One idea would be to write a REST server that handles POST requests. The firmware could then be posted to that REST server which writes the image as a temporary file and then invoked esptool.py via a "System" like call and finally deletes the file. For a task like this that one wanted done quickly, ...

When an exception occurs while running ESP32 code, you can configure the ESP32 to log either a dump or directly enter gdb mode. In both cases, we see exactly the source line where the exception occurred. I think it might be useful to enable that additional level of debugging so that we can see which...

Maybe provide a description of how you built your environment? I use Ubuntu on mine. Lets look and see if there is something odd in the compiler chain you are using, the version of ESP-IDF or something else. Maybe someone can compile your program for you to build the images and you can test with a c...

For the sake of an idea to try, consider running:

make erase_flash

and then try re-flashing. This command will erase (reset) all flash memory. It is just possible that some previous application you had installed "confused" the environment.

Does the diagnostic message written to serial output contain the identity of which task is being starved?

Its a good question. I don't know WiFi and radio rules but if you are saying that the US FCC only allows radio channel 1-11 to be used for WiFi in the US but outside the US other channels can be used ... then I would also have imagined that non-valid channels would not be shown based on the country ...

I tend to suggest always go ahead and post the traces and logs but post them to pastebin.com and include a link(s). Since your forum post is public domain and you are prepared to share the traces, it doesn't seem to do any harm to post them to pastebin.

Non-deterministic or timing problems can be ugly to diagnose. If a hang is occurring, what I would suggest is to find the statement that was entered but has not returned and see if it is consistent across hangs. Without the ability to "break into" code, the best suggestion I have is to liberally spr...

When I learn something that is useful, I try and keep a snippet of it around ... my sockets snippets can be found here:

There is a FreeRTOS API called vTaskList ... see: http://www.freertos.org/a00021.html#vTaskList However, it comes with caveats (see the docs). It is also not enabled by default in ESP-IDF but can be enabled by changing the FreeRTOS config files. See also: https://github.com/espressif/esp-idf/issues/...
