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

@Tony770jr 2 года назад

The ESP32 can only connect on 2G, 2.4Ghz, not on 5Ghz.

@desgeneradotv

ok video is almost accurate while still missleading. at least in my case when trying this method by the time you upload the 2nd code with your actual code it will stop to work OTA. you need to actually mix your code with the OTA code for it to work consistently otherwise it will only work the first time. thought maybe somebody else could save some time, peace!

@user-cw3vo8hv5u

Simple, but I tried it to no avail and the internet is full of viral videos.

@BeyondGTZ

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...

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.

What kind of sorcery is this?

@tonyhodgson6744

Hi, Ive uploaded the Basic OTA into my ESP32 ok, got the IP address OK, but when i try to upload the blinky code it firstly asks for a password... which i just type my windows password as i dont understand this, anyway it proceeds to upload via the 192.168 network but only gets to 2% then flags an error, does anyone know why... thanks

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?

Hi, Great video and so much better than a bunch I have seen on here. How do I implement/combine the code so that I can run this more than once? You bring this in to make it OTA, but then you only get one shot at the OTA, then you have to go and plug it back in again. HOW is it possible to have the ability to do this forever?

@ZookeeperJohnG 2 года назад

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

@vladimirastrelin1719

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 !

@atlantikus77 Год назад

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

@talhasami150 Год назад

Hi, great work . Is there any tutorial on how to implement/combine the code so that I can run this more than once?

@Gorkilein

Great but once Blink is on there and the OTA Sketch therefore overwritren with blink I can't update my Blink sketch anymore OTA because the Sketch was changed right?

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
