mqtt or createServer causing Uncaught CWMODE failed: Timeout

Thanks for the help. It does seem that the wifi.on('connected' event is only triggered once, and only on wifi.connect and not wifi.startAP (based on login inside the event handler).

Just from a design perspective, it does make sense to do certain things if and only if the wifi actually made a successful connection, so that's why I've stuck with keeping things inside the handler. Also, now with the into delays, everything has been working 100% of the time.

Here's what I finally settled on (relevant functions only):

function onInit() {

  SPI1.setup({mosi:A7, miso:A6, sck:A5});
  bme = require("BME280").connectSPI(SPI1, B1);

  setTimeout(startApAndStation, 2000);

  wifi.on('disconnected', () => {
    mqtt.disconnect();
    wifi.stopAP();
    clearInterval(timer);
  });

  wifi.on('connected', () => {
    setTimeout(() => { require("http").createServer(pageReq).listen(8080); }, 2000);
    setTimeout(() => { mqtt = require("MQTT").connect({host: "xxx.xxx.xxx.xxx"}); }, 4000);
    setTimeout (() => { dataInterval(); }, 8000);
  });
}

function startApAndStation() {
  wifi.startAP('AgilatechESP', { password: 'xxxxxxxx', authMode: 'wpa2' }, (err) => {
    if (err) throw err;
    else wifi.setAPIP({ip:"10.0.132.1", gw:"10.0.132.1", netmask:"255.255.255.0"}, (err) => {
      if (err) throw err;
      else wifi.connect("HeartJS", {password : "xxxxxxxxxx"}, (err) => {
        if (err) throw err;
      });
    });
  });
}

function dataInterval() {
  timer = setInterval( () => {
    loadData();
    mqtt.publish("agt/sensor/bme280/temp", temp);
    mqtt.publish("agt/sensor/bme280/pressure", pressure);
    mqtt.publish("agt/sensor/bme280/humidity", humidity);
  }, 10000);
}
