How to use uart rx interrupt in esp32 arduino?

Postby ahendml » Sat Jun 21, 2025 7:55 am

I am developing esp32 in Arduino environment.
But is there no way to implement rx interrupt in Arduino environment?
It seems possible in esp-idf, but how can I implement rx interrupt in Arduino environment?
Thank you.
