In the case of the esp programmed in Arduino IDE for some time I have seen a proposal called WIfiManager presented by Tzapu, which allows an agile and fast connection, the first tests are registered since This time we will make a brief introduction to the WifiManager library, I have tested 2 similar versions.

Version 1: WifiManager created by tzapu - creator. Note: they work perfectly, obviously between the 2 libraries there are variations in code implementations and that generates incompatibilities or errors in some functions between version 1 and 2. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. An example has been downloaded from Github and has been cut to make a light and simple version, without the slightly complex functionalities that we will see later, this version will realize the basic configuration of NETWORK credentials.

We have used an ESP 12Ewe have added a button to configure the Wifi and 2 led diodes as indicators. In the case of the previous tests we made a configuration and Wifi connection via DCHP assigned by our router, but there is a method of assigning complete parameters from form:. Although we have only done some testing, WifiManager is a good solution fast and easy it works correctly. We are analyzing the methods used to add and store more parameters, according to the examples a Json file is created in which the parameters are written, this file "config.

I am a bit confused. Thingspeak API appear. Obviously that is something that need to be programmed in your ino file, but I see no explanation of that, just a screenshot of a menu. Question 2 years ago on Step 5. On Kens version of wifi manager, does anybody have some code to allow to enter a custom ip through the portal?

Question 2 years ago on Step 8. Thanks for posting this. Well done. Reply 2 years ago.

Hello, although I have not tried it on an ESP01, considered the memory. More by the author:. About: Share - Learn - Makers. WifiManager This time we will make a brief introduction to the WifiManager library, I have tested 2 similar versions.Your ESP will automatically join a known network or set up an Access Point that you can use to configure the network credentials. Follow these next instructions. This first example is based on the ESP Web Server postwhere you build a web server with an ESP to control two outputs watch the video tutorial below.

View raw code. This loads the next web page, where you can set your Wi-Fi credentials:. You should see a a window similar to the one shown in the figure below. Open your browser and type the IP address. You should see the web server shown below, that allows you to control two GPIOs on and off:. You can use the preceding links or go directly to MakerAdvisor.

This next line is commented by default, otherwise you would need to configure your ESP every time it boots up. First, create a char variable:. Thanks for reading. I know you get out of your way to help us understand whatever topic you are dealing with. For that I really appreciate your excellent tutorials and courses. Maybe you did talk about it somewhere in your site, if this is the case, my apology; and I hope you direct me to the links that address this important topic IMHO.

Make sure you restart your ESP at least one or two times after uploading the sketch with the reset line uncommented:. Make sure you double-check and you have everything updated. Let me know if that solves your problem.

This error appears also on the WiFiManager examples. Any idea? Regards, Sara. Hi Sara, i already did all the things in your suggestions, without success, also i uninstalled all ESP plugins from my arduino IDE and reinstalled it. Now ist works fine! Maybe important for other users with te sam problem …. Anyway, thanks for your help and your great homepage.

It looks like you have a library missing in your Arduino IDE. Make sure you have all the libraries installed that your sketch needs. Hi Yodrack. Thank you for your answer. I tried several sketches dealing with wifi on my ESP I tried AT commandssame problem I thing my ESP is out of order regarding the Wifi section, but other sketches with no realation to Wifi run without any problem.

I checked the antenna if there were a microcut in the wire, I even changed the capacitor between ESPex and antenna, nothing change! I try to open the IP That should definitely work. What do you see in your Serial monitor when you try that?

You should be able to create a pass for your example….GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again.

The configuration portal is of the captive variety, so on various devices it will present the configuration dialogue as soon as you connect to the created access point.

You can either install through the Arduino Library Manager or checkout the latest changes or a release from github. Currently version 0. Github version works with release 2. If it fails it starts in Access Point mode. While in AP mode, connect to it then open a browser to the gateway IP, default You can and should password protect the configuration access point.

Simply add the password as a second parameter to autoConnect. A short password seems to have unpredictable results so use one that's around 8 characters or more in length. The guidelines are that a wifi password must consist of 8 to 63 ASCII-encoded characters in the range of 32 to decimal. Use this if you need to do something when your device enters configuration mode on failed WiFi connection attempt.

Before autoConnect. This gets called when custom parameters have been set AND a connection has been established. Use it to set a flag, so when all the configuration finishes, you can save the extra parameters somewhere. If you need to set a timeout so the ESP doesn't hang waiting to be configured, for instance after a power failure, you can add. When the time passes, the autoConnect function will return, no matter the outcome.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

If you need to set a timeout so the ESP doesn't hang waiting to be configured, for instance after a power failure, you can add. When the time passes, the autoConnect function will return, no matter the outcome. Check for connection and if it's still not established do whatever is needed on some modules I restart them to retry, on others I enter deep sleep.

If you would rather start the configuration portal on demand rather than automatically on a failed connection attempt, then this is for you. Instead of calling autoConnect which does all the connecting and failover configuration portal setup for you, you need to use startConfigPortal.

Do not use BOTH. See example for a more complex version. This could be helpful for configuring stuff like MQTT host and port, blynk or emoncms tokens, just to name a few. You are responsible for saving and loading these custom values. The library just collects and displays the data for you as a convenience. Usage scenario would be:.Are you familiar with WiFiManager?

I have received several suggestions to discuss this subject; so today I will introduce you to this library and its functions.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Remember that with it, we have a greater facility to configure both an Access Point and a Station. For Station mode, we configure through a portal in the browser.

The ESP will initiate a WiFi configuration portal when connected and will save configuration data to non-volatile memory. Subsequently, the configuration portal will only start again if a button is pressed in the ESP module. Using any WiFi-enabled device with a browser, connect to the newly created access point and enter the address Choose one of the networks and enter the password if needed.

Then save and wait for the ESP to restart. At the end of the boot, ESP attempts to connect to the saved network. The autoConnect function is responsible for creating an Access Point. We can use it in three ways. The startConfigPortal function is responsible for creating an Access Point without attempting to connect to a previously saved network.

The setDebugOutput function is responsible for printing debug messages on the serial monitor. These messages are already defined in the library. As you go through the functions, the data will be printed. By default, this function is set to TRUE. The setMinimumSignalQuality function is responsible for filtering networks based on signal quality. The setSaveConfigCallback function is responsible for informing you that a new configuration has been saved and the connection has been successfully completed.

After the creation of the AP, we will access the portal through IP So let's get the available networks, select one and save.

From there, the ESP will restart and attempt to connect to it, and then it will work as a station and no longer as an Access Point.

After entering station mode, you can make the ESP return to Access Point mode only through the button. Note that we have if defined, else, and endif commands. They are conditional to include necessary libraries pertaining to the chip. In setup, we are configuring our WiFiManager in the simplest way. Let's just define the callbacks and create the network. In the loop, we will read the button pin to see if it has been pressed, and then we will call the method to re-enable the AP mode.

Remember that we do not use the resetSettings command. The settings are still saved for the next time the ESP boots. The callback functions, which are associated with events, serve for you to have the exact moment of an operation, in our case, entering AP mode and Station mode.

We can then implement some desired routine, such as retrieving the SSID from the connected network, for example.

Usage scenario would be:. This feature is a lot more involved than all the others, so here are some examples to fully show how it is done. You should also take a look at adding custom HTML to your form. Add the following snippet before autoConnect. There are a couple of examples in the examples folder that show you how to set a static IP and even how to configure it through the web configuration portal.

The options are:. If you get compilation errors, more often than not, you may need to install a newer version of the ESP core for Arduino.No queda otra que cargar un nuevo programa. El problema reside cuando te llevas ese proyecto basado en el ESP a otro sitio donde hay otra red WiFi diferente.

En el caso de que no se pueda conectar a la red WiFi que tiene configurada por defecto, crea un access point o punto de acceso y activa un servidor de DNS y un servidor web.

Por ejemplo si escribes wifiManager. Tengo que aclarar una cosa. Por eso, aunque en este caso no se haya configurado nada, consigue conectarse a una red WiFi. Como puedes comprobar ahora los mensajes son diferentes. El procedimiento es muy sencillo y es muy parecido al que utilizas cuando te conectas a una red WiFi de un hotel o centro comercial.

Vamos a configurar la red WiFi. Estoy seguro que ya te ha pasado probando el ejercicio anterior. Te aconsejo que lo apagues. Si no tiene LED siempre puedes conectar uno. Me voy a saltar todo lo que tiene que ver con WiFiManager. SPIFFS divide la memoria flash reservando parte para el programa y parte para el sistema de archivos. Lo que ocupe cada parte depende de la placa que estemos utilizando. Sin embargo, hay otras alternativas que podemos tener en cuenta. Busca la que mejor se adapte a tu proyecto y la utilizas.
