ESP32 programmed OTA - no wires, no WiFi!!

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at spicing up "normal" OTA programming by using the device itself as an access point for the programming!

*This project has matured! See the new video and files:*

My scouring the internet has paid off. Thanks for the video!

nice project. just a tip.. make sure to put decoupling caps close to the chip.

If you actually look at the code in the ArduinoOTA library and see how it works, it is possible to update the board via WiFi, Bluetooth, or Serial. Some methods would be slower than others due to the amount of data you can send. You'd have to send smaller packet sizes.

You could even have a master board receive the data for the update and transfer the data to another board through the various forms of communications, that way a slave device can be updated without having to connect to an outside source.

login credential checking via client side javascript?!

so the task i have is to make an ota update once esp32-s3 receives wifi credentials via Bluetooth and i keep running into guru meditation ....your method is good but the wifi ssid and pass i cannot hardcode i will need to retrieve it via bluetooth
can u suggest something

So you mean by "no Wifi" "no internet wifi", because the esp32 in AP mode is clearly "Wifi". I have been uploading new code to my esp32 in AP mode no problem, why does this need anything other than stock esp code? I just have to connect my computer with arduino ide to the AP.
My problem is my esp8266 in station mode must connect to the AP with the specific name so I can upload new code, and I don't want to have that AP up and running just to upload new code to the station device which I then change what AP it connects to, so I need to keep the old AP up and running and the new AP up and running to upgrade all my esp8266 setup to connect to the old AP. If I could just connect to it without "wifi" like perhaps using espnow knowing just the mac address, i could not require having this old AP still up and have my pc have to connect to both

Hello. Thanks a Lot for your code. I was searching exactly this way to program my ESP32. On the other hand, i was searching in your GitHub repository trying to probe your LED configuration in mymain.h but Is not anymore. Can you upload that file please? it Is very important to clarify doubs that i still have.
Thanks a Lot again, and congratulations for tour work.

Hi
You seem to have modified the github since uploading this video.. What happened to the jquery.min.js code in your repo?
Many thanks...
