Warning esp32-hal-uart.c function returning non-void

1

I’m new to platform-io. In my first attempt to program an ESP32 I tried a simple blinky program. I’m getting a warning, but why? Would like to build without any glitches.

Hi @chriskuku, this warning originates from the Arduino framework itself, so you can ignore it.
