Good morning.

I am developing an ESP32 code where I use UART communications.

I want to know how can I wait until I have a delimiter on RX data or I wait X time, at the same time,

int uart_read_bytes(uart_port_t uart_num, char* buf, uint32_t length, TickType_t ticks_to_wait) always wait the number of ticks specified and I want to don´t wait more if I have the response.

Does anybody know how to do that?

There is an example in the examples folder for doing just that.
