Do you also record esp_deep_sleep_get_wakeup_cause to make sure it is a timer wakeup each time?

Fully-fledged or fleshed out maybe. Or is it an Aussie thing?

What about ROM loader considerations?

So, the failure I've got could happen to anyone who leave the pin floating, right ?

No I don't think so, this is talking about D2WD. WROOM32 uses D0WD.

Data sheet says 30% and 70% of supply voltage

Hopefully espressif will consider making a 128 or 256mbit version a standard offering especially with this new feature https://github.com/espressif/esp-idf/co ... 7468897325

I think many customers would be interested.

It shouldn't have to be LWIP_SOCK_OPEN status to be allocated, just have no netconn.

You can possibly remap flash pins in efuse to boot from another chip. Maybe changing 1-2 pins is enough? Or you could have OTA stored in external flash and custom bootloader, although you said you don't have the pins. I think it is somewhat likely they will start making wroom32 with bigger flash as ...
