Espruino Wifi module not responding

[espruino-discuss]

Posted at 2024-01-06 by Coder2012

I am trying to use my Esprunio Wifi, I just updated it to v2.19 firmware successfully and I am trying to connect to my wifi router, something I've done over 100 times in the past. Unfortunately i'm getting an error.

I saw that its possible now to update the Wifi firmware also, it does query the module and gets the current version but trying to update the firmware fails for some reason.

Not having much luck coming back to play with my devices both my Pico and the Esp Wifi giving me problems, hope someone can help me.

I also took some time to try and debug using the following code I saw on another thread:

This is the code you said to try:

var WIFI_BOOT = A13;
var WIFI_CHPD = A14;
digitalWrite(WIFI_CHPD, 0); // turn off wifi
var pins = { rx: A3, tx : A2 };
Serial2.on('data', function(d) { console.log("wifi:",JSON.stringify(d)); });
Serial2.setup(115200, { rx: A3, tx : A2 });
setTimeout(function() {
  digitalWrite(WIFI_BOOT, 1); // out of boot mode
  digitalWrite(WIFI_CHPD, 1); // turn on wifi
}, 500);

And this is the output

@Coder2012,

I'm surprised that you do low-level communication to the ESP-##/ EX8266 module sitting on the Espruino-Wifi... Your code reminds me of using Pico with an ESP-01. As far as I recall, this is all hidden behind Espruino-Wifi firmware... No need to deal w/ GPIO pins and the like.

Take a look at this conversation EspruinoWiFi module builtin? and, for example, at this code example: EspruinoWiFi module builtin? - where Espruino-Wifi connects to the local Wifi and exposes a WebServer / interactive WebPage to control the train; and here is another example... not showing me in the best light, but it shows how to connect Espruino-Wifi and check the ip address your access point w/ DHCP give the connection Espruino/Wifi - getIP() returns undefined but callback receives null,ip.

Updating the onboard ESP-## is though a different story... but there is documentation about it... https://www.espruino.com/WiFi

(@gfwilliams, ooops, read The Espruino WiFi board is now discontinued. We will be releasing a new WiFi + Bluetooth board in 2022... I guess COVID-19 and related supply chain challenges ask for a special interpretation of the number 2022... :\ )

@allObjects

Thank you for the reply, the low-level code above was taken from another post that Gordon commented on, he wanted to see what the wifi module reported back, so just to save time I decided to do the same.

The code I am actually running is as follows:

const WIFI_NAME = "<REDACTED>";
const WIFI_OPTIONS = { password : "<REDACTED>" };
const wifi = require("Wifi");
let mqtt;

const server = "172.24.0.2"; // the ip of your MQTT broker
const options = {
  // ALL OPTIONAL - the defaults are below
  client_id: "random", // the client ID sent to MQTT - it's a good idea to define your own static one based on `getSerial()`
  keep_alive: 60, // keep alive time in seconds
  port: 1883, // port number
  clean_session: true,
  username: "username", // default is undefined
  password: "password", // default is undefined
  protocol_name: "MQTT", // or MQIsdp, etc..
  protocol_level: 4, // protocol level
};

let id = null;
let temp = 0;
let running = false;
let speed = 50;
let rgb = {r: 128, g: 128, b: 128};
const leds = 12;
let isActive = false;

const onInit = () => {
  lightsOff();
  lightsOn(rgb, 300);
  wifi.on('disconnected', connect);
  connect();
};

const connect = () => {
  console.log("wifi connecting...");
  wifi.connect(WIFI_NAME, WIFI_OPTIONS, (err) => {
    if (err) {
      console.log("wifi error", err);
      return;
    }
    console.log("wifi connected");
    connectMQTT();
  });
};

const connectMQTT = () => {
  console.log("connecting to mqtt");
  mqtt = require("MQTT").create(server, options);

  mqtt.on("connected", () => {
    console.log("mqtt connected");
    lightsOff();
    lightsOn({r: 0, g: 128, b: 0}, speed);
    mqtt.subscribe("espruino/rgb");
    mqtt.subscribe("espruino/speed");
   // mqtt.subscribe("outdoor-motion-sensor");
  });

  mqtt.on("publish", (pub) => {
    switch (pub.topic) {
      case "espruino/rgb":
        rgb = JSON.parse(pub.message);
        lightsOff();
        lightsOn(rgb, speed);
        break;

      case "espruino/speed":
        speed = pub.message;
        lightsOff();
        lightsOn(rgb, speed);
        break;

      case "outdoor-motion-sensor":
        const activity = JSON.parse(pub.message).activity;
        if(isActive === activity){
          return;
        }else{ 
          isActive = activity;
        }
        const color = isActive ? {r: 255, g: 0, b: 0} : {r: 0, g: 255, b: 0};
        speed = isActive ? 200 : 1000;
        lightsOff();
        lightsOn(color, speed);
        break;
    }
  });
  
  mqtt.on("error", (err) => console.log("error", err));

  mqtt.connect();
};

const lightsOn = (color, speed) => {
  if (running) return;

  let rgb = new Uint8ClampedArray(leds * 3);
  let pos = 0;

  const getPattern = () => {
    pos = (pos + 1) % leds;

    rgb[pos * 3 + 0] = color.g;
    rgb[pos * 3 + 1] = color.r;
    rgb[pos * 3 + 2] = color.b;

    for (var i = 0; i < leds * 3; i++) rgb[i] *= 8 / leds;

    return rgb;
  };

  id = setInterval(() => {
    A15.set();
    require("neopixel").write(B15, getPattern());
    A15.reset();
  }, speed);
  running = true;
};

const lightsOff = () => {
  clearInterval(id);
  let rgb = new Uint8ClampedArray(leds * 3);

  const getReset = () => {
    for (let i = 0; i < rgb.length; ) {
      rgb[i++] = 0;
      rgb[i++] = 0;
      rgb[i++] = 0;
    }
    return rgb;
  };

  A15.set();
  require("neopixel").write(B15, getReset());
  A15.reset();
  running = false;
};

const getRndColor = () => {
  let color = {
    r: Math.round(Math.random() * 255 + 25),
    g: Math.round(Math.random() * 255 + 25),
    b: Math.round(Math.random() * 255 + 25),
  };
  return color;
};

The error message is returned here:

if (err) {
      console.log("wifi error", err);
      return;
    }

Odd about the firmware update error, but the 0.40 ESP8266 firmware should still be basically fine.

Thanks for running the debug code above - you can see `WIFI GOT IP` in the log, which shows that the module itself is working and has connected to the network, so I wonder what's going on...

Please could you try upgrading to a cutting edge build? I seem to recall that 2v19 had an issue with the minified ESP8266 code which might be causing problems - I was going to push a 2v20 release but didn't want to do it before Christmas in case it broke something.



--------------------------------------------
Posted at 2024-01-08 by @allObjects

@Coder2012,

dug up my Espruino-Wifi... 2v01... a while updated it to 2v19 and and checked ESP8266 firmware:

var t = `
Ai-Thinker Technology Co.,Ltd.

ready
AT+GMR

AT version:0.40.0.0(Aug 8 2015 14:45:58)
SDK version:1.3.0
Ai-Thinker Technology Co.,Ltd.
Build:1.3.0.2 Sep 11 2015 11:48:04
OK
`;

Using just the Wifi connection part from your code w/ time added in loggin :

// EspruinoWifiCheck.js
// 2024-01-08_ao
// after update to 2v19 from 2v00, w/ ESP8266 v4.0
const WIFI_NAME = "";
const WIFI_OPTIONS = { password : "" };
const wifi = require("Wifi");

const t = (n) => { var t = getTime(); t=""+t;
return t.substr(t.indexOf(".")-(n||2)); };
var wc = "wifi connect";
const connect = () => {
console.log(t(),wc+"ing...");
wifi.connect(WIFI_NAME, WIFI_OPTIONS, (err) => {
if (err) {
console.log(t(),wc+" error", err);
return;
}
console.log(t(),wc+"ed");
wc = "wifi re-connect";
});
};

const onInit = () => {
wifi.on('disconnected', connect);
connect();
};

setTimeout(onInit,999);

And to my dismay, I get nothing different than:

You obvious dug further... My Wifi had still this [Retro Horse Derby Game Board with Neopixels showing Reaction Game Status](https://forum.espruino.com/comments/14612107/) code on it, which was not (yet) using Wifi (the intent was to store game results via Wifi in some (google) doc / db in the cloud), but I know Wifi at worked before (obviously like your's too...).

I'll restore older Espruino version and try again...

@Coder2012,

used the binary approach and figured that 2.15, 2.17, 2.18 work. So I doubted my earlier confirmation that 2v19 failed. But: it kept failing... So now back to 2v18... (and some chat w/ @gfwilliams).

I noticed that connection could be made within the range of 8..12 seconds, but failing was always within 10..11  seconds:

Did you try a cutting edge build? I'm pretty convinced it is fixed in those

Posted at 2024-01-08 by @allObjects

@gfwilliams, @Coder2012

The cutting edge build `espruino_2v19.123_wifi.bin` from https://www.espruino.com/binaries/travis/master/espruino_2v19.123_wifi.bin does it [EDITED: BUT WATCH: this is fluid... go to the [Espruino Download]
(https://www.espruino.com/Download) page,  `Find a Binary` section, `select the board`,  and pick the `Cutting Edge build` link - at the bottom of the build(/release) list].

Hey that's great to hear you were able to reproduce this issue and also have a fix. How would I flash the device with this firmware, hopefully it can be done with the web ide?

@allObjects The link above to the *espruino_2v19.123_wifi* binary is 404 for me :(

I checked in github but can't see it in any of your repos.

--------------------------------------------
Posted at 2024-01-08 by @gfwilliams

Try `https://www.espruino.com/binaries/travis/d594469bcd5cdf1c28de321325565f8a8875184a/espruino_2v19.123_wifi.bin`

The last link was the latest firmware and I'd since made *another* change, so the number had changed from 122 to 123. This one should stay the same.

You can just paste it into the IDE and you'll be fine

--------------------------------------------

Sorry for the confusion... updated the original post and repeat it here again for who ever will come across same need...

Hi @allObjects and @gfwilliams thank you for your time with this, I got the notification for updating to 2v20 in the Espruino web ide this morning, and now the Wifi module is connecting as expected again!
