Hi Ruth,

In some cases, findsdru may return an IP address but you may not be able to establish a data connection due to a mismatch between the firmware version and the host UHD version.  Please make sure that you have the following firmware versions on your USRP device:

R2011a -- 003.000.001 
R2011b -- 003.002.003

You can contact MathWorks support for USRP and MATLAB/Simulink problems:  http://www.mathworks.com/support/

i've started attempting to utilize the USRP and MATLAB support for UHD. Error reported by S-function 'usrp_uhd_sfunrx' in 'sdruFMStereo/SDRu Receiver/usrp_uhd_sfunrx': Could not execute UHD driver command in 'createDriver_c': Could not create a UHD driver using IP addr ''. Attach a device at the specified address, correct the specified address to match an already attached device, or continue to work in off-line mode.

P.S. I have run 'findsdru' and it says the device is connected at IP address  I attempted to trace the code for where the error is being thrown and it appears to be related to where the 'findsdru' is being called in the code itself, which doesn't make a lot of sense to me.  Thanks in advance, Ruth
