Re: UART_BUFFER_FULL and UART_FIFO_OVF difference
The hardware fifo receives the bytes and then they are copied into the ring buffer in ram when the threshold is reached or at end of frame. If the hardware fifo overflows before the bytes can be copied out you get UART_FIFO_OVF. If the bytes can't be copied into the ring buffer because it is full yo...

Re: Decrease Power consumption
Power saving methods are light sleep, deep sleep, dynamic frequency scaling, ulp coprocessor, and wake stubs. Pick what works best for you.

Re: ESP32 flash encryption on flash encryption disabled bootloader
1. Encryption won't work because it has to be compiled into the bootloader but the new app should still run without encryption. 2. Bootloader does not do OTA, it is only a small piece of code that runs from ram. You still need an initial app to do the ota. 3. Not hard but practically does not add mu...

Re: FreeRTOS heap allocation at compile time.
To track memory at compile time use idf.py size. The initial heap size can increase if the compiler reserves less memory for example if it optimizes out functions and variables. Otherwise heap is dynamic and you can use heap tracing to analyse it.
