You are great man and this comment coming from neighbor I hope you understand.
Keep it up.
You are a position person.
Share video, Share knowledge
That is great! I am sho surprised that I haven't seen someone show this before. It just seems like such an essential tool.
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.
Amazing
Now just do one thing
Share video to share knowledge
Much needed thing is finally here... Thanks man!!!👍👍👍
Always like your tutorials full with easy explanation/procedures and importantly the coding as well, thanks budy.
Your method is simply Awesome!
Quite simple and useful. Thank you.
I have done it recently.
But this is simple and very useful bro
This is the most important video of this channel.
Perfect, all the best and kind regards from switzerland
Hi sir,
I am a subscriber of techiesms and learned alot of things from here.
I would like to request you to make a video on OTA(OVER THE AIR) with esp8266 and arduino uno
Super. This was my exact requirement. Thanks a ton.
Hey man thanks for the video, but i got a question, I can't connect the esp to an open network, How to save the credentials in that case?
sir you are a great youtuber
Thanks sir. For your helpful Projects And Code. Just Great job......
really good work man, kudos
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.
Thanks for sharing this video. Can we upload main software program after this wifi credential checking program? how we can upload two or three software function in one ESP for multiple functioning?
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
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.
Can we put bkynk codes inside the loop? And can we add the auth code to the external input feed? If yes then plz update on it how the whole program would be like.
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
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
Hi GREAT VIDEO!!
How can we center the web page in the middle of the monitor?
Thanks in advance!
awesome man, thank you so much for the code,
Really awesome... Can u pls say what changes have to be made in the code for ESP32?
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.
Nice content with clear explanation.
This video was very useful.Thank you for sharing this information.
Could you please let us know how to connect Alexa echo dot 3(3rd Generation) with esp8266 without using google ifttt.
Thanks
But for what about pairing device from android devices? is there any technique like sonoff is using.
Will this work when node mcu is not connected with laptop but it is connected with a 9v battery?
Thanks sir, for this video tutorial
very helpful video ......Can you also tell hot to enter the Auth token without hardcoding?
Hi I love the video but need your help to connect it to blynk with eeprom, pleaseee
WifiManager library by tzapu can also be an option. And I personally like it because it provides better interface.
Sayantan Pal I need help
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 ❤️
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
There is an if statement at line 137.... " { " and " } " are missing after this line. Will the if statement work without { ... } ?
Sir, you are great...
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
Can we also add MQTT credentials in this WiFi manager ?
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.
Great work, how to modify the ESP IP address to the EEPROM to change it without hardcode.
Still very new to this hobby so how do I add this code to a project
Bro help me how to read multiple flow sensor value and sending to firebase ..I was trying many times but I can't...help
how can I display an image (from website link) on the top of input boxes?
Can we make a flight controller using nodemcu ? ...Really appreciate your work 😍
Is it possible to run nodemcu to do following 2 task at same time in parallel?
1. It should act as hotspot for listening new ssid and password
2. It Should scan available wifi to connect with existing wifi credentials from EEPROM
Does the basic OTA do the same?
Varry useful video..... Very good keep it up
1 question can this code be used on ESP32 -CAM . And are the credentials be reset ? Pls reply to mu question and thanks
can i use this method with esp32-wroom32
esp32 devkit v1
thanks for sharing this tutorial..
Sir I have a small query that I'm unble to solve can u solve it my problem is that I want to do simple led on off using esp8266 and thinger io I have done it but after power off and then on to esp then that does not save last state it reset .means my last test is on but after esp reset that shown led is off. Or wise wersa . I want to do program as like after reset it should be shown last test ie on will be on or off will be off. Please help
Sir can u teach us about nodemcu mdns at android, so we can remember url rather than ip 192.168.4.1, thanks
Sir is there any way to set wifi credentials on air without saving it in EPROM
Can this be done on ESP-01 devices?
can we the WIFI credentials of esp modules using firebase?
Is this possible? Please tell me
will the ip address is same for other networks??
WONDRFUL...Sachin...Tell me one thing if somehow connected wifi go down will it(nodemcu) reconnect to the wifi when it available automatically?
Yes
Please suggest best wifi development board
Hello,thanks for your good toturial.
My problem is that when i want to combine wifimanager with a code that for example control a LED; I can't get the result i want to see and nothing work together.
Please help and guide me🙏❤
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
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.
Thank you bro you video are very useful for me .bro same topic how to do esp32
Just use Wi-Fi manager??
Use Wifi manager library it is the best..!! and have support for ESP32 also
Cool, very useful.
Thanks
Hello, I would like to know if I could modify the same for a code for ESP32?
Yes you can
How can make a new password for esp if i use it as router and connect to it directly
Tomorrow if I want to change the wifi given to esp32
How to do that?
Please make the video like we can control the applainces through blynk app and manual and with feedback to app at the same point we want to change the wifi credentials the whole thing in one code file ....thank you
useful video... Thank you sir
For Local network ?
Useful Bro😍
Great job...Thanks....
Can you please make a similar video to insert Telegram Bot credentials from the web browser so that device end user can insert their own credentials and get notifications on their Telegram App.
Excellent 👍

This is very very very useful. Thanks.
Share video, Share knowledge
Very useful..thankuu soo much
IS IT USEFUL FOR LONG DISTANCE?
Hi,
Can you please tell how you are opening 192.168.4.1 in web browser....?
I tried to open for the several times but encountered error again and again.
Showing the 'waiting.............' msg in the serial monitor. Every thing is OK.
But only the problem i can't open 192.168.4.1 in the browser
very disappointed.
Please tell me the solution on this.
Thank you so much ☺️☺️
How I reset old saved WiFi credentials on ESP12 by pushing reset button with pin configuration to ask New
When it reset it connect automatically with previous network but when it power off and then on it can't connect automatically with previous network
Very useful 👍
Bro how to clear the data stored in EEPROM?
ERROR SHOWING CREAT WEB SERVER ON THIS PAGE WHAT WILL I DO?
I tried it but in serial monitor reading EEPROM SSID and pass not shown just blank, waiting for Wi-Fi connection then it turned the hotspot on then the local IP :(IP unset) show soft IP : 192.168.4.1 and scan network and then it just remain waiting. esp8266 hotspot not show on smart phone or laptop and the IP address 192.168.4.1 also not open i tried many times . kindly guide me how to do it.
After installation this code can i install another codes.
I would like know which code inside esp8266-01
You need to marge this code into your own code to make it work with your project
I use this method. Rather i've modified the ui of the web page. But i don't know how to autmatically redirect to 192.168.4.1/ when i connect to esp8266 through mobile. Can someone tell me how to do this?
Nice concept
It's not working with my code. And there are many clashes btw them. First I checked it as it is, it worked. And then I replaced my main code by ur led code. But it never worked. Please help....... :(
How many passwords can its eeprom store?
keep it up
if i want to erase the wifi credentials from EEPROM then what should i do?
I lv u bro 🤘👌👍🏻
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 💭 😊
Why complicate when you can easily use WiFi Manager by TZapu. Its a library which handles everything and has some real good advanced usage.
Does it save in eeprom?
@@techiesms It probably does and also doesnt rely on the EEPROM Library. I use this for all my IOT projects and it never fails.

awesome bro ur great
how to delete or change the credentials
Did you find a way to ?
