WiFi credentials stored in EEPROM | Better than Smart Config | ESP8266 projects | LCSC | SBU

In this video, I have shown how you can enter the wifi credentials in you esp8266 boards over the air without hard programming it.
Not only that, you can also save that credentials inside EEPROM of ESP8266.

I am not from electronic background but enthusiastic towards these things .I have learnt a lot from internet and you tube but you are truly genius bro. I love the way you explain the things. Thanks a lot for sharing information and knowledge bro.

[@techiesms]

Amazing Now just do one thing Share video to share knowledge

[@mfanwar67]

You are great man and this comment coming from neighbor I hope you understand. Keep it up. You are a position person.

This is the most important video of this channel.

[@sayantanpal7953]

WifiManager library by tzapu can also be an option. And I personally like it because it provides better interface.

[@Shiv4717]

Sayantan Pal I need help

[@jynkotech]

This video is very use full to me but if you make a video that How to make a product to control home appliances and also make a application for it and in this app we should also change the ssid and pasword.

[@diptangshudas6725]

Finally, what should I do if I want to remove the stored WiFi credentials in the EEPROM of ESP8266?

[@tridwipdhali]

I also have the same question sir... Please reply

[@jynkotech]

sir you are a great youtuber

[@ubiquitousingit]

Nice info. Things like these keeps the creativity alive. However, using the wifi library and captive portal could be an option too! No need to know and type the IP address, just connect to wifi and let the captive portal take you to the config page.

[@vonries]

That is great! I am sho surprised that I haven't seen someone show this before. It just seems like such an essential tool.

[@tomazis100]

Hi GREAT VIDEO!! How can we center the web page in the middle of the monitor? Thanks in advance!

[@suneetasandeep]

Hi Sachin. One mre usefull project. Short and simple. i was thinking one more option. now take an example. i am end user of one project implemented with your code. i dont have arduino IDE on my laptop. so, when AP is connected successfully i should get one green light connected on one pin on nodemcu so that user should come to now of successfull connection. afer that only he should connect to his wifi and later on successfull connection to his home network, the same green led should blink 5 times and then your led blink code should come (or actual code), what say

[@er.munishsharma4343]

[@tusharshahi1724]

Sir, pls. Teach us coding for iot. Products so we can make our own new projects without copying and all. Teach us the language required to program all this specially nodemcu

[@HaTaKeSeMpAi]

I have a doubt. How do I know what is the hotspot that the ESP8266 gives me without connecting it to a serial port? Is there not an option for the hotspot to be fixed? Thanks for sharing this video, it helped me a lot.

[@skprojects1532]

This also possible with the esp WiFi manager library. But the problem is that we can decorate the local page created by the esp. and i want make designed the local host page as responsive. Thank you so much for this video ❤️

[@biofilamentcorp6251]

Thnx for the shared knowledge sir ; this extremly usefull info..i was wondering if by any chance You can put the equivalent libraries for the esp32... Regards from México

[@dhavalshukla6615]

I have been trying to store the data to another string like you do in this with esid variable and saving it, but to no luck, before I think I could do it, and it could connect but now for some reason that doesn't seem to be working, idk what to do, I am doing the same as you, but what I have is ESP32-WROOM32D board, and I tried checking it various ways, not sure what is wrong.

[@maliarif2023]

Your method is simply Awesome! Quite simple and useful. Thank you.

[@muhammadbilal2000]

Hello, thank you for the great video. Can you please make a video on the ESP32 becasue the same code isn't going to work on ESP32, isn't it? Or what changes do I need to make for ESP32 to make it work? Thank you

[@raymondmichael4987]

Very informative, but your way of switching from code to your desk is really annoying, keep yourself at a corner and rest of the screen present the code . Just my thoughts 💭 😊

[@burhanuddinbhiwaniwala618]

GREAT VIDEO sir.... I was thinking is it possible to use Nextion display to enter WiFi credentials without hard coding or without creating a Soft AP

[@tharunv7264]

Really awesome... Can u pls say what changes have to be made in the code for ESP32?

[@Abhishekkumar-cj3ic]

Use Wifi manager library it is the best..!! and have support for ESP32 also

[@zohaibgilani1609]

is this stored in EEPROM , as writing other code , the wifi credential in esp32 remain same? And kindly make vedio on esp32 changing wifi credentials and also blynk is being used in it.

[@mustafataha717]

so any code wouldn't work if esp not connsected to wifi? what if we need a code work even it not connected to any wifi

[@sam6124023]

There is one problem, that if the router and esp both restart at same time, esp boots ahead of router and since the eprom credentials not available as the router is still not available, it goes in AP mode and we have to again restart the esp once router is up

[@debasishbanerjee3600]

WONDRFUL...Sachin...Tell me one thing if somehow connected wifi go down will it(nodemcu) reconnect to the wifi when it available automatically?

Yes

Why complicate when you can easily use WiFi Manager by TZapu. Its a library which handles everything and has some real good advanced usage.

[@techiesms]

Does it save in eeprom?

[@subratadey]

@@techiesms It probably does and also doesnt rely on the EEPROM Library. I use this for all my IOT projects and it never fails. github.com/tzapu/WiFiManager

*Very useful* How to change router SSID and password after connecting one router? Thank you

[@techiesms]

Just turn the router off and reset the esp, it will try to connect to the router for some time and after that it’ll create it’s own hotspot and you can add the credentials

[@elabinnovations]

@@techiesms Can we add button for that? When long press the button, the SSID and password become erase?
