I'm Portuguese, so I can read Castellano with some easiness.
Very interesting article... Somewhat complex, but doesn't imply a modified bootloader.
I'm not sure if it couldn't be applied to a weather station... if the upload process fails, it implies accessing the system locally, and it also imply closing the connection (during programing and rebooting) with the weather software running on the PC, which may also cause some problems. But could be very interesting for the TX units, per example...
Thanks for that info.

It's just an example created less then a month after the SDK was available late october 2014.  Later there was made a library to do that. I'm using OTA in my Wifi enabled beerfridge and until now i never saw it fail. When i have some time i can take a look at this, i have some spare Esp's and a Meduino alike controller laying arround here. Also an esp32 is on it's way.
