Description

Hello

The autoconnect method didn't work with a Wemos D1 Mini
It didn't start

Settings in IDE

Module: Wemos D1

Additional libraries:

Sketch


#include <ESP8266WiFi.h>

#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>

#include <string>

void setup() {
  Serial.begin(115200);
  Serial.println("start...");
  pinMode(LED_BUILTIN, OUTPUT);
  WiFiManager wifiManager;
  /*char string[] = "Smart_Device_";
  String mac = WiFi.macAddress();
  mac = mac.substring(9);
  mac.replace(":","");
  String temp = strcat(string, mac.c_str());*/
  digitalWrite(LED_BUILTIN, HIGH);
  wifiManager.autoConnect();
  //if you get here you have connected to the WiFi
  Serial.println("connected...");
}

void loop() {
  if ((WiFi.status() == WL_CONNECTED))
  {

    // TODO Build Webpage for ACB in here
    for (int i = 0; i < 10; i++)
    {
      digitalWrite(LED_BUILTIN, HIGH);
      delay(1000);
      digitalWrite(LED_BUILTIN, LOW);
      delay(1000);
    }
    
  }
