If you execute the following commands you will get rid of those warnings.
These adjust the maximum read and write buffer sizes allowed that the OS is

Hi Anis,
I think a good starting would be to modify "rx_samples_to_file.cpp" or
"tx_samples_to_file.cpp.". The files are located in uhd/host/examples.
How many USRPs will you use? Will they use the same host machine? Time
synchronization is possible using the PPS input on a USRP2 or N2xx. My
Hi Julio,
You are simply not giving enough information for us to help you
effectively. Please include more details about your USRP2 setup
(daughterboard, host specifications, etc).
Regards,
Ryan

Use the firmware and FPGA image that corresponds to the distribution of UHD
that you have chosen to use. I don't think it's necessary to update
firmware unless you're getting runtime errors from UHD (it will explicitly
state that your firmware is not compatible with your version of UHD).

Excellent, much appreciated!

Hi again,
The "device streaming" documentation mentions that users may register their
own data types and converter routines. I'd like to implement a converter
that takes the sc8 data type from the wire and converts to an sc8 host data
type. It looks like Josh added this functionality in November

Hi all,
My research group is continuing our setup of two servers with multiple
N210s for a GNSS application. Each server will have 4 or 5 N210s recording
RF data at frequencies of interest. All are to be locked to the 10MHz
reference and 1 PPS output from a Septentrio PolaRxS. I have successful

Hi list,
We've setup 4 USRP N210 rev4s with a Dell PowerEdge R510 server to collect
RF data for GPS related experiments. The server works great and we seem to
be able to write 20 Msps from each device simultaneously to a RAID array
with no overflows. However, after each collection program is ter
