.
Is there something that I could be missing since I am dealing with TCP and not
UDP?
One thing I noticed immediately is that you have the sample rate set to 32k,
which is not a valid sample rate for ANY USRP hardware.
On the machine that has the USRP connected (presumable this is a N2xx or
USRP2?), what does:
ping 192.168.10.2
return?
what does uhd_usrp_probe --args "addr=192.168.10.2"
Return?
