Gosh. Too bad they want for a copy of the standard. Bleerg.
As long as you don't mind using a draft version of
Current rx socket buffer size: 42080
Adjust max rx socket buffer size (linux only):
sysctl -w net.core.rmem_max=VALUE
Using: XCVR2450 RX (0x0061)
Using: XCVR2450 TX (0x0060)
I tried some different values in
set_recv_buff_size(size_t(xxx)); //some big number!,
3.7e6 still works as the "big"

I would really like to use the USRP2 with my MacBook. My first test with the

The rx and tx data packets are samples encapsulated in vrt headers for
IF data: http://www.digitalif.org/
The control protocol is just a bunch of enums and structs in a header
shared by firmware and host:

I can confirm that after a couple of bits of finger-trouble on my part,
I built both UHD, and GR-UHD, and
was able to install 'em both. I don't have a USRP2 to do tests, but at
least the build went well.
If there's a succinct protocol description out there for UHD-over-UDP
I'd start work on a W
When no address is specified, the find devices will send a broadcast udp
packet to each interface. I experienced identical behavior on a fedora
11 box because the firewall was interfering with broadcast packets.
After turning off the firewall with system-config-firewall, the find
devices worked

That seems odd, it shouldnt be able to make a device without finding it
first. That is if nothing comes up for ::find, then the ::make will yell
at you.
Is this problem repeatable, if you repeatedly call uhd_find_devices,
will it continue to come up blank?

To follow up: it appears th
That does look a bit suspicious. I have two suggestions:
1) if its a firewall issue, make sure that the linux firewall is off
2) if its a timeout issue edit the udp_simple.cpp and change
milliseconds(100) to something larger, say 1000

XCVR2450 and RFX series boards are now supported in the UHD.
Here is the link to the wiki and manual that I have been working on:

The microblaze firmware has changed since the previous announcement.
