I want to use serial to show income data but no luck. Serial is empty. Do I need to add code to print in computer serial?

Hello I'm trying to read registers of a rs485 device but this code isn't working, how you re assigning rx 15 and tx 13 for serial2 in esp32?
serial2 has the tx pin 17 and rx 16, so I'm confused is there any solution to read the rs485 registers using the KC868-A8M board?

our demo code can't work well?

Thx for Your fast reply,
No I tried to connect the KC868-A8M to a sensor, to read data via RS485 and  I didn't get any result using the demo code

you need modify code according to your sensor's protocol.
