Your tutorial was super helpful! Thanks.

[samidudigital]

your videos are so well done, thanks a lot

[datguy]

Thanks I was trying to figure out how to do OTA for an ESP32 kit device... Hopefully I can use this technique!

[rickrandazzo]

ok - new subscriber. I plan to do something like this. I wish you would give a code walk-through. But your code is easy to follow. Thanks.

Hi Kevin,
Great project as always!
I've created a PR to it as you could be using the commit id as the version instead of having to declare it in another file.
Looking forward to hearing your thoughts on it 😅

Would writing the OTA functionality directly in C using the Pico SDK be possible and more efficient? Would C make a noticeable difference in compute/power efficiency?

Thank you for your very useful video! Kevin. May I know is there a way to check "version.json" when my repository is set to private? As the URL of raw githubusercontent varies every time .

[HopWorksET]

Thank you! This will make updating my deployed projects so much easier to update!! I do have a question though... is there any support for private repositories, where it could use my github token? I noticed another OTA on github that does this, but not nearly as well explained as yours. Thanks for the contribution!

Q1 - is this inernet fota or intranet fota meaning to get ota update should both the device and the iot be in the same network or does it work even on different network meaning say ur iot device is in somewhere else connected dto different network and ur doing ota from ur home using ur wifi

q2- can this be implemented like this the fota code is in python but my iot code is in c so it will replace the c files moment fota is done

[cparker]

What would be the ideal way to schedule this so an always-on device checked on a schedule?

[OttoDIY]

This works great for .py files. Would it be posible just with usb cable without wifi? How to do a micropython auto updater that you do not need to worry about which version is out?

Hi Kevin, i have a code that writes datas in text file how will i make it update the github repository with the text file

[GenesisTech]

Thanks so much for this video. I’m converting my embedded device from ESP32 to Raspberry Pi due to better device capabilities. This OTA is much simpler.

One question: I have multiple files that I want to download, for example some small video files as well as the main .py code. How would you suggest doing this? Thank you!

[BenjaminEHowe]

I've noticed that a lot of MicroPython devices struggle with verifying TLS certificates. Have you added anything to help with this / prevent "man in the middle" attacks?

[papalevies]

How is this OTA? Isn't the device still connected via USB when you run the update script?

[stevegale]

I will give this a go.
I notice you hide your SSID and password, I am not suggesting you make it public but for this to be of any use to anyone, surely they would have to find your address and camp outside your house?
