The themadsens, Sorry noone replied to this when you first posted. Another longer thread discussing the same idea is here: https://esp32.com/viewtopic.php?f=13&t=5950 The short answer is that this is technically possible but there is no easy or supported way to do this. A few details: The addresses ...

For a full explanation, see here: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/system/intr_alloc.html#iram-safe-interrupt-handlers The short answer is: The restriction of only calling functions in IRAM only applies if the ESP_INTR_FLAG_IRAM is provided when the interrupt is al...

I see, thanks for explaining. I've asked the Wi-Fi team if it's possible to forward frames with bad FEC to the sniffer (promiscuous) interface.

We won't get an answer until next week, due to the Spring Festival holiday.

Hi Is there any sample code available for Multiple timer implementation using a single HW timer as base ?. Yes! This is a common enough requirement that a high resolution timer abstraction is available in ESP-IDF: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/system/esp_timer....

Sure, I can explain this: The C standard provides a standard "main routine" form, which is the "int main()" you're referring to. Microcontroller programs usually also use "int main()" to conform to the standard, even though the main() routine on a microcontroller usually never returns. (Microcontrol...

So the sync message to the ESP32 is being received via an RS485 to TTL interface chip? And the sync message is being sent from an USB FTDI chip driving a TTL to RS485 interface chip? I can't think of any reason this shouldn't work. If you have some logic analyzer captures at the RX0D pin, can you co...

Moderator's note: Moved to Arduino subforum as this question is about an Arduino library.

If you use F3 to "go to" the source file represented by the "#include esp_log.h" line, does it go to the correct source file? Are that header file's recursive includes properly referenced?

1. For read, how does one decide how much to read? For example, if the 2MB region that was read consist of multiple files, how do I extract them from flash_contents.bin? The flash region may also have been read partially, that is one of the files is stored beyond the 2MB mark, how does one avoid su...

Do I understand correctly that you want to be able to receive invalid 802.11 data frames? I don't think this is possible on ESP32, the lower MAC layer discards them at an early stage (it more or less has to, in order to maintain good throughput of valid frames.) Maybe I don't understand your full pu...
