NodeMcu never passing WiFi.status

Basic Info

Hardware

Hardware: NodeMcu esp8266 Amica
Core Version: ?

Description

I just got my first esp8266 board and tried to upload the WebServer library. And I upload the sketch and on the serial monitor it tells me it never connects. I have tried every single upload speed thinking I may be going to fast for the board but none of them work.

Settings in IDE

Module: esp 8266 built in
Flash Size: ?
CPU Frequency: 80Mhz
Flash Mode: ?
Flash Frequency: ?
Upload Using: SERIAL
Reset Method: nodemcu

Sketch

#include <ESP8266WiFi.h>

const char ssid[] = "************";
const char password[] = "*************";

WiFiServer server(80);

void setup() {
  Serial.begin(74880);
  while(!(Serial.available()));
  delay(10);

  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println("ssid");
  delay(10);
  
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid,  password);

  //This is where it get stuck and just prints never ending dots <----------------------------------------
  while (WiFi.status() != WL_CONNECTED) {  //<-------------------
    delay(500);                                                 //<-------------------
    Serial.print(".");                                           //<-------------------
  }
  Serial.println("");
  Serial.println("WiFi connected");
  
  server.begin();
  Serial.println("Server started");

  Serial.println(WiFi.localIP());
}

void loop() {
  WiFiClient client = server.available();
  if (!client) {
    return;
  }
  
  Serial.println("new client");
  while(!client.available()){
    delay(1);
  }
  String req = client.readStringUntil('\r');
  Serial.println(req);
  client.flush();
  
  if (req.indexOf("/hi") != -1)
  {client.print("hi");}
}

Try to call wifi_station_get_connect_status() and check the reason why connection request failed.

[tonton81]

sounds like bad ssid/pass

[Ethan17155]

I have tried all 4 of my Wifi connections, none of them work.

[Pablo2048]

No info, no help :-( ... Do as i wrote and give us what wifi_station_get_connect_status() returns.

[Ethan17155]

How do I use the wifi_station_get_connect_status()?

[Pablo2048]

Did you try at least to search the web, or are you too lazy?

extern "C" {
#include "user_interface.h"
}
....
_status = wifi_station_get_connect_status();
....

[Ethan17155]

I tried using a Serial.print(WiFi.status()); inside the: while (WiFi.status() != WL_CONNECTED) {...} and it comes back as 6 for a while but then goes to 1.

[Pablo2048]

wifi.status gives only arduino shield compatible results (why i'm wasting my time to suggest something when nobody listen :-( ) but in this case it means that you have written bad ssid to ssid[] - what exactly did you put into ssid[]?

[Ethan17155]

my wifi name

[Ethan17155]

my wifi ssid and wifi name is the same

[Pablo2048]

So we have two options:

1. you give wrong ssid/pass pairs
2. do what i already twice suggest, because we can get more info
   I'm assuming that your AP is 2.4GHz one, not 5GHz...

[Ethan17155]

I did a Serial.print(wifi_station_get_connect_status()); and it printed 1 for a while then went to 3.

[Pablo2048]

So you can interpret by yourself - just take a look into user_interface.h for station_status_t. It seems like status is STATION_NO_AP_FOUND. What is the type of your AP?

[tonton81]

wrongly typed, maybe hidden ssid, or 5ghz AP, theres reasons why its not seen

[Ethan17155]

my AP is 2.4ghz

[Pablo2048]

You are really not giving much info, so briefly:
write sketch which scan wifi for available AP's (STFW for examples) and try to figure out why your ESP did not see your AP.

[Ethan17155]

WiFiScan is not picking up my wifi or mobile hotspot.

[Pablo2048]

Standard, channel, SSID?

[Ethan17155]

Here is all the info on the WiFi:

SSID: **************
Protocol: 802.11n
Security type: WPA2-Personal
Network band: 2.4 GHz
Network channel: 6
IPv4 address: 192.168.1.57
IPv4 DNS servers: 192.168.1.1
Manufacturer: Intel Corporation
Description: Intel(R) Dual Band Wireless-AC 8260
Driver version: 19.50.1.6
Physical address (MAC): 44-85-00-FB-8E-D9

http://www.esp8266.com/viewtopic.php?f=6&t=1612 hope that you really don't have SSID as ************ (really don't know what is so secret on broadcasted SSID)

[Pablo2048]

probably more relevant #3941 ...

[tonton81]

with the latest git im able to connect to my iphone7+’s AP without issue, and it’s a dual band phone. it also has no issues connecting to a crappy Bell router either :)

[Ethan17155]

The Board itself does not read newer WiFi connections, all my connections are less than a year old so I am thinking that is the reason.

[Ethan17155]

more specifically: 802.11n AP.

[tonton81]

no, its not, did wifiscan see any APs at app?

[tonton81]

*all

[Ethan17155]

no

[Ethan17155]

I might have a bad board?

[tonton81]

it sounds like it, can you try another?

[Ethan17155]

It should support it because the wifi block on the board says: 802.11b/g/n

[tonton81]

yeah but if you dont see any APs, something is definately wrong with the chip i would presume

[tonton81]

i get 20 APs listed from my livingroom
are you in the middle of nowhere with only ur two APs? :D

[Ethan17155]

This is my first NodeMcu Esp8266 board, but I have used an Adafruit Feather Huzzah and it worked perfectly fine. So I will buy a Huzzah and see if that works.

[Ethan17155]

nowhere-ish, My computer picks up our Ethernet, our 4 Wifi connections, our printer, and two others wifies near us that are very weak.
