I want to access multiple USRPs from a host for MIMO. Currently, I need change IP address of host (subnet) to be able to access each USRP.

• Configuration for USRP2 device 0:
  • Ethernet interface IPv4 address: 192.168.10.1
  • Ethernet interface subnet mask: 255.255.255.0
  • USRP2 device IPv4 address: 192.168.10.2
• Configuration for USRP2 device 1:
  • Ethernet interface IPv4 address: 192.168.20.1
  • Ethernet interface subnet mask: 255.255.255.0
  • USRP2 device IPv4 address: 192.168.20.2

Is it possible to access multiple USRP without changing host IP?  Say, if I change some of the FPGA code or UHD. Throughput is not that important. Is there any guideline for developing such FPGA code?

Thanks,

You can change the IP address of the USRP2 to be on the same subnet as its buddies.
