Easy way (non real-time)

Send and receive samples from files to simulator

$ villas pipe lab3.conf udp_node1 < file_send.dat > file_recv.dat

Note: In this lab all samples of file.dat will be sent immediately to udp_node1. Usually, this is not the desired behaviour. We will show later how to stream the samples in real-time to a destination node.

Better way (real-time)

 nodes = {
    file_node1 = {
            type = "file",
 
            uri = "file_send.dat"
            
            in = {
                    
            }
    }
 }

In order to stream the samples in real-time from a file, we will use the File node-type with the following configuration file (lab7.conf):

Stream samples in real-time from file

$ villas pipe lab7.conf file_node1 | villas pipe lab3.conf udp_node1 > file_recv.dat
