Full duplex problem in usrp N200

GNU Radio
1

Hello,

I am currently working on DSA in mesh network for this purpose I have
been using
Gnuradio and USRP for practical implementation.

Previously I was using USRP1 with RFX2400 board for that the full duplex
mode was working fine (.i.e. Transmit and receive simultaneously).

However last week we purchased new USRP N200 with SBX daughterbard for
our project but I am unable to perform full duplex operation on it. I
can either transmit or receive at a time. When I try to perform transmit
and receive operation together (starting receive first then transmit
later or vice versa) I get an error “that device not found at the
specified address:192.168.10.2”.

I have installed the latest firmware and image as well as the
gnuradio+uhd version.

can anyone help me to sort out this problem ?

Tahir

I assume you are trying to open the same device in multiple processes?
In this case, it is working perfectly. The rule is 1 process per device.
