    I don't think it's that, because it happens in both situations. It doesn't matter if it's connected to USB adapter or PC with Espruino IDE running.
    When I have the wifi error, the board works without any issues, I just can't get the wifi to work.
    When everything is working normal again, I see the red power up flash and instantly the blue flashing from the ESP connection.

    The main power sources I'm using are the USB hub connected to my macbook, a standard USB hub adapter with a power source and an old USB charger.

    It looks like the error is not happening when I'm sure the wifi connection is closed each time I disconnect the USB . But that could be a coincidence as I have no idea what's going on :)

    Sorry for bringing this up again but it was still bugging me :)

    I keep getting this error from time to time and it keeps me from finalising the project.
    When I have the error, the board is unusable for some time and after a lot of trail and error it works again.

    But last weekend I think I might have found what the cause of the error is. So I want to check with you if this could be possible.

    When I unplug the USB and the ESP is in the middle of doing something (?) it gets 'locked' with the error. Now I added a wifi.disconnect() after I requested my data.
    I first did some tests with the wifi.disconnect on button click just before I disconnect the USB and since I'm doing that the board and ESP boot without any issues.

    So I really hopes this solves my issue :)

    OMG, I was about to try to desolder the ESP8266 and replace it with another one I had when I thought to give it one more go. And yeah guess what, it worked :D

    I have no idea what did the trick. Very frustrating that I have no idea what the issue was :)

    But it works! That's the most important thing. Thank you very much for looking into it!
    I'll try to write down all steps with all source files in an instructable and share the link.

    And then buy more espruinos and have more fun with them ;)

    Nope, nothing is printed.

    so it's really going to be stressing whatever you've connected it to

    Is it a bad idea to attach the LED strip directly to those pins?
    It's always a max of 10 neopixels that will be toggled on and off.
    I'm making some kind of weather station that gets the data from an API so eventually I want to plug my device into a socket with a USB supply and keep it running for days.

    The value is between 3.31 and 3.04.

    I have a LED strip soldered to the + - and B15
    When LEDs are active around 3.0
    After removing the wires again the values are a little higher, between 3.312 and 3.315

    When I remove all unrelated code in my program I get the same error.
    Same when I uploaded your snippet.
    I erased all storage and used reset to clear the RAM but nothing helps.

    The LED strip is still working as expected.

    Could I have damaged the ESP8266 in some way?

    I always had my espruino connected to my laptop, I'm not 100% sure but after I plugged the USB into a standard android phone USB power plug it stopped working.

    Typically it was the moment that I finalised my project and wanted to show it the first time to someone else it died. So frustrating :)

    BTW any idea when the Espruino WIFI will be back in stock?

    I was running some code on the Espruino Wifi without any issues, but suddenly after reconnecting my Espruino to the WebIDE I get this error.

    I tried resetting and flashing my Espruino, removing all local code, clearing the cache, uploading something else but nothing changes. It's like the Wifi module is in some kind of locked state.
    I have no idea how to fix it. I hope anyone else could help me?

    This is the code I use to connect to my Wifi

    const WIFI_NAME = "******";
    const WIFI_OPTIONS = { password : "*******" };
    function onConnected(err) {
        if (err) {
            console.log(err); // This returns the No 'ready' after AT+RST
            setTimeout(connect, 5000);
        } else {
            wifi.getIP(function(e,ip) {
                connected = true;
                setInterval(getWeather, 1800000); // once every 30 minutes
    function connect() {
        wifi = require("Wifi");
        wifi.on('connected',function() {
            console.log("Connected to WiFi");
        wifi.on('disconnected',function() {
            console.log("Disconnected from WiFi");
        wifi.connect(WIFI_NAME, WIFI_OPTIONS, onConnected);
    E.on('init', function() {
