Hello,

I have connected my Raspberry Pi 4 with a Nextion display, which is modified to have a text box and a button.

I have successfully sent a message for the textbox to display(UNICODE is the only problem with that, since Nextion displays can only display English characters), but for the love of God, I cannot get a serial input from the Nextion screen(when the button is pressed), although it states that it is connected normally.

Has anyone else had this problem? I event tried it with an RPi 3, same thing. I can send but I cannot receive anything.

Thank you for your time.  
John

Choose an option "after silence of", all must work fine.

My settings for Nextion
