Enter Blynk Credentials Over the Air in ESP32 or NodeMCU board | ESP32 projects | ESP8266 projects
HTML-код
- Опубликовано: 14 окт 2024
- In this video I have shown how you can enter the wifi ssid name, password and blynk authentication token wirelessly to your ESP32 or NodeMCU board though your web browser. So now no need to hard code all the things inside the code.
You can change the credentials anytime you want without updating the code. Have a look......

Excellent !!, Actually you're my role model. I am from IT industries and Robotics is my hobby, I learned so many things from your channel. I got interested in robotics because of you only.
आपके इस कोशिश से कई लोगों का फायदा हो रहा हैI
If possible please make energy meter on blank platform
Thanks !!
Brother you did wonderful work in this tutorial.
Thanks for the amazing information and code which u was shared with us
...
you are one of the best best youtuber in this world
Very good tutorial, friend, I only have one query ... how can I change the SSID, PASS or AUTH TOKEN over and over again, in case you go to another place that has another WiFi, please ... kind regards
I had to add a line in your code, because the AP was not turning off when the NodeMCU was connected back to the WiFi. I added WiFi.softAPdisconnect(true); in the credentials_get() fuction, and now it's fixed.
very good idea, I want to ask what if we use a server other than blynk for example using a local server using an ip address? which part should I add the program to my local server?
Thanks sir
i have a problem in this code during compiling it shows "error compiling for board nodemcu 1.0 (ESP-12E MODULE) please give me a solution
Hi Sachin great job👍.
The reason why your esp8266 doesn't get auto reset is you need to use ESP.reset and not ESP.restart
(ESPAsyncWebserver.h : No such file or directory )
Dear friends this problem occur
Kindly plz help me
Thanks a lot
How can i add this Library i can't found it on library manager and chrome
Sir can you make video on Blynk 2.0 on same topic
They already have this feature BUILTIN
great job! but I wanted to know can I use this code for the home automation project as shown in one of the videos where u use siniric to control over the product for manul with feedback, can u let me know if it's possible that we can remove the blynk libraries and use siniric to type myApi key by air to esp32.
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
Such an amazing achievement that you share with us. I am glad to thank you to give helpful and creative ideas. I am waiting for the same thing possible with the internet and manual control of home appliances.
In the esp8266 node MCU in which pin the button and GND should be connected ?, please and in the case of the esp8266 01S, also where does the button go? ... thanks.
Thanks very much for the very useful code. FYI I had to install the AsyncTCP library from Github to get it to work. Regards
Great break down of the code . Only one question is there a way to autoreset?
Brother, you really won my heart I was finding this solution for very long, and here you go.
I will really support you.
I just need one more help from you, can you make a Blynk code to work without the internet, actually, I was trying to build my project with ttp223 touch switches with Blynk app, both are working side by side means when I turn on the touch switch the button in Blynk app get turn simultaneously on and vice-versa.
But this only happens when the Blynk app is connected to the internet, without internet even the physical touch switches are not working.
Can you help me with this - how can I create that project in which the touch switches works with or without the internet along with Blynk app.
And once again really thanks, brother, one more thing I want your new series on Javascript and Websockets.
Good explanation and you are funny. Can it work with other iOT servers?
Hi,
First of all, appreciate your hard work and elegant explanation.
I modified your code to work with Firebase Arduino, at first it didn't work because your code uses ArduinoJson v6.x.x whereas, FirebaseArduino.h is not compatible with this version, rather v5. I had to change your json parsing method from v6 to v5 style. I also added another text input field in HTML to get firebase host address along with authentication token. I tested it on my firebase project, works like a charm.
However, I found that the reset button method doesn't work, once the credentials are stored, reset will erase the EEPROM data successfully, but would not start AP again. Code always gets true return from _testWifi(). I checked it by forcing false return in this function, it starts AP then.
Can you check again if it is working smoothly in your code? or can you help resolve the problem?
PS: you can make a video with firebase credentials instead of Blynk, this is missing on youtube, would be useful for audience.
Where van I download the first library ESPAsyncWebServer? I have an error, it's missing library. Pls help me!!! Great video!!!!
Hello, I have the same problem, if you managed to solve it I would appreciate your help.
same issue if find solution please help
same problem but i solved it just by installing another library to arduino IDE github.com/me-no-dev/ESPAsyncWebServer.git
@@ehtishamliaqat9510 try installing library from github.com/me-no-dev/ESPAsyncWebServer.git it worked for me
@@abdulrehmankhan5427 I have a problem.At last when i connect to the wifi by 192.168.4.1 blynk app can't connect to the wifi.So I can't control anything. How to solve this problem.
when I connect it to the wifi blynk app means the phone which has installed blynk app is everytime connect to the same wifi ?
And I connect to the 192.168.4.1 server to the other phone ?
Please help me 😓
First of all, Merry Christmas. Excellent contribution to the esp8266 module. I have a problem when loading the code, I can delete the eeprom, could you explain how it is done? Thank you very much.
Also I am junior full stack developer so I understood you very well and I would love to see more explanation about code :) It's easy to when you explain :+1
thank you sir, very helpful code.. it means no hard coding again just reset then put again the credentials is that right sir techiesms?
There is already a library called Wifimanager. And also a OndemandPortal example. After watching the entire video i felt that was more handy with automatic portal login especially on iPhone's. I did not find anything new in this. Correct me if i am wrong. I am not trying to say that the tutorial is useless or anything negative, just my opinion on it.
Can you please make a tutorial where in we can control multiple esp8266 boards with ESPURNA firmware? Because to control individual boards we need to login to its AP every time and its annoying. If you make a tutorial on this it would be helpful, and also explain how to schedule devices.
Thank you.
this procedure works for ESP8266 01S ?? and as it is possible to do it, to see if you can send me some information, please. Thank you.
how can i add code to make it reboot after say 5 mins if in access point mode? for example we have many power cuts my arduino board will boot up faster than my router and i don't want to have to go around and manually reset my board all the time? as it will be outside as using it as a water tank sensor. also can i make it so it only changes the wifi not the char auth? thanks in advance.
No job bro I can't afford to subscribe your plans .but this is the channel which I daily use to check for new video
Wow, it is what I want to do and just wonder how long I need to work on this. Now, it is 1 min work. Thanks so much.
Glad it helped!
Bro you did wonderful work in this tutorial.
Thanks for the amazing information and code which u was shared with us.
Can you please make tutorial using android app using mit app inventor.
Awesome work bhai, it is really a very cool and useful feature. I am hoping to see more videos on NodeMcu. More power to your work. 🔥❤️🤓
Well real hardwork goes behind this kind of effort...
👍👍👍
Super Thumbs up....
Your Passion can be seen...
I love your projects, incredible , wonderful. Totally worthy for IoT projects. Thanks
May be exploring javascript library more has a way out...
Javascript library modification can just be awesome brother..
Sir please you continue to making the searise 😄❣️
Hello Bro, it is a great work and brilliant idea. I wish you can teach us on how to fill in Static IP, Gateway, Subnet, DNS1 and DNS2. Thanks a lot for your kind sharing and very much appreciated. if I can fill in Static IP Gateway, Subnet, DNS1 and DNS2, cant wait you teach us all.
Hi, thanks for sharing the splendid video. I was able to do it successfully on a nodeMCU, but the Wi-Fi settings doesn't save after a power offing for some time. Do you think I have done anything wrong? please respond if you have free time. thank you.
Actually now you don’t need to follow this technique
As the new Blynk app has this feature BUILTIN
@@techiesms so how should I do it?
Yes sir.. jarror...bnaiyega...is pr..
Video mst h..aj ki.. coding ♥️...
Thank u sir mne bhi ye bola tha..video bnane ko.♥️🚀
Awesome!! Superb!! I m also searching to connect Blynk with Google assistant..Please help
Did u configure google asst...
Great video, this will allow me to share some of my projects because all their credentials are hard coded at the moment
Thank you sir , for this wonderful vedio . sir i have one moew doubt suppose one more time i want to change ssid and passsword how to do that
Please tweak this library so it can be use with ttgo esp32 sim800l. Make a provisions where you can put the ISP name and password and also blink authotoken. Thank you for such a great effort
Great tutorial, and sir.. can you make a video about esp32 login to web wifi? Like after you connect the wifi it request a login on a web.
Any idea how to add switch button to the same setup page of wifi manager?
Yes bro.... Make that series.... Will help us all diy guyz a Lott....!
Great tutorial. Can you make a tutorial to automate curtains/window blinds using blynk and esp
Bro 😎 great project. Can make video on how did you make labrary file .
Thank you very much Sachin Soni for the beautiful work.
A Question: I switched the name esp_ssid and esp_pass but they didn't write to ESP. I tried to erase all the memory, but now only the information ESP_ and the MAC number of the device appears.
Can someone help me?
Is there any way to do so for Arduino IoT Cloud ? it will be super helpful.
Is there any plug in available for Arduino to upload eeprom data Like "ESP32 sketch data upload" or "ESP8266 sketch data upload "
This channel always be rocked.....by creating a innovative projects....
And my request to make a project by combine this "credentials code" with iot "with and without internet manual switch code" and do a new video for this......
""I am eagerly waiting for this new video""
please look into WiFi manager with blynk for esp8266 and esp32 and make a video about it. the wifi manager interface looks better
Yes sir, creat Java and Web Socket series.
easy to grab ...please do the project with FPGA and esp32 controlling some sensor like temp humidity...
Very great explaination, and waiting for the websockets, js series
Yes sir, please make a video separate series on WebSocket server and JavaScript.
Can you dynamically change the WiFi ssid ? BY CONDITIONS
Good day sir, I am having a problem, I was able to update my EEPROM with the correct ssid and authentication, and my nodemcu is connected to the wifi but the blynk app still showing my device is offline.
Yes Sir i want to learn about Java Script,Websocket and what ever you used in this project.
So Can you please make that episode.
Hallo Techiesms,
First of all : Verry good Job!!! Thanks for your work.
Does this works also , if i am using my own Local Bynk-Server.? And not the Server inside the Cloud. And if it is so. What I have to change in your Code to get it up and running.
Thanks in Advance for your help.
Regards Juergen
I have the same problem
Thank you. But now This old blynk is closed na ?
Only Blynk IOT V2.0 only Available.
Man I linked nodemcu with my air cooler but with only my router credentials. But it will help me alot to change that credentials OTA
Hi, when I press for more than 4 seconds the reset button on my NodEMCU ESP-32S don't erase the SSID, password and token information. From the serial monitor, the board try to re-connect to the previous input data loaded.
is it possible to implement the reset using code? how can I do that?
Nice & Hard work.No any other video like this on youtube on this topic
Hello... can i know how to add oled display for this code
omg!! why this video is not bilion :( I don't know to how to thank you bro. You well done work and explained well :D Thank you very much
Just a Suggestion....
Why r we Restricted to Blynk...
Firebase can also provide the only thing Blynk provides...
AUTH TOKEN !
Why not get real-time data from firebase database instead of Blynk servers.
This gives a wide scope for Android studio made apps to be connected to esp8266...
Does this work with devices which aren't driven by Blynk but another application?
Hi... very nice project and very useful..looking more projects from you
sir, please tell us how you converted the image to an array for your m5stick c
Bhai aap ke pass yh OTABlynkCredential library ka link hoga
my nodmcu esp12-E Dosen't support this code.what i need to change for using this code?
great .. that's what I've been looking for for a long time.. it has worked for me you are a great person thanks, the only thing different is that it doesn't show me the name that I choosed in esp_ssid but it shows me esp-async
I am in the same situation. Were you able to change the esp_ssid and esp_pass?
If so, could you tell me? Thank you so much.
@@drcanalli no, I couldn't change it
Dear Sachin.
I included the zip folder named OTABlynkCredentials.h which i downloaded from github.
but ,when i try to verify the code it shows specified folder/zipfile does not contain a valid library???
Download the zip file provided by the techiesms in the link given in the video description.You don't need to download any seperate 'h' file, all the three files( .h, .ino and .cpp) are included in the zip file.Try to keep.ino, .cpp and .h files in the same folder, and then open the.ino file and after the program is opened up in arduino ide make sure all the three files are opened together.
Yes. We need that series
Thanks sir your explanation and demo is superb
Very nice an useful! However, I am unable to use any other pin for the erase button . Only pin 0 works. If I set the erase button to pin 4 for example, the program is erasing the SSID, PW, and auth token immediately after writing them to eeprom. Can I use any other pins for the erase button?

Hi sir could you give us the IP address of the phone
but to run this we need dual channel network acceleration, as the blynk needs mobile data and the node mcu needs wifi.
is there any other solution for this?
thats mux in relay? so it cannot run more than one relay or its a io expander?
honestly this is one of the best tutorial videos i have seen.... Got a lot of insights.......... please i will love to connect with you, how can i be able to connect with you
Bro which button push to erase credentials of wifi ssd and auth token
Yes, Sachin Sir, Create Java and Web socket series... :)
Nice sir i try and use 1 button in blynk to reset credential password working verywell
But i want that button press for more then 4 second then password reset and also their is link so that on click we can open web 192.168.4.1 on single plateform like in blynk it this possible
Easy explanation. Very useful.
Sir can we display ECG graph in blynk app, if possible please try to make a video on that
you are great. explained every thing very well.but ,how can i add this library to my Arduino IDE????OTABlynkCredentials.h

You are awesome brother. It is really a great video to learn from
You're a genius! ❤️
Yes sir, is working but, if i delete eeprom from button, i cannot connect second time to remake the connection. And i have a question: I want to use with a local server, where can i change server and port?
Thank`s!
Same thing happened for me. The solution is to call the the function which makes Nodemcu as AccessPoint, just below the line of code which calls the eepromclear.
Then re-upload the code and it should work fine. Make sure you press the reset button if you want to clear the eeprom to add new credentials and immediately press and hold the eeprom erase button for more than 4 seconds.
