Re: WiFi STA fail to connect in enterprise AP.
Any ideia? This make no sense to me. I've seen other reports of this type and I think the problem is in enterprise WiFi, but how to solve it? What can I do?

WiFi STA fail to connect in enterprise AP.
Hello guys, I need some help with "enterprise" WiFis. With my home wifi or mobile AP (hosted from galaxy s8), esp32 always can connect correctly and get dhcp ip. However, here in my job (enterprise wifi), esp32 fail to connect OR fail to get DHCP or connect sucessfully. (random) Please, help me to f...

Bootloader timestamp
Timestamp used by bootloader and 2nd bootloader is CPU cycle counter and after scheduler are RTOS tick, OK. However, I tried to find time that RTC WDT is enabled and found one curious detail: Timestamp go back (rollback) before RTC WDT, why? Line with "chip revision" = 89 cycles Line with "bootloade...

Re: How many write/erase cycle on flash??
How many writes one simple nvs partition (4KB) with default wear leveling (4K) can do approximately? I need numbers and how to math this?!
[4K*4K*100K(flash write cycle)]/data_write_size(1B) = 1.6M writes ??

Re: Can the WDT be routed to a GPIO pin
As most of us know when you starve the CPU core your going to get a WDT warning in the terminal. I am curious if there is some kind of ISR hook or other call that can be implemented in code so that if it gets triggered I can toggle a GPIO pin. Task wdt has weak handler and yes, you can do this. esp...

Re: eFuse factory already wrote
Obviously, that shouldn't happen. Is this consistent across readouts? This only happens with one module/chip, right? What is the MAC number? Yes, all eFuse read are the same value. Yes, I noticed this behaviour only one time in my life with esp32. Summary above has MAC (MAC Factory MAC Address = 3c...

Hello! I want to know about de chances of eFuses become burned from de factory :lol: In this week, I'm uploading all boards from my job and in process to burn flash key, tool tell's about already value in keys.

Re: C library linkage fail in C++
It looks like maybe your main component.mk doesn't add the "tinyexpr" subdirectory to COMPONENT_SRCDIRS? This means the tinyexpr.c file is never compiled as part of the build. The hack where you #include "tinyexpr/tinyexpr.c" main.c works, because now the files are compiled as part of main.c. Check...

Re: Approximate reasonably CPU load per core?
Folks, Is there an "official" way to read the approximate CPU load e.g. how much time is spent in IDLE vs other tasks? I'd ideally need this per core, tips on how to achieve that would be appreciated. Thanks With RTOS stats, you can see task usage of all tasks of both cpus (including IDLEs) https:/...
