Hi,
did you manage to resolve that problem and use ESP32 in slave mode?

thanks!

I would like to know which of the two cores of the esp32 is used to run the background tasks like WIFI and Bluetooth. Would it be possible, let's say core0 runs the background tasks, that I can use core1 and have it free of any interrupts? I wrote a small test program which uses core1, just toggling...
