ESP32 Bootloader without BOOT pin access

[noizlezz]

Hi,

I have built a product with UART interface accessible by the user. I do want to be able to update the FW via the UART interface without using the BOOT pin.
Is there any example available how to trigger the reset and bootloader and update the FW from defined memory region without using the BOOT pin?

Thanks
Tom

I'd look at the OTA API; the lower-level API is transport-agnostic so you can also feed it data from a serial port.
