pico + WIZ550io + mqtt connection issue

I figured this out. setIP() returns true when it successfully finishes.

Updated onInit code:

function onInit() {
  console.log("Connecting to Ethernet");

  SPI2.setup({ mosi:B15, miso:B14, sck:B13 });
  eth = require("WIZnet").connect(SPI2, B10);

  console.log("Connect?: " + isConnected);

  isConnected = eth.setIP();
  console.log("Connect?: " + isConnected);

  if (isConnected == true) {
    mqttConnect();
  }

  //eth.getIP();
  eth.getIP(function(f,ip) {
    console.log("IP: ",ip);
    mqttConnect();
  });

}
