How to connect two E312 USRP to one host in simulink?

The tutorial seems not working? I tried to use two model, one for Tx the another for Rx, failed too, any idea?

The error is like this:

%%%%%%

An error occurred while running the simulation and the simulation was terminated

Caused by:

A runtime error occurred in the block 'testRx/E310 Receiver' during simulation.

A standard exception occurred during the execution of a driver function. The exception reported was:

Error in SDRSystemBase.p

Error in SDRRxZynqFMC234SL.p

%%%%%%%%

However, I can ping both of the USRPs. The ip address of the Tx is 192.168.3.2. The one for Rx is 192.168.3.4. The host ip is 192.168.3.1. The image is programmed using the add on setup.

Any idea?

You mentioned that host ip was 192.168.3.1, and that both radios are connected to the same subnet 192.168.3.x; can you confirm how you have connected the radios to your host?

The document link provided here details the requirement to have each radio connected to a different NIC, with different subnets.

Thank you so much. I should have read the documnent more carefully. The image used here is different from traditional zynq or raspberry or WARP. why we can not connect them to the same subnet? (..)|| But, still thank you.

I have the same problem how to get two E310s to connect to one host without conflict.

This is the documentation:

Setup for Two Radios Connecting to One Host

To develop a transmitter and a receiver on the same computer, you need two supported radio hardware. For a list of supported hardware, see Hardware Support. In addition, your host must have two dedicated Ethernet connections with different MAC addresses, one for each radio hardware. To have simultaneous Internet access in the absence of a wireless connection, the host computer must have three Ethernet connections.

Does it mean that my host must have two Ethernet connections with two MAC addresses.My computer has only one Ethernet card, so I can only connect to two devices sometimes, but this is extremely unstable
