Works try and catch on esp8266

[espruino-discuss]

Posted at 2018-04-10 by Frida

It seems to work on esp32
On esp32 I get a catch, but on esp8266 nothing happens

// mqtt_simple_V0.6_test01.js

var ver = 'V0.6';

var client;

function onConnect() {
  console.log('her er der noget');
}


function onInit(){
  var logon = require('LOGON');

  console.log("Connecting to WiFi");
  wifi = require("Wifi");
  wifi.connect(logon.ssid, {password:logon.pass}, function(err){
    console.log("connected? err=", err, "info=", wifi.getIP());

    console.log('creating client');

    try {
      client = require("net").connect({host: "192.168.20.21", port: 1883}, onConnect);
    } // end try

    catch(e) {
      console.log('err ' + e);
    } // end catch

  });
}


onInit(); // remove before save()

Yes, on esp32, I get the error because I have not started the client, but nothing on esp8266
