Re: Delay booting
Is it possible to add a delay to bootloader ? - feature ewquest :-) You can't do anything before the 2nd stage bootloader starts - untit then the code is executed from ROM. If the brownout feature would work this could be also a possibility - but I use WiFi and then it is not working. Brownout work...

Re: 32.768kHz RTC Crystal recommendation
I'm using this one with 12pF capacitors on my custom boards with ESP32-WROVER and never had any issue.

Re: Is it possible to force using the internal oscillator instead of the external 32kHz crystal
If you set → Component config → ESP32-specific → RTC clock source (Internal 150kHz RC oscillator) in menuconfig, external crystal won't be used.

Re: Best way to get 16MB WROOM modules?
alb32-wrover doesn't have any certificate, plus GPIOs 16&17 are not connected (used for SPI-RAM) and that could be a problem if the board is designed for ESP32-WROOM and uses those pins.

Re: New to ESP32. Which one should I buy for my specified needs?
@RetroZvoc Maybe some of those RISC-V boards could be better choice for your needs. K210, dual-core RISC-V 64bit chip, used on them is only couple of months old and you may have some difficulties in setting the development environment, but it is very promissing. I've ordered couple of boards, and I'...

Re: Crash
Too bad there is no instruction to update the IDF. What kind of instructions would you like? The only thing you have to do is to execute: git pull git submodule update --init in esp-idf directory. If anythig goes wrong, just delete the whole esp-idf directory and do the fresh clone: git clone --rec...

Re: ESP32 PCB Antenna Design
There is nothing special about PCB antenna design for ESP32. You can use any WiFi antenna design, including ones in the documents you mentioned.
