Let the ESP8266 auto connect to an open wifi network.
With this library an ESP8266 can automatically connect to an open wifi network which has a working internet connection. This library should not be considered save since it is a bad thing to have your iot autoconnect to everything it can get a hold of. However I developed it for a personal use case where exactly that was required. So here we go :)
First, include the library in your sketch and initialize a new instance:
#include <ESP8266AutoConnect.h>
int LED_DISCONNECTED = 15; //D8
int LED_CONNECTING = 13; //D7
int LED_CONNECTED = 12; //D6
#int LED_CONNECTED = 0; //No indicator led for an online connection
ESP8266AutoConnect ac(LED_DISCONNECTED, LED_CONNECTING, LED_CONNECTED);
If you don't want to use any indicator led just ignore them:
#include <ESP8266AutoConnect.h>
ESP8266AutoConnect ac;
Next, simply call the ac.autoConnect() function. It won't continue until it has established a connection.
void loop() {
ac.autoConnect();
delay(1000);
}
All available methods:
void ac.autoConnect();
bool ac.ping(String host, int port);
void ac.setDisconnectLed(int); //Default = 0 (unset)
void ac.setConnectingLed(int); //Default = 0 (unset)
void ac.setConnectedLed(int); //Default = 0 (unset)
void ac.setBlinkDelay(int); //Default = 250
void ac.setPingHost(String); //Default = "www.google.com"
void ac.setPingPort(int); //Default = 443
