Thanks Ethem for your quick response. This time we installed Matlab R2012b
and used targetinstaller to install USRP extensions. But the problem
of multiple
IP addresses still isn't solved. That is,
>> findsdru
linux; GNU C++ version 4.4.6; Boost_104400; UHD_003.002.003-vendor
---------- see libuhd version information above this line ----------
ans =
192.168.10.201,192.168.10.202,192.168.10.201,192.168.10.202
In addition to this problem, we also cannot change the IP addresses of the
devices. That is, SDRu by default uses 192.168.10.2, but our devices are
set to 192.168.10.{201,202}. And h =
comm.SDRuTransmitter('192.168.10.201')did not work:
>> h = comm.SDRuTransmitter('192.168.10.2')
Error using StringSet.checkValues (line 119)
Strings must be case-insensitive unique.

Hi Volkan,
I am sorry but it seems like this problem is actually resolved in 13a. If you
have a current license, you should be able to get the prerelease for 13a from
the MathWorks website.
One possible work around is to assign different subnets to each USRP. For
example, you can try to assign 192.168.10.2 and 192.168.20.2. I am not sure if
this is possible with a switch, but you can do it with two Ethernet cards.
Another alternative is to contact MathWorks support ([email protected])
directly and see if they can provide another workaround.
Regards,
Ethem

Hi!
In the result of "findsdru" command, we observe multiple (two) IP addresses for
each device. Consider the below network.

Here USRP2 devices are installed usrp2_fw.bin and usrp2_fpga.bin bundled with

Hello Ethem,
With R2013a, will targetinstaller suffice for the proper installation? Will
we need any additional source code, binary, etc.
installations/compilations/configurations?
Best.

targetinstaller should download and install all required software. You can also
use the "Add-Ons" popup on the MATLAB desktop and select "Get Hardware Support
Packages", which will show you all available support packages, including USRP.

Hello Ethem,
With R2013a, will targetinstaller suffice for the proper installation? Will we
need any additional source code, binary, etc.
installations/compilations/configurations?
Best.

Hi Volkan,
I am sorry but it seems like this problem is actually resolved in 13a. If you
have a current license, you should be able to get the prerelease for 13a from
the MathWorks website.
One possible work around is to assign different subnets to each USRP. For
example, you can try to assign 192.168.10.2 and 192.168.20.2. I am not sure if
this is possible with a switch, but you can do it with two Ethernet cards.
Another alternative is to contact MathWorks support
([email protected]<mailto:[email protected]>) directly and see if they
can provide another workaround.

Subject: Re: [USRP-users] Multiple IP Addresses Break MATLAB SDRU Package
Thanks Ethem for your quick response. This time we installed Matlab R2012b and
used targetinstaller to install USRP extensions. But the problem of multiple IP
addresses still isn't solved. That is,
>> findsdru
linux; GNU C++ version 4.4.6; Boost_104400; UHD_003.002.003-vendor
---------- see libuhd version information above this line ----------
ans =
192.168.10.201,192.168.10.202,192.168.10.201,192.168.10.202
In addition to this problem, we also cannot change the IP addresses of the
devices. That is, SDRu by default uses 192.168.10.2, but our devices are set to
192.168.10.{201,202}. And h = comm.SDRuTransmitter('192.168.10.201') did not
work:
>> h = comm.SDRuTransmitter('192.168.10.2')

We are totally stuck in this USRP+MATLAB jam, any helps will be really
appreciated!

Hi Volkan,
This problem is fixed in 12a. Also, please make sure that the UHD version on
the radio matches the MATLAB required UHD version.

Subject: [USRP-users] Multiple IP Addresses Break MATLAB SDRU Package
Hi!
In the result of "findsdru" command, we observe multiple (two) IP addresses for
each device. Consider the below network.
H1 [eth0]

|10.100.92.17/24<http://10.100.92.17/24>
|192.168.10.17/24<http://192.168.10.17/24>

Switch +---------- 192.168.10.202 -- USRP2

|192.168.10.18/24<http://192.168.10.18/24>
|
H2 [eth0]
Here USRP2 devices are installed usrp2_fw.bin and usrp2_fpga.bin bundled with
uhd-images_003.005.000-release.zip archive. H1 and H2 run MATLAB R2011b with
USRP(r) Hardware Binary Release
003.002.003<http://files.ettus.com/binaries/uhd_stable/releases/uhd_003.002.003-release/images-only/>
installed. When I type findsdru at the MATLAB command prompt it tells me that
>> findsdru

ans =
192.168.10.202,192.168.10.201,192.168.10.201,192.168.10.202
Per see, it observes multiple IP addresses from each device. Further, when I
try to run a simple demo bundled with the SDRU package it fails as follows.

Subject: [USRP-users] two LOs in USRP N210 with SBX when doing full
duplex
Message-ID:
<cakro2l2qejhfcctcbsk7sysemyfg4nc1zos4-wdp7orcgzd...@mail.gmail.com>
Content-Type: text/plain; charset=ISO-8859-1
Hi, All,
Based on what I know, SBX has two LOs for full duplex and they both
use the mother board's clock as reference. Is that right? So I am
wondering whether the phases of these two LOs are the same. If they
are not the same phase, will the offset be a constant? In my
experiments, I found that the phase randomly changes when i was doing
full duplex. Any thoughts? Thanks.
Best,
Gang

Two
independent frac-N synthesizers. They're be coherent with respect to
each other, but there'll be an unpredictable phase offset between them
every time they're tuned.
