I have A16 device, in this device all peripheral work perfectly, but in RS485 case only sending operation work.
I tried various things for this using ESP-IDF, but the signal is not received.
Can you give me a simple example of sending and receiving signals via RS485 in KC868-A16?

which code you are using? if you have source code, you can test download it by arduino IDE. if you just download BIN file by "esp download tool" , mostly is set the address incorrect.
