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=searchweb0_0,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.
