Change & Store ESP32 WiFi credentials in EEPROM without uploading code

[@hayder.ismael]

thank you so much for this great tutorial. In other wifi managers the page to enter new wifi credential pop up automatically once it is connected to the ESP, so no need to find the IP address. just imagine in somewhere and you don't have your laptop. Is there any lins of code can enable this property? thanks.

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

Nice work.... There is only one thing that i don't understand... everithing goes ok. but if i disconnect the wan line of my router (so Wifi is present) in serial plot it write "Connection Status Negative / D15 HIGH" and it will open the AP function! If i will re connect wan cable, the ESP32 it doesn't re connect, becouse is in AP mode... how can i avoid this?

How to do same with app made using mit app inventor sir

[@hlozano32]

I spend all day yesterday doing this (I did it for myself but I would like to see you video before) thanks. My code works for esp32 and esp8266

[@electronicsinnovation]

Yeah, we can do that using "if defined"

[@ruellarobson]

I would like to know if this is possible for esp32Cam? thank you

[@dakshkalucha5408]

Please suggest if i can do the same in micropython???

[@akshaygodase8067]

I could design code to accept wifi credentials with bluetooth and then connect to wifi still this was helpful. Thanks for this video.

Esp already has that feature called bluefi. Or you can use the smart config example provided by espressif.

Is this possible with MIT app inventor? , pls make video on this topic as many of them are waiting

[@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

[@darshanpanchal3046]

yes same logic as this

[@jinshamai2918]

It works! Thanks! can you please help to make this code shorter? the problem i got is that i can only add two to 3 pins to function as input/output to control appliances. Thanks! hoping to see another video update. cheers!

Hi, I am using ESP32 WROOM32D module and trying to read and store the read values from eeprom to ssid, pass in order to then connect to WiFi automatically. Here's my snippet: ssid+=char(EEPROM.read(addr)); which is in a for loop of course, but all I get in response are the inverted question marks. Sigh, what is it that I could be doing wrong? Any help will be appreciated.

[@printshopautomation9814]

How is the access point ip address determined? Will it always be 192.168.4.1? How do users find it with out the serial monitor?

[@poruatokin]

Late response, but you can use other techniques in the sketch to force connection with a static IP instead of relying on DHCP.

[@hrbembedded_craft]

Thank you for information

[@adinajoshisatyavardhan6543]

Can u provide same for esp8266 please which helps me a lot sir

[@s.husain6125]

Great sir please make video on how to update credentials using mit app inventor created app

[@printshopautomation9814]

Yes!

[@WistrelChianti]

This wasn't what I was expecting (figured it might be some IDE function for to writing direct to the EEPROM somehow - similar to how it is possible to write to the "file system" [of sorts]) but I learnt some useful stuff anyhow. Some impressively functionality in that webserver. Feel somehow the credentials are crying out for a data structure and a layer of abstraction for read/write but of course that would not make a good basic demo for beginners. I need to go read more on the EEPROM library and see what can be done...

Thank you for the support☺️.

[@sunziv01]

To see the acces point you need to connect esp32 with laptop. Then what is the benifit of this process? Anyway you are connecting esp32 with laptop, then you can simply edit ssid and password from the code.

[@electronicsinnovation]

For the first time you are doing it From next time onwards, you can access the same with same IP which is already known to us. Or else, you can login to your home wifi admin panel and see the ip. In video, we will try to explain things as simple as possible. That doesn't mean we are so dumb to know about these issues.
