Re: how can i get the public ip adress of my esp32cam

Using STUN but you have to also setup port forwarding on your router so you may as well just use a dynamic dns service.

Re: ESP32 UART missing RX bits fairly frequently @ 115200 230400 921600

What is your level shifter and 1.8v power supply? Analog samples are taken at the esp32 pin? You could see if there are glitches when capturing samples with rmt.

Are the bad bits always low? Have you tried enabling the internal pull-up?

Re: ESP32-WROVER-B SD card access in SPI mode with the SPI pinout for the SPI Flash and PSRAM

Most code runs from flash so it is almost always busy. You would have to do a lot of tricks to get it working and it might have too many limitations to be useful.
