No need of writing wifi credentials in the code | ESP8266 Smart Config | ESP8266 projects

[@jacquesgilbert2774]

Nice, but you can do as well or, in my opinion, better with the WiFIManager library for ESP8266: 1- It does not require a mobile app, you can configure it from a browser 2- It stores the credentials in non volatile memory so you don't need to reenter them 3- It works well with ArduinoOTA, which allows you to upload program updates via WiFi 4- I am weary of using a mobile app, where I cannot see all the code and I cannot be certain that it will be updated and work with the next version of the OS.

[@vishnudileesh1243]

Any help on doing the same with mongoose os? Thanks

[@achhintkumarupadhyay4363]

Could you please explain how to do the same thing using WiFIManager library ?

[@LatinDanceVideos]

Thanks for the tip. This looks promising randomnerdtutorials.com/esp32-over-the-air-ota-programming/

[@ghazaleahmadi5729]

is it possiable to use this library for esp32?

[@BrianLough]

You should check out WiFi Manager (search for esp8266 wifi manager) - It will try connect to the last used WiFi details - If that fails it will create a new access point which you connect to with your phone - You then open your web browser on your phone and it will redirect you to the page automatically, put in your wifi details. - It will then restart your esp8266 and repeat the above So it doesn't require an app or it only asks for details when its needed.

[@utkarshdeoli]

well but app is more convinient if you want to make a fullfleded product you can just program an app and everything in that app so that the coustomers don't need to close the app

[@boontecklee3361]

Very helpful video. I have 2 questions: 1. If I have a network of 3 or more ESP32, how do I direct the settings to each of them? 2. How can I protect the ESP credentials from being changed by unauthorized person with the same method?

[@billcaruso7050]

Thank you! You always make tough problem solutions easy to understand and implement! Now I can, thanks to you, deploy an ESP8266-based wifi product I have been thinking about for several months!

[@bibekthapa1154]

in my case, it is working but whenever electricity is gone, it require ssid and password to be inject.

[@ashvlogs6556]

ESP8266 Nodemcu i have sucessfully finished all the steps correct connected it to com 6 because while connecting to com3 it was showing error but for some reason after the actual wifi is connected it still shows network not available and when i am trying to reset i am not ale to help me Also now when I am seeing the WiFi name is also not available and when I tried re uploading the code in 0x00000 etc and redoing still not working pls help me

[@jesperkped]

Yeah, I just hope you don't get uninvited guests that reconfigure your devices. If this was to be an option in my home, there had to be some sort of administration check to allow for the change of the wireless settings.

[@techiesms]

Can this work with esp32?

[@MrTalhakamran2006]

So what will happen when the board will get powered off and is powered on again. Will it remember that user id and password. Since you provided the ssid and passwd in setup via cellphone when it will restart will it be waiting for your cellphone to send the wifi password?

[@subhabratabasu266]

But in any case if the esp8266 get turned off After turn it on again the esp8266 doesn't connect with the previous wifi automatically So if you have any solution regarding this please tell me

[@tushthushan5590]

Is there no way to stop the reset on a power on ?. Because all the relays are on.

[@jithin_isaac]

hey great work! but this process needs to be done everytime the esp is reset/powered off right? Isn't that not serving the purpose finally? can the entered ssid and password be stored into the memory of the esp in some way?

[@techiesms]

Yes we can store it in eeprom But see, all this depends upon the application of your project For some projects, my code will perfectly work While in some other your idea will work

[@jithin_isaac]

techiesms yeah that true.. We can put the smartconfig code under an if loop and call it whenever we want to change the ssid-password by the click of a extra button placed on the pcb.. and then store these credentials in the eeprom.. thanks!

[@techiesms]

Yaa exactly That’s the perfect process

[@oscargr_]

There are better ways. I made a internet clock with a small TFT display that I can switch into "setup" mode if I need to switch it to another WiFi network. I copied that part of the code from internet, not claiming it's my own. Basically the trick is to store the credentials in eeprom at runtime. So next time you power on, it checks if credentials are stored. If yes, use those, if those can't connect, go into "setup" mode.(where you can change credentials and store those in eeprom) Google is your best friend.
