Grab the code for this over on www.kevsrobots.com/blog/micropython-ota.html

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.

Very useful, thank you!

@tech.valiant 10 месяцев назад

Definitely useful, thanks Kevin!

Going to give this a go!

your videos are so well done , thanks a lot

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

@Mr.FarePlay 10 месяцев назад

Perfect ❤ thank you so much. I may need to adjust it to read the file list from the version.json file to fit my need 👍

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?

@pierre-yves_baloche 10 месяцев назад

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 😅

@kevinmcaleer28 10 месяцев назад

Oooh I'll check the PR! Thanks for contributing to this, I seriously appreciate it!

@HopWorksET 6 месяцев назад

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!

@cparker4486 10 месяцев назад

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

@kevinmcaleer28 10 месяцев назад

You could set a variable to the current time at boot, then grab the time in a loop to compare it with the boot time and if an amount of time has elapsed (say 24 hours), then check. Have this in your main event loop

@@kevinmcaleer28 If your app already are connected to WiFi, can this interfere in any way?

@papalevies 10 месяцев назад

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

@kevinmcaleer28 10 месяцев назад

No, the script runs at startup (the main.py) so the code demo’s will connect to Wifi and pull the latest version if required.

@stevegale4215 10 месяцев назад

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?

@kevinmcaleer28 10 месяцев назад

The risk maybe low but the impact would be very high, so I’ll stick to keeping it secret!

@stevegale4215 10 месяцев назад

@@kevinmcaleer28 yes I just wanted to make sure I was not missing something, like it could be hacked remotely
