wify selectivewith espnodeMcu

By istruttoresp
- Wed Apr 08, 2020 3:10 pm #86399 hi guys.
i'm new with ESP and not so new with arduino but... i'm here asking help.

i'm trying to connect to home wify with ESP but with a basic wify test it'works and with another sketch not.

the strange thing is:
the same sketch, with ssid Home, doesn't works
the same sketch , with ssid lab, in the same network but another AP it works well.

i'm trying to hunderstand the error but nothing to do.
the basic wifi sketch i made use the ESP8266WiFi.h library
the other sketch :
#include <Arduino.h>
#include <ESP8266WiFi.h>
//#include <ESP8266WiFiMulti.h>
#include <WebSocketsClient.h> // https://github.com/kakopappa/sinric/wik ... -libraries
#include <ArduinoJson.h> // https://github.com/kakopappa/sinric/wik ... -libraries
#include <StreamString.h>

//ESP8266WiFiMulti WiFiMulti;
WebSocketsClient webSocket;
WiFiClient client;

I tryied to comment the line with wifi multi because i read this library can store AP data into the flash memory so...though it could be the problem but ...nothing to do.

i tryied with other 2 NodeMcu shield ... same problem.

i think there is a library conflict but i don't know where.

this is the wifi_test code: (this works)

Code: Select all#include <ESP8266WiFi.h>
#define WLAN_SSID       "Home"
#define WLAN_PASS       "BalgaL0nn076"

void setup() {
  Serial.begin(115200);
  delay(10);

  Serial.println(F("Viva la Figa"));

  // Connect to WiFi access point.
  Serial.println(); Serial.println();
  Serial.print("Connecting to ");
  Serial.println(WLAN_SSID);

  WiFi.begin(WLAN_SSID, WLAN_PASS);
  while (WiFi.status() != WL_CONNECTED) {
    delay(2000);
    Serial.print(".");
  }
  Serial.println();

  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // put your main code here, to run repeatedly:

}





The other sketch (works with thetering of phone very well too) but with AP home it doesn't works.
