ESP8266WebServer not serving under WiFiManager?
Posted: Thu Mar 16, 2017 12:31 pmHi
I'm trying to use WifiManger, and used AutoConnectWithFeedbackLED as a based, just adding ESP8266WebServer so that I can serve up some information (/test) after it's online. However, I can't open port 80 to the reported IP using my browser. Here's my code:

Code: Select all
#include <ESP8266WiFi.h> //https://github.com/esp8266/Arduino
//needed for library
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h> //https://github.com/tzapu/WiFiManager
//for LED status
#include <Ticker.h>
const int ledPin = 5;
const char* ver = "WiFi Manager Test 1.00";
Ticker ticker;
ESP8266WebServer server(80);
unsigned long startTime = 0;
void tick()
{
//toggle state
int state = digitalRead(ledPin); // get the current state of GPIO1 pin
digitalWrite(ledPin, !state); // set pin to the opposite state
}
//gets called when WiFiManager enters configuration mode
void configModeCallback (WiFiManager *myWiFiManager) {
Serial.println("Entered config mode");
Serial.println(WiFi.softAPIP());
//if you used auto generated SSID, print it
Serial.println(myWiFiManager->getConfigPortalSSID());
//entered config mode, make led toggle faster
ticker.attach(0.2, tick);
}
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
startTime=millis();
//set led pin as output
pinMode(ledPin, OUTPUT);
// start ticker with 0.5 because we start in AP mode and try to connect
ticker.attach(0.6, tick);
//WiFiManager
//Local intialization. Once its business is done, there is no need to keep it around
WiFiManager wifiManager;
//reset settings - for testing
//wifiManager.resetSettings();
//set callback that gets called when connecting to previous WiFi fails, and enters Access Point mode
wifiManager.setAPCallback(configModeCallback);
//fetches ssid and pass and tries to connect
//if it does not connect it starts an access point with the specified name
//here "AutoConnectAP"
//and goes into a blocking loop awaiting configuration
if (!wifiManager.autoConnect()) {
Serial.println("failed to connect and hit timeout");
//reset and try again, or maybe put it to deep sleep
ESP.reset();
delay(1000);
}
//if you get here you have connected to the WiFi
Serial.println("connected...yeey :)");
ticker.detach();
//keep LED on
digitalWrite(ledPin, LOW);
server.on("/test", handleTest);
}
void handleTest() {
int rssi=WiFi.RSSI();
String wifiSSID=WiFi.SSID();
String s = "OK.<BR>Uptime: "+String((millis()-startTime) / 1000 / 60 / 60)+" hours"+
"<BR>WiFi AP: "+String(wifiSSID)+
