Can you wrap your code in 3 backticks (each on a separate line) so it is better readable? And if you really want to do it fancy, add `c++` right...
Ohh great! Looking forward testing it.
I have not tried using Virtualbox, but I do now use WSL along with VS-code on Windows as it is a lot faster (3x - 5x faster) to build my...
What board do you use? GPIO-16 and 17 are also used for PSRAM, so you have to make sure PSRAM support is disabled or else polling may perhaps offset your...
Just some other idea, inspired by this PR for Olimex boards: https://github.com/espressif/arduino-esp32/pull/9623 Maybe you can also experiment with setting the GPIO drive capability (drive strength) when using ESP generated clock.
Ah that's a different problem. You 'simply' need to decouple the clock from GPIO-0 before boot. On some crystals there is an enable pin. Maybe you can route some GPIO...
This is how I did it on a board I made which is using those Ali Express LAN8720A chips (with 2x7 pin header)  The chip I used is TS5A3157DCKR...
Have you also tried to set the channel again after scanning is done? I have noticed the actual channel set to WiFi may remain at the last channel used, when...
> I'm also sure that you _have_ to switch to STA mode for ESP-NOW to work. Nope. As a matter of fact, ESP-NOW does work perfectly fine using the AP...
AP mode doesn't do anything other than guaranteed not going to "radio sleep". So it is much more "available" to send data to.
