So what is the ota code segment we have to include in our sketch to be able to use OTA more then once?

I just found my next project… I’ve been meaning to learn how to do this. I’m going to do this over the weekend.

One "Like" is no-where near enough! Well and clearly done, thanks.

Hi.. could u please send any link or give some suggestions for installing network port. Actually I have only serial port on my arduino IDE. Perhaps some drivers might be missing in device manager

This is so cool. I tried and it worked like a charm. I like it.

If I understood correctly, this technique can be applied only once. If I want to apply additional firmware OTA updates it won't be possible because the original OTA sketch was overwritten by the Blink code...

hello, i am doing the same as you told me, but in respond its saying no respond from device, whats wrong in it. kindly help

Hello, very good video, but I am having problems with the firewall, when I disable it it works OTA.
I already opened TCP and UDP ports but it still doesn't work without the firewall disabled, any solution? thank you

Hi .. I used ElegantOTA and for most applications it works well however, if the application uses FastLED NEOmatrix the LEDs stop working as soon as WiFi is turned on.

Thanks a lot for your tutorial. At first, I got an Error Message: No monitor available for the port protocol network. Could not connect to ...network port. But when I Compiled&Uploaded the same sketch second time everything worked just fine .. Thanks again for your video, it opened up new great possibilities !

Do you have the same example with VScode?

How would it be if i want to work with a SIM module to connect the ESP32 to a cloud via 4g, to update the code of the ESP32 from any place instead of using the wifi

Unfortunately OTA takes place with the WiFi credentials shared. That means if my ESP32 was deployed in a Robot far far away, and I tried to send them this, over OTA, I would need OTA Web Updater, right? I have been trying to do that, and yet cannot seem to be connected to the local IP address, I am still just learning this, I have high hopes for the OTA features as an Intern Robotics Engineer. I am going to so use that.... Is there a video you created for the Web Updater?

Great video! how to upgrade .bin file firmware to esp32?
Espresense had ota supported already.

have a program that sends message by Bluetooth to a matrix led works well but I want to load it by OTA but I just put in the setup: SerialBT ("robotics 2") which is the name of the Bluetooth that I gave me says error when compiling for the ESP32 board, you will know why this happens, by cable I charge it well
