Re: Private unique id used as client secret to access https api

Don't use blk3, store it in an encrypted partition with secure boot and flash encryption enabled.

Re: Socket connect fails with ERRNO 113 with http client

I suggest you put pressure on your sales rep to get a fix backported to 2.1. I told you 100 times you would regret using older sdk versions. :ugeek:

Re: Heap Fragmentation and Deep Sleep

Coming out of deep sleep is basically like a cold boot with a few exceptions like rtc ram and wake stub. But if you want your app to resume you have to use light sleep.

Re: WROVER resetting with SDMMC_HOST_SLOT_0

It is possible to use HS1 for sd/mmc if you put the flash on other pins. The SD_ pin labels are for sdio slave mode in which case you wouldn't have a flash chip. It is definitely not ideal.

They are used for the flash chip. The app executes from the flash chip. Already told you that here viewtopic.php?f=12&t=7686&p=32347#p32394

Re: Copy efuse to hardware key registers

No, you can still use hw acceleration without flash encryption just turn it on in menuconfig and use the mbedtls functions.

Re: esp32 resets after memory allocation failed by asprintf

You are probably leaking memory. You should use MALLOC_CAP_DEFAULT.

Re: esp32 resets after memory allocation failed by asprintf

Check free memory with heap_caps_get_free_size. Don't free the memory until it is received from the queue. Keep all your related questions in one topic. Learn the basics of memory management.

Re: Wakeup-over-Wifi possible?

No, the reason it uses less power is because the radio and cpus are off.

Re: brownout detection not operating as expected

Using brownout to detect a low but stable-enough-to-do-complicated-things battery voltage is not really the intended use.
