OTA via smartphone via bluetooth

[mikl604]

Good day to all!
I'm trying to figure out how to update the firmware over the air, but something is getting tight.
I have an ESP32-WROOM-32-N8 device. I want to implement OTA via classic bluetooth. That is, so that the device connects via BT to a smartphone with Internet access and is updated from there.
I looked at the examples, but it's kind of complicated.
Maybe there is a simpler example on esp-idf?

I'm afraid that you'll not find any direct example if esp-idf. You will need to do it all by yourself.
