  • I have an issue somewhat similar to user124799. I recently picked up a couple of MELIFE ESP32 boards because I'm having trouble obtaining Espruinio WIFI boards (so sorry Gordon!). I flashed 2v08 and ran this simple web server:

    var wifi;
    var count = 0;
    
    function getContent() {
      return '<html><h1>' + count++ + '</h1></html>';
    }
    
    function sendPage(res) {
      var content = getContent();
      res.writeHead(200, {'Content-Type': 'text/html', 'Content-Length':content.length});
      res.end(content);
    }
    
    function onPageRequest(req, res) {
      var a = url.parse(req.url, true);
      if (a.pathname=="/") {
          sendPage(res);
      }
    }
    
    function onConnected() {
      wifi.getIP(function(e,ip) {
        lip = ip.ip;
        require("http").createServer(onPageReque­st).listen(80);
      });
    }
    
    function onInit() {
      wifi = require("Wifi");
      setTimeout(onConnected, 2000);
    }
    

    I used a timeout because wifi.connect("***", { password : "***" }, onConnected) doesn't seem to call 'onConnected'. Anyhow, it runs okay for a minute or so then dies. The console shows this error:

    >E (5287) event: post event to user fail!
    E (8131) event: post event to user fail!
    WARNING: Wifi:startMDNS - espressif
    >E (34066) event: post event to user fail!
    E (36911) event: post event to user fail!
    

    The first 3 lines print on bootup - the last 2 lines print right when the ESP32 dies.

    Searching on the error led me to this page:
    https://github.com/espruino/Espruino/iss­ues/1571
    Which led me to try an older build - specifically this one:
    http://www.espruino.com/binaries/travis/­1a1fd36b740547ece5dda46220c9489bdbd17ff0­/espruino_esp32.bin

    Which looks like 2v00.42. The ESP32 works fine with this build.
    Is there a wifi issue with 2v08?
