Good afternoon, everyone!
I'm trying to use this Board:
https://aliexpress.ru/item/32813202006.html?spm=a2g0o.productlist.0.0.7b062fee3ouO7n&algo_pvid=2185e518-c4cf-4acb-8ec0-79f12d1a284e&algo_expid=2185e518-c4cf-4acb-8ec0-79f12d1a284e-24&btsid=0b8b035615861624296867196ebcdd&ws_ab_test=searchweb00,searchweb201602,searchweb201603_

Problem connecting to wi fi
```
var wifi = require("Wifi");
function onInit() {
   wifi.stopAP();
   wifi.connect("TEST1234", {password: "12345678"}, function(err) {
      console.log("connected? err=", err, "info=", wifi.getIP());
     });
}

I tried all possible options. If you flash the Arduino IDE Board, everything connects without problems.
What might be the problem?

Hi @Alexandr, the link in post #1 and the title at the destination indicate a D1 Mini, but a true mini only has 16 pins, not 30!

I see that you are a long time user of the ESP8266. As both errors occur inside the onInit, as a wild guess, it might be that stopping an AP before it is even created is causing the error. Has an attempt to place the internal code inside a try/catch block been attempted to see if any errors are bubbling up and not being caught?

Until others are able to respond, take a look at some running code snippet examples that might give some insight:

STA or AP mode browser unable to connect to ESP8266-12

Posting snippet results of what does work, may provide some clues also.

Also take a look at support options for NodeMCU:

Thanks for the answer. I want to add that on other models of esp8266 everything works perfectly. It is not clear why wifi does not work on this Board.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

Mention another user by @username

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
