After hours of reading I understand I need to set pin to low/high when receiving or transmiting. So I need to set pins (basically one pin for both on RS485 component DE & !RE) to high/low. Those pin is in my case connected to RTSA pin of UART which should do this job automatically based on datasheet...

Did you look at the examples included in esp-idf already?

What about components which I use, should I also define them somehow? Uart expander (SC16IS752IPW) and RS485 (SN65HVD72D)?

Hi, I have a question, so I have two identical devices that I would like to communicate via RX / TX (RS485). Both devices are exactly the same component, but as far as I know this is half-duplex mode, which means the first device sends, the second device receives and then again the second device rec...
