• I use a module WIZnet W5500 for network.
    My code:

    let WIZnet = require("WIZnet");
    var http = require("http");
    SPI2.setup({mosi: B15, miso: B14, sck: B13});
    let eth = WIZnet.connect(SPI2, B12);
    setTimeout(function() {
      console.log("ip", eth.getIP());

    If I unplug the net cable, this code stopped in 'ERROR: No free sockets found', but I don't know how to catch this error.

    On the other hand, how do I continuedly listen the eth while I plug the net cable for initializing the network?
