Hi,
My understanding is that remote streaming is available in UHD>=4.3 via:
https://files.ettus.com/manual/page_stream.html#stream_remote
However, I can not get it working using the example python scripts
provided, and also programmatically via C++.
I am using USRP-2974 with UHD host @ 192.168.30.1, USRP @
192.168.30.2, and I created a secondary ethernet interface (linux)
with address 192.168.30.30 on the same interface (network) as UHD host.
Ultimately I want to do this with C++, but I tried it with the example
“remote_rx.py” to rule out problems with my code.
Can you help me figure out why this doesn’t work?
Thanks,
—Cy
Can you confirm IP connectivity between the desired alternative
destination and the USRP (via ping, for example)??
Do you actually have something listening on port 54321? Do your
firewall rules block it?
