i need help how to read blynk_token from portal and assign to blynk.config or blynk.begin?
thanks

Hello, can you give some hints how to use PubSubClient with your WiFiManager?
To init the PubSubClient a WiFiClient is given as parameter...
WiFiClient espClient;
PubSubClient client(espClient);
Works simple and fine. But how to retrieve a PubSubClient instance when using WiFiManager? If you recommend a different MQTT library it would be fine for me as well.
Thanks, Jan Christian
I am at a location where I have maybe 25 AP in range with the same name.
Sometimes the list dumps out immediately, and the page pops up.
Sometimes each one ticks by 1 every 10 seconds, and it takes forever, and the page times out.
I know i can skip scans, but why do you think this is? Maybe i can fix it since I can reproduce easily.
Adding some values to set the ip address in AP Mode.
Add these lines:
IPAddress local_ip = IPAddress(10, 0, 0, 1);
IPAddress gateway_ip = IPAddress(10, 0, 0, 1);
IPAddress subnet_ip = IPAddress(255, 255, 255, 0);
WiFi.softAPConfig(local_ip, gateway_ip, subnet_ip);
to void WiFiManger::begin(char const *apName)
will set the IP Address - maybe needed in some case.
Would be great to set as parameter in main code.
Best regards.
share settings with other data
from that address writes data occupy and how to use EEPROM to store other data?
sometimes when saving I get
*WM: WiFi save
*WM: Sent wifi save page
*WM: Connecting to new AP
*WM: Connecting as wifi client...
Exception (28):
epc1=0x4000df2f epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000073 depc=0x00000000
ctx: cont
sp: 3fff0990 end: 3fff0ea0 offset: 01a0
so you can use the interface for other things than wifi user and password
Hi!
Excellent library, thanks for sharing!
Although, I'm not able to compile it. I'm in a Mac using the original Arduino IDE and installed the ESP8266 libraries following the steps at: https://github.com/esp8266/Arduino
Then, I've added this library, but when I try to compile the example called «AutoConnect» I get this error:
Arduino: 1.6.5 (Mac OS X), Board: "Generic ESP8266 Module, Serial, 80 MHz, 40MHz, DIO, 115200, 512K (64K SPIFFS)"

I've seen a guy with the same issue at:
http://www.esp8266.com/viewtopic.php?p=29587&sid=0ab2ce98b8ece51d93ae1806a5aaa92c#p29587
Any advice?
Thanks again and keep up the good work :)
Your library is called WiFiManager, your files are called WifiManager.h and WifiManager.cpp and the references in WifiManager.cpp - L12 - are for #include "WiFiManager.cpp"
I can't understand how this tested correctly?
Hello, when scanning in our company all Wifi networks are listed 2-3 times.
I didn't had the chance for further investigation; but I assume following reason... We have several access points providing the same Wifi network. Means we can use network XYZ inside the whole building on all floors. So, assumption is that a Wifi network is getting listed multiple times if multiple access points are in range.
Is there a chance putting all items with the same name together?
Thanks, JC
I get this issue every time I try to compile with WiFiManager in my sketch
{
C:\Users\Longo\Documents\Arduino\libraries\WiFiManager-master/WiFiManager.h:113:10: note: in expansion of macro 'DEBUG_PRINT'
void DEBUG_PRINT(Generic text);
^
}
The code compiles once i remove everything WiFiManager related from the sketch, any help would be appreciated.
Thanks, M
I could work on a much better UI by including the Bootstrap library from the CDN, if you are okay with this.
Hello.
I'm invoking startConfigPortal("Lamp settings") when I detect "setup" button pressed in setup() function.
This works well.
Than I have autoConnect().
If for some reason autoConnect fails to connect it enters config mode. How can I make it so that it tries to connect to this network in a loop without entering configuration portal. In short. I only want to enter configuration portal when I request it. I want autoConnect to retry connection till it succeeds.
How to do it?
Also... what is the best method to restart whole chip/program?
After calling On Demand Configuration and configuring new wifi settings via configuration portal I get.
*WM: WiFi save
*WM: Sent wifi save page
*WM: Connecting to new AP
*WM: Connecting as wifi client...
*WM: Connection result:
*WM: 0
*WM: Failed to connect.
*WM: Request redirected to captive portal
WiFi settings are good, because after hard reset module connects to this wifi without any problems.
Sorry for posting this here, But I don't fully understand this yet; I got the example working fine but once
the you get connected how to I use it to start a webserver, Do I refer to the WIFIManager object for the connection?
can someone point me to some examples?
Thanks
Hi guys,
I've updated the lock icon and specified a size to make it HDPi compatible. Can this be added?

This is what i tried:
WiFiManager wifi;
wifi.setTimeout(120); // retry after 2 minutes to connect to a wifi.
if(!wifi.autoConnect(apName)) { // timeut reached
Serial.println("failed to connect and hit timeout");
delay(3000);
//reset and try again
ESP.reset();
delay(5000);
}
// if you get here you have connected to the WiFi
Serial.println("connected!");
currentIp = wifi.localIP();
But I've got the following error:
'class WiFiManager' has no member named 'localIP'
hi, im trying the simple example from wifi manager and when i connect with my android device, it has no problem and gets the ip 192.168.4.3, can connect to 192.168.4.1 and change the settings. but when i try this with my windows laptop it gives me this ip settings:
ip 164.254.145.161
subnet 255.255.0.0
default gateway: none
it wont connect to 192.168.4.1 unless i manually set a static ip like this:
ip 192.168.4.4
subnet 255.255.255.0
default gateway: 192.168.4.1
Thanks for the implementation of my other suggestions.
Here is a new one - maybe you can use WifiMulti.h instead of the single one.
Best regards
Abstract wifi scanning out of handleWifi
so it can be called on its own.
Probably need to abstract most of the html outputters so they can be called internally or used to callout to server->sendContent(item);
externally.
make the code more portable

Am I wrong importing the libraries or is it a WifiManager issue?
Others might have this need, so feel free to integrate my solution. My application has a display but no user input. It's useful to display that the device is in AP mode, waiting for configuration. I did it with a callback function: in WiFiManager.h, public:
void setAPCallback( void (*func)(void) );
and private:
void (*_apcallback)(void) = NULL;
Then in WiFiManger.cpp after WiFi.mode(WIFI_AP);
I added
if( _apcallback != NULL) _apcallback();
and the obvious
void WiFiManager::setAPCallback( void (*func)(void) ) {
_apcallback = func;
}
Feel free to improve. Thanks for the handy library.
Hi,
Nice job !
i'm trying to compile on arduino ide 1.6.5 and have the following result

Error compiling.
Have you an idea of the real source of hostheader / localip compilation problem ?
THX on advance for any help !
Cheers .
First off: awesome work on this library! It is exactly what I'm looking for.
I noticed a weird issue though. I am experimenting with the ESP8266 (Adafruit Huzzah Feather to be specific). In my experiment, I created a console application, so I could interact with it via the serial port. I'm using WifiManager as the connection framework for Wifi. I added a "command line" ability to software reboot the module using ESP.reset();
When I use this method, often times the autoConnect() call fails. That is: Wifi.begin returns 6 but Wifi.waitForConnectResult() starts to return "1", and continues to do so even if I try to run the Wifi.begin / waitForConnectResult() within a loop.
In this case, unless I actually force a disconnect using WiFi.disconnect(), then after a hard reboot, Wifi.begin() and waitForConnectResult() both start to return zero indefinitely In this state, even a hard reboot (using the reset button) in some cases doesn't correct the problem, and I need to re-upload the sketch.
The funny part is though, if I comment out autoConnect() and manually connected via Wifi.begin() inside the setup() routine, it always works, regardless of the reboot method.
I have read that ESP.reset() has its own issues, so perhaps there is something going on there, although once WifiManager fails to connect in this state, it seems that it can't instantiate the WiFi.begin() process (it always returns 0).
I'm happy to provide more info if needed?
First of all: Nice Project! Everyone who starts a Project with the ESP8266 needs this lib! :)
Just a small change:
If you use a Password-Field in the HTML to hide the Password chars,
it also makes sense to use POST in the Form-Method?!
At the Moment the "p" Argument is shown in plaintext in the url, wenn you click save...
This is my Sketch:
#include <EEPROM.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <DNSServer.h>
#include <WiFiManager.h>
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
My error during compiling process:

exit status 1
The weird thing is that sometime I got the error and sometime I doesn't. o.O
I read this somewhere, maybe in the source code, I cant remember.
I get a

*WM: Configuring access point...
*WM: ESP457230
*WM: AP IP address:
*WM: 0.0.0.0
*WM: HTTP server started
And my AP is never available to devices.
Do you know what causes this ?
Make the scan for AP as optional.
In my case there are up to 15 different Networks available - it takes a lot of time to scan and list
all these Networks - sometimes the page did not load at all, i commented out the setting and everything worked fine. So make this feature optional would be great.
int getRSSIasQuality(int RSSI){
// int dBm = WiFi.RSSI();
int quality = 0;
if(dBm <= -100){
quality = 0;
}else if(dBm >= -50){
quality = 100;
} else {
quality = 2 * (dBm + 100);
}
return quality;
}
Any easy way to sort this also, client or server ?

This library is exactly what I need but looks like it doesn't work as it should.
Module starts in AP mode. After entering SSID and password it automatically restarts and reads correct data from EEPROM and successfully connects to my WiFi router.
But as soon as I manually restart ESP-01 it reads false information from EEPROM, refuse to connect and starts AP again.
Here is what I get when restart my ESP manually:

Could not connect to WiFi
Started Soft Access Point
WiFi connected

mDNS responder started

I am reviewing the code to help with the wiki and find something I do not understand.
begin () is called by AutoConnect () but is declared public and I think it should be private.
Not sure if this uses any of your code (not open source) but it is an interesting project which fits in with tzapu's other temperature logger too. I like the idea where you long-press a button to go into config mode.

It would be netter to use a select instead of links for WLAN selection.
I have the latest git pull of both esp8266com and wifimanger. I'm using the calls in setup() just like the examples and the way they've been for a month. I added the parameter to my .setAPCallback() function, but I have the same problem even if I don't set the callback. When my ESP-12 goes into AP mode I can't get the Configuration page (Android, iOS, Win7) at 192.168.1.4. The serial log looks like this:
*WM:
*WM: AutoConnect
*WM: Reading SSID
*WM: SSID:

It repeats as long as something's connected to the AP.
Hi. Thanks for a great library! I'm new to GitHub and I'm not entirely sure where to put a suggestion.
Just a suggestion for devices that could be used offline. Instead of doing a loop in autoConnect()
with timeout and such, you could have the users put the server's handleClient()
calls in their main loop()
. This way the device can do something while offline.
need to provide some simple sample sketches and report to esp8266/arduino
Is there any way to specify a static IP when in station mode?
Does wifimanager interfeere with spi timings? I had a working code that reads rfid cards and after adding wifimanager i get timeouts when looking for a new card present ( the library returns false, but i tracked internaly that it gives a timeout status )
PS: great work!
Can esp8266 lib even detect this ?
Combined with strength logic, this might be neat for a roaming option.
Could also add wildcard ap matching, for example how xfinity and atts free wifi works.
I added the files to standardize the library.
It allows that in a new update, can be made from the Library Manager.
I've spent a few hours trying to figure out why i couldn't change the default AP SSID / password.
The module would come up with the default "AutoConnectAP" and no password,
and seemed to do so regardless of what i did.
Turns out i picked a password which was too short.
Using a password less than 8 characters results in the module using previous saved AP settings.
This is probably intended behavior, but i suggest printing a warning when using passwords <8 characters, or maybe a comment mentioning this.
Hi nice idea.
Ive already implemented similar method in my project but with simple functions.
Fortunately ive found your library which has many functions similar as mine.
By the way, why are you using mDNS, as per the esp8266 arduino page this not supported in
AP mode?
Failed attempt to connect to new AP after receiving user input Wi-Fi credentials.
*WM: Handle root
*WM: Request redirected to captive portal
*WM: WiFi save
*WM: Sent wifi save page
*WM: Connecting to new AP
*WM: Connecting as wifi client...
*WM: Connection result:
*WM: 4
*WM: Failed to connect.
After I reset the Arduino board, WM seems loading credentials properly.
Change HTTP_HEAD to
const String HTTP_HEAD = "<!DOCTYPE html><html lang=\"en\"><head><meta name=\"viewport\" content=\"width=device-width, initial-scale=1, user-scalable=no\"/><title>{v}</title>";
to disable user scaling.
It's more an enhancement than an issue ;-)
Currently the latest network is stored in EEPROM. Would it be possible to store up to 3-4 network credentials.?
The idea is that the WifiManager can then loop thru all credentials. Would be cool when moving between some networks, e.g. use an EPS8266 at home and in company as well.
Thanks, JC
Hi
first many thanks for the wifimanager, i'am very enthusiastic!
I need your support for send pushover message.
I declare first my parameters, this works perfectly, but i dont understand the void loop with my funktion when i press the button. My Arduino compiler send the following error:

When I attempt to connect to the soft access point, the module decides that it wants to reset to boot mode and then attempt autoconnecting again. This happens even when I'm running the example code.
Here's what the serial monitor displays when this occurs:

Any idea why this happens or how I could fix this?
WiFiManager should redirect all IP addresses to configuration page so that the user does not need to specifically know 192.168.4.1.
Hi @tzapu,
I am facing some compile errors while testing the code. The error is somewhat like this
error: 'class ESP8266WiFiClass' has no member named 'psk'
I have checked the ESP8266WiFiClass and it doesnot contain and psk member function.
I am on 1.6.5-947-g39819f0 version of esp8266-arduino.
I am working on similar thing and I have used the apboot code as reference. I am adding extra functionality like GPIO toggling for my RGB bulb.
