Hi @sara,

I am trying to connect a y4000 to my arduino using an mkr 485 sheild (RS485) for hardware serial port using your arduino library for y4000, till now with no luck.

I suspect it is because of the “AltSoftSerial” creating software port while I am using a hardware one, but I am not sure how to modify this.

Can you please help with some tips or thoughts?
