Hola amigos del foro!
Es un placer volver a estar por aquí =)
Estoy aprendiendo a desarrollar proyectos IoT con ESP.
Actualmente estoy implementando AsyncWifiManager para poder configurar el dispositivo una vez colocado en destino.
Adjunto código:
#if defined(ESP8266)
#include <ESP8266WiFi.h> //https://github.com/esp8266/Arduino
#else
#include <WiFi.h>
#endif
//needed for library
#include <ESPAsyncWebServer.h>
#include <ESPAsyncWiFiManager.h> //https://github.com/tzapu/WiFiManager
AsyncWebServer server(80);
DNSServer dns;
// select wich pin will trigger the configuraton portal when set to LOW
// ESP-01 users please note: the only pins available (0 and 2), are shared
// with the bootloader, so always set them HIGH at power-up
#define TRIGGER_PIN 2
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
Serial.println("\n Starting");
pinMode(TRIGGER_PIN, INPUT);
}
void loop() {
// is configuration portal requested?
if ( digitalRead(TRIGGER_PIN) == LOW ) {
//WiFiManager
//Local intialization. Once its business is done, there is no need to keep it around
AsyncWiFiManager wifiManager(&server,&dns);
//reset settings - for testing
//wifiManager.resetSettings();
//sets timeout until configuration portal gets turned off
//useful to make it all retry or go to sleep
//in seconds
//wifiManager.setTimeout(120);
//it starts an access point with the specified name
//here "AutoConnectAP"
//and goes into a blocking loop awaiting configuration
//WITHOUT THIS THE AP DOES NOT SEEM TO WORK PROPERLY WITH SDK 1.5 , update to at least 1.5.1
//WiFi.mode(WIFI_STA);
if (!wifiManager.startConfigPortal("OnDemandAP")) {
Serial.println("failed to connect and hit timeout");
delay(3000);
//reset and try again, or maybe put it to deep sleep
ESP.reset();
delay(5000);
}
//if you get here you have connected to the WiFi
Serial.println("connected...yeey :)");
}
// put your main code here, to run repeatedly:
}
Es el código de ejemplo de la librería AsyncWifiManager. ENLACE
El problema es que no consigo entrar el portal cautivo, en el terminal aparece sin parar:
About to scan()
About to scan()
Scan done
About to scan()
About to scan()
Scan done
...
Los que estén metidos con el tema ESP y los que no y sepan ayudar, gracias de antemano por la ayuda.
Llevo 3 días detrás de ésto y no logro dar con el clavo.
Un saludo. Gracias por su tiempo.
